I want to send an sms to all saved contact only by shaking the phone. But i don't know how to link the database of saved contact and the code of sendind sms. Please help me with that.
This is the code for sending an sms by shaking the phone :
public class SensorService extends Service {
private SensorManager mSensorManager;
private Sensor mAccelerometer;
private ShakeDetector mShakeDetector;
public SensorService() {
}
#Override
public IBinder onBind(Intent intent) {
// TODO: Return the communication channel to the service.
throw new UnsupportedOperationException("Not yet implemented");
}
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
return START_STICKY;
}
#Override
public void onCreate() {
super.onCreate();
// start the foreground service
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O)
startMyOwnForeground();
else
startForeground(1, new Notification());
// ShakeDetector initialization
mSensorManager = (SensorManager) getSystemService(Context.SENSOR_SERVICE);
mAccelerometer = mSensorManager.getDefaultSensor(Sensor.TYPE_ACCELEROMETER);
mShakeDetector = new ShakeDetector();
mShakeDetector.setOnShakeListener(new ShakeDetector.OnShakeListener() {
#SuppressLint("MissingPermission")
#Override
public void onShake(int count) {
// check if the user has shacked
// the phone for 3 time in a row
if (count == 3) {
// vibrate the phone
vibrate();
// create FusedLocationProviderClient to get the user location
FusedLocationProviderClient fusedLocationClient = LocationServices.getFusedLocationProviderClient(getApplicationContext());
// register the listener
mSensorManager.registerListener(mShakeDetector, mAccelerometer, SensorManager.SENSOR_DELAY_UI);
}
// method to vibrate the phone
public void vibrate() {
final Vibrator vibrator = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
VibrationEffect vibEff;
// Android Q and above have some predefined vibrating patterns
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.Q) {
vibEff = VibrationEffect.createPredefined(VibrationEffect.EFFECT_DOUBLE_CLICK);
vibrator.cancel();
vibrator.vibrate(vibEff);
} else {
vibrator.vibrate(500);
}
}
// For Build versions higher than Android Oreo, we launch
// a foreground service in a different way. This is due to the newly
// implemented strict notification rules, which require us to identify
// our own notification channel in order to view them correctly.
#RequiresApi(Build.VERSION_CODES.O)
private void startMyOwnForeground() {
String NOTIFICATION_CHANNEL_ID = "example.permanence";
String channelName = "Background Service";
NotificationChannel chan = new NotificationChannel(NOTIFICATION_CHANNEL_ID, channelName, NotificationManager.IMPORTANCE_MIN);
NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
assert manager != null;
manager.createNotificationChannel(chan);
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, NOTIFICATION_CHANNEL_ID);
Notification notification = notificationBuilder.setOngoing(true)
.setContentTitle("You are protected.")
.setContentText("We are there for you")
// this is important, otherwise the notification will show the way
// you want i.e. it will show some default notification
.setSmallIcon(R.drawable.ic_launcher_foreground)
.setPriority(NotificationManager.IMPORTANCE_MIN)
.setCategory(Notification.CATEGORY_SERVICE)
.build();
startForeground(2, notification);
}
#Override
public void onDestroy() {
// create an Intent to call the Broadcast receiver
Intent broadcastIntent = new Intent();
broadcastIntent.setAction("restartservice");
broadcastIntent.setClass(this, ReactivateService.class);
this.sendBroadcast(broadcastIntent);
super.onDestroy();
}
}
And this is the code for saving contact number :
public void storeInDB(View v) {
Toast.makeText(getApplicationContext(), "Sauvegarde commencée",Toast.LENGTH_LONG).show();
name = (EditText) this.findViewById(R.id.textView1);
number = (EditText) this.findViewById(R.id.textView2);
String str_name=name.getText().toString();
String str_number=number.getText().toString();
SQLiteDatabase db;
db=openOrCreateDatabase("NumDB", Context.MODE_PRIVATE, null);
db.execSQL("CREATE TABLE IF NOT EXISTS details(name VARCHAR,number VARCHAR);");
Cursor c=db.rawQuery("SELECT * FROM details", null);
if(c.getCount()<3)
{
db.execSQL("INSERT INTO details VALUES('"+str_name+"','"+str_number+"');");
Toast.makeText(getApplicationContext(), "Enregistré avec succès",Toast.LENGTH_SHORT).show();
}
else
{
Toast.makeText(getApplicationContext(),"Nombre maximum limité atteint",Toast.LENGTH_SHORT).show();
}
db.close();
}
Honestly i dont' know if you can send SMS to a list of contacts.
If you read this documentation:
https://www.tutorialspoint.com/android/android_sending_sms.htm
you'll read that the APIs receive MAX a telephone number.
I think this implementation is also due to a protection that android creates for avoiding to send a lot of sms togheter.
Assuming you have saved 1500 contacts on your device, your APP have to send 1500 sms???
It's strange....
But of couse you can create a loop and send a SMS a time...
I suggest you to:
detected shake gesture
retrieve all contacts saved (https://www.jackrutorial.com/2018/06/how-to-get-contacts-in-android-display-into-listview.html)
send a sms a time.
The problem occurs on Android older than Oreo and both Oreo and newer.
I can't get geofences working even though following steps are done:
Location services are set to High Accuracy
Wi-Fi and mobile data are enabled
Application is granted location permissions
Google Services are added to the project
Google Services and Play Store are up to date and installed on the device
Disabled battery optimizations (testing purpose)
I've checked with the following code if GPS_PROVIDER and NETWORK_PROVIDER are enabled:
#Override
protected void onResume() {
super.onResume();
LocationManager manager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);
if (!manager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
Log.e("Provider", "Provider is not avaible");
} else if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER)){
Log.v("Provider", "GPS Provider is avaible");
}
if (!manager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
Log.e("Network Provider", "Provider is not avaible");
} else if (manager.isProviderEnabled(LocationManager.NETWORK_PROVIDER)){
Log.v("Network Provider", "provider is avaible");
}
}
Those both above gave me positive result, so problem can't be here.
Exact error:

This code is almost the same as from Google Documentation.

Gradle:

Can anyone see the mystake I could have done?
Thanks in advance!
OK this is a minimal working program for geofences based on you OP - just to rule out your code implementation - there's a couple other interfaces implemented for other tests so ignore.
"Working" means it successfuly adds the geofence.:

GoogleApiClient.OnConnectionFailedListener, LocationListener, ActivityCompat.OnRequestPermissionsResultCallback {

Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_EXIT).build());
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION)

return builder.build();
}

return mGeofencePendingIntent;
}
#SuppressLint("MissingPermission")
private void setGeofences(){
GeofencingRequest geofencingRequest = getGeofencingRequest();
PendingIntent pi = getGeofencePendingIntent();
gfc.addGeofences(geofencingRequest, pi)
.addOnSuccessListener(this, new OnSuccessListener<Void>() {
#Override
public void onSuccess(Void aVoid) {
Log.d("Geofences", "geofencing set up succesfully");
Toast.makeText(MapsActivity.this, "Geofences set up", Toast.LENGTH_SHORT).show();

}
After some investigation I found I could recreate the 1000 error code with this code sample. It is based on this forum post: https://androidforums.com/threads/error-adding-geofence-on-android-8.1289302/
So to follow those directions (to fix - but I flipped them to recreate and then fix):
Use phone "Settings | Security & location | Location | Mode" - toggle between "High accuracy, Battery saving or Device only" until you get this prompt (the settings path will vary depending on android build):
In this example code - if you respond with "DISAGREE", the example code will generate the 1000 error code; if you repeat and respond with "AGREE" it will be successful in adding the geofence.
for android oreo to android S make sure to access setting high priority because geofence need that or it became error 1000
fun ceksetting(){

I am working with the google features to enable and disable location for the user, my main goal is, i enter the camera activity and it asks the user if he clicks cancel it goes back to the previous activity if everything fine it let the user take the photo.
This is my code:
`public class GoogleLocation extends Activity {
private static final int REQUEST_CHECK_SETTINGS = 5 ;
public static void displayLocationSettingsRequest(final Context context) {
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
.addApi(LocationServices.API).build();
googleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(10000 / 2);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
Log.i("location", "All location settings are satisfied.");
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
Log.i("location", "Location settings are not satisfied. Show the user a dialog to upgrade location settings ");
try {
// Show the dialog by calling startResolutionForResult(), and check the result
// in onActivityResult().
Log.d("HELLO2","HELLO2");
status.startResolutionForResult((Activity) context, REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
Log.i("location", "PendingIntent unable to execute request.");
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
Log.i("location", "Location settings are inadequate, and cannot be fixed here. Dialog not created.");
break;
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
Log.d("requestCode",String.valueOf(requestCode));
Log.d("resultCode",String.valueOf(resultCode));
if (requestCode == REQUEST_CHECK_SETTINGS) {
Log.d("ENTERED","ENTERED");
if(resultCode == RESULT_OK){
}
if(resultCode == RESULT_CANCELED){
Log.d("ENTERED","ENTERED");
this.finish();
}
}
}
}
`
i thaught that i can controll the dialog options 'ok' and 'cancel' with the onactivityresult, but as you guys can see inside the onactivity result i have 2 Log.d this just get fired when i pres the 'x' from the camera to close the camera, what is going on? i need to control the dialog but it is not working :/.
Any tip?
Thanks
use this function to enable location in high accuracy
public static void checkLocationSettings(final Activity context){
if(!LocationUtil.isLocationServicesAvailable(context)){
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(context)
.addApi(LocationServices.API).build();
googleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(10000 / 2);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
Log.e(TAG, "All location settings are satisfied.");
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
Log.e(TAG, "Location settings are not satisfied. Show the user a dialog to upgrade location settings ");
try {
// Show the dialog by calling startResolutionForResult(), and check the result in onActivityResult().
status.startResolutionForResult(context, REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
Log.e(TAG, "PendingIntent unable to execute request.");
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
Log.e(TAG, "Location settings are inadequate, and cannot be fixed here. Dialog not created.");
break;
}
}
});
}
use this function to check location is enabled with high accuracy
public static boolean isLocationServicesAvailable(Context context) {
int locationMode = 0;
boolean isAvailable = false;
if (Build.VERSION.SDK_INT > Build.VERSION_CODES.KITKAT){
try {
locationMode = Settings.Secure.getInt(context.getContentResolver(), Settings.Secure.LOCATION_MODE);
} catch (Settings.SettingNotFoundException e) {
e.printStackTrace();
}
isAvailable = (locationMode != Settings.Secure.LOCATION_MODE_OFF && locationMode == Settings.Secure.LOCATION_MODE_HIGH_ACCURACY);
}
return isAvailable;
}
if the user hit ok then the location will enable with high accuracy. else it will stay in the current state. if the location is already enabled and not in high accuracy, then it also the prompt will come to change location mode to high accuracy.
I know that the question about turning on/off GPS programatically on android has been discussed many times, and the answer is always the same:
"You can't for security/privacy reasons, you have to forward to location preferences screen and let the user enable/disable it."
I understand that, however I recently bought Tasker from the market and, among many other things that you can accomplish with it, you can set rules to auto-enable GPS on entering pre-determined applications and disable it on exit (see here for the tutorial on how to do it, and it just works!) and this app can't be signed with the firmware signing key as it works on many android versions and different devices and you don't even need to be rooted.
I would like to do this in my app. Of course, I don't want to blow up the users privacy, so I would first ask the user if he wants to turn it on automatically with the typical "remember my decision" checkbox and if he answers yes, enable it.
Does anybody have any idea or clue on how Tasker achieves this?
the GPS can be toggled by exploiting a bug in the power manager widget. see this xda thread for discussion.
here's some example code i use
private void turnGPSOn(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps")){ //if gps is disabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}
private void turnGPSOff(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider.contains("gps")){ //if gps is enabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}
use the following to test if the existing version of the power control widget is one which will allow you to toggle the gps.
private boolean canToggleGPS() {
PackageManager pacman = getPackageManager();
PackageInfo pacInfo = null;
try {
pacInfo = pacman.getPackageInfo("com.android.settings", PackageManager.GET_RECEIVERS);
} catch (NameNotFoundException e) {
return false; //package not found
}
if(pacInfo != null){
for(ActivityInfo actInfo : pacInfo.receivers){
//test if recevier is exported. if so, we can toggle GPS.
if(actInfo.name.equals("com.android.settings.widget.SettingsAppWidgetProvider") && actInfo.exported){
return true;
}
}
}
return false; //default
}

For all those still looking for the Answer:
Here is how OLA Cabs and other such apps are doing it.
Add this in your onCreate
if (googleApiClient == null) {
googleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).addConnectionCallbacks(this)
.addOnConnectionFailedListener(Login.this).build();
googleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(30 * 1000);
locationRequest.setFastestInterval(5 * 1000);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
// **************************
builder.setAlwaysShow(true); // this is the key ingredient
// **************************
PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi
.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(LocationSettingsResult result) {
final Status status = result.getStatus();
final LocationSettingsStates state = result
.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can
// initialize location
// requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied. But could be

// and check the result in onActivityResult().
status.startResolutionForResult(Login.this, 1000);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have
// no way to fix the
// settings so we won't show the dialog.
break;
}
}
});
}
These are the implmented methods:
#Override
public void onConnected(Bundle arg0) {
// TODO Auto-generated method stub
}
#Override
public void onConnectionSuspended(int arg0) {
// TODO Auto-generated method stub
}
#Override
public void onConnectionFailed(ConnectionResult arg0) {
// TODO Auto-generated method stub
}
Here is the Android Documentation for the same.
This is to help other guys if they are still struggling:
Edit: Adding Irfan Raza's comment for more help.
#Override protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if (requestCode == 1000) {
if(resultCode == Activity.RESULT_OK){
String result=data.getStringExtra("result");
} if (resultCode == Activity.RESULT_CANCELED) {
//Write your code if there's no result
}
}
}
ENABLE GPS:
Intent intent=new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
sendBroadcast(intent);
DISABLE GPS:
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", false);
sendBroadcast(intent);
This code works on ROOTED phones if the app is moved to /system/aps, and they have the following permissions in the manifest:
<uses-permission android:name="android.permission.WRITE_SETTINGS"/>
<uses-permission android:name="android.permission.WRITE_SECURE_SETTINGS"/>
Code
private void turnGpsOn (Context context) {
beforeEnable = Settings.Secure.getString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
String newSet = String.format ("%s,%s",
beforeEnable,
LocationManager.GPS_PROVIDER);
try {

str = "";
int j = 0;
for (int i = 0; i < list.length; i++) {
if (!list[i].equals (LocationManager.GPS_PROVIDER)) {
if (j > 0) {
str += ",";
}
str += list[i];
j++;
}
}
beforeEnable = str;
}
}
try {
Settings.Secure.putString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
beforeEnable);
} catch(Exception e) {}
}
Instead of using intent Settings.ACTION_LOCATION_SOURCE_SETTINGS you can directly able to show pop up in your app like Google Map & on Gps on click of ok button their is no need to redirect to setting simply you need to use my code as
Note : This line of code automatic open the dialog box if Location is not on. This piece of line is used in Google Map also

Since Android version 4.4, you can't enable/disable gps programatically. If you try the code proposed on this answer, an exception will be fired.
java.lang.SecurityException: Permission Denial: not allowed to send broadcast android.location.GPS_ENABLED_CHANGE
Above correct answer is very old it needs something new so Here is answer
As in last update we have androidx support so first include dependency in your app level build.gradle file
implementation 'com.google.android.gms:play-services-location:17.0.0'
then add in your manifest file:
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
don't forget to take user consent for these permissions if you are releasing
now here is code just use it
protected void createLocationRequest() {
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(5000);
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest);
SettingsClient client = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
#Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
// All location settings are satisfied. The client can initialize
// location requests here.
// ...
Toast.makeText(MainActivity.this, "Gps already open",
Toast.LENGTH_LONG).show();
Log.d("location settings",locationSettingsResponse.toString());
}
});
task.addOnFailureListener(this, new OnFailureListener() {
#Override
public void onFailure(#NonNull Exception e) {
if (e instanceof ResolvableApiException) {
// Location settings are not satisfied, but this can be fixed
// by showing the user a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
ResolvableApiException resolvable = (ResolvableApiException) e;
resolvable.startResolutionForResult(MainActivity.this,
REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException sendEx) {
// Ignore the error.
}
}
}
});
}
#Override
protected void onActivityResult(int requestCode, int resultCode, #Nullable Intent data) {
super.onActivityResult(requestCode, resultCode, data);
if(requestCode==REQUEST_CHECK_SETTINGS){
if(resultCode==RESULT_OK){
Toast.makeText(this, "Gps opened", Toast.LENGTH_SHORT).show();
//if user allows to open gps
Log.d("result ok",data.toString());
}else if(resultCode==RESULT_CANCELED){
Toast.makeText(this, "refused to open gps",
Toast.LENGTH_SHORT).show();
// in case user back press or refuses to open gps
Log.d("result cancelled",data.toString());
}
}
}

Short and easy solution with newest API, from https://developer.android.com/training/location/change-location-settings.html.
You will get nice Google AlertDialog with ok button without any need of going to settings.
Straight to the point. My code in Fragment:
override fun onResume() {
super.onResume()
checkGPSEnabled()
}
private fun checkGPSEnabled() {
val manager = requireContext().getSystemService(Context.LOCATION_SERVICE) as LocationManager
if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER).not()) {
turnOnGPS()
}
}
private fun turnOnGPS() {
val request = LocationRequest.create().apply {
interval = 2000
priority = LocationRequest.PRIORITY_HIGH_ACCURACY
}
val builder = LocationSettingsRequest.Builder().addLocationRequest(request)
val client: SettingsClient = LocationServices.getSettingsClient(requireActivity())
val task: Task<LocationSettingsResponse> = client.checkLocationSettings(builder.build())
task.addOnFailureListener {
if (it is ResolvableApiException) {
try {
it.startResolutionForResult(requireActivity(), 12345)
} catch (sendEx: IntentSender.SendIntentException) {
}
}
}.addOnSuccessListener {
//here GPS is On
}
}
That's it. Just copy and paste. You will need also:
implementation 'com.google.android.gms:play-services-location:18.0.0' and in Manifest <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
An answer was developed in another question, but it was closed, and I'd like the community to try it out as well.
boolean gpsStatus = locmanager.isProviderEnabled(LocationManager.GPS_PROVIDER);
if (!gpsStatus) {
Settings.Secure.putString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED, "network,gps");
}
See this comment
This solution would require the WRITE_SETTINGS and WRITE_SECURE_SETTINGS permissions.
Maybe with reflection tricks around the class android.server.LocationManagerService.
Also, there is a method (since API 8) android.provider.Settings.Secure.setLocationProviderEnabled
This is the best solution provided by Google Developers. Simply call this method in onResume of onCreate after initializing GoogleApiClient.
private void updateMarkers() {
if (mMap == null) {
return;
}
if (mLocationPermissionGranted) {
// Get the businesses and other points of interest located
// nearest to the device's current location.
mGoogleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API).build();
mGoogleApiClient.connect();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(10000);
locationRequest.setFastestInterval(10000 / 2);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest
.Builder()
.addLocationRequest(mLocationRequest);
PendingResult<LocationSettingsResult> resultPendingResult = LocationServices
.SettingsApi
.checkLocationSettings(mGoogleApiClient, builder.build());
resultPendingResult.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(#NonNull LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
final LocationSettingsStates locationSettingsStates = locationSettingsResult.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
// All location settings are satisfied. The client can
// initialize location requests here.
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
// Location settings are not satisfied, but this can be fixed
// by showing the user a dialog.
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(
MainActivity.this,
PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
} catch (IntentSender.SendIntentException e) {
// Ignore the error.
}
break;
case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
// Location settings are not satisfied. However, we have no way
// to fix the settings so we won't show the dialog.
break;
}
}
});
#SuppressWarnings("MissingPermission")
PendingResult<PlaceLikelihoodBuffer> result = Places.PlaceDetectionApi
.getCurrentPlace(mGoogleApiClient, null);
result.setResultCallback(new ResultCallback<PlaceLikelihoodBuffer>() {
#Override
public void onResult(#NonNull PlaceLikelihoodBuffer likelyPlaces) {
for (PlaceLikelihood placeLikelihood : likelyPlaces) {
// Add a marker for each place near the device's current location, with an
// info window showing place information.
String attributions = (String) placeLikelihood.getPlace().getAttributions();
String snippet = (String) placeLikelihood.getPlace().getAddress();
if (attributions != null) {
snippet = snippet + "\n" + attributions;
}
mMap.addMarker(new MarkerOptions()
.position(placeLikelihood.getPlace().getLatLng())
.title((String) placeLikelihood.getPlace().getName())
.snippet(snippet));
}
// Release the place likelihood buffer.
likelyPlaces.release();
}
});
} else {
mMap.addMarker(new MarkerOptions()
.position(mDefaultLocation)
.title(getString(R.string.default_info_title))
.snippet(getString(R.string.default_info_snippet)));
}
}
Note : This line of code automatic open the dialog box if Location is not on. This piece of line is used in Google Map also
status.startResolutionForResult(
MainActivity.this,
PERMISSIONS_REQUEST_ACCESS_FINE_LOCATION);
This code works on ROOTED phones:
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
String[] cmds = {"cd /system/bin" ,"settings put secure location_providers_allowed +gps"};
try {
Process p = Runtime.getRuntime().exec("su");
DataOutputStream os = new DataOutputStream(p.getOutputStream());
for (String tmpCmd : cmds) {
os.writeBytes(tmpCmd + "\n");
}
os.writeBytes("exit\n");
os.flush();
}
catch (IOException e){
e.printStackTrace();
}
}
}
For turning off GPS you can use this command instead
settings put secure location_providers_allowed -gps
You can also toggle network accuracy using the following commands:
for turning on use:
settings put secure location_providers_allowed +network
and for turning off you can use:
settings put secure location_providers_allowed -network
This one works for me.
It is a simpler solution than Rj0078's answer under this question, but that one is worked as well.
It shows a dialog like this:
(Written in Kotlin)
googleApiClient = GoogleApiClient.Builder(context!!)
.addApi(LocationServices.API).build()
googleApiClient!!.connect()
locationRequest = LocationRequest.create()
locationRequest!!.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
locationRequest!!.interval = 30 * 1000.toLong()
locationRequest!!.fastestInterval = 5 * 1000.toLong()
val builder = LocationSettingsRequest.Builder()
.addLocationRequest(locationRequest!!)
builder.setAlwaysShow(true)
result =
LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build())
result!!.setResultCallback { result ->
val status: Status = result.status
when (status.statusCode) {
LocationSettingsStatusCodes.SUCCESS -> {
// Do something
}
LocationSettingsStatusCodes.RESOLUTION_REQUIRED ->
try {
startResolutionForResult(),
status.startResolutionForResult(
activity,
REQUEST_LOCATION
)
} catch (e: SendIntentException) {
}
LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE -> {
// Do something
}
}
}
Things have changed since this question was posted, now with new Google Services API, you can prompt users to enable GPS:
https://developers.google.com/places/android-api/current-place
You will need to request ACCESS_FINE_LOCATION permission in your manifest:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
Also watch this video:
https://www.youtube.com/watch?v=F0Kh_RnSM0w
This is a more statble code for all Android versions and possibly for new ones
void checkGPS() {
LocationRequest locationRequest = LocationRequest.create();
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
SettingsClient settingsClient = LocationServices.getSettingsClient(this);
Task<LocationSettingsResponse> task = settingsClient.checkLocationSettings(builder.build());
task.addOnSuccessListener(this, new OnSuccessListener<LocationSettingsResponse>() {
#Override
public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
Log.d("GPS_main", "OnSuccess");
// GPS is ON
}
});
task.addOnFailureListener(this, new OnFailureListener() {
#Override
public void onFailure(#NonNull final Exception e) {
Log.d("GPS_main", "GPS off");
// GPS off
if (e instanceof ResolvableApiException) {
ResolvableApiException resolvable = (ResolvableApiException) e;
try {
resolvable.startResolutionForResult(ActivityMain.this, REQUESTCODE_TURNON_GPS);
} catch (IntentSender.SendIntentException e1) {
e1.printStackTrace();
}
}
}
});
}
And you can handle the GPS state changes here
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
if(requestCode == Static_AppVariables.REQUESTCODE_TURNON_GPS) {
switch (resultCode) {
case Activity.RESULT_OK:
// GPS was turned on;
break;
case Activity.RESULT_CANCELED:
// User rejected turning on the GPS
break;
default:
break;
}
}
}
You just need to remove the LocationListener from LocationManager
manager.removeUpdates(listener);
Use This code Simple and Easy to Access:
Permissions:
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
Follow this Code to access the GPS programmatically:
LocationManager locationManager ;
boolean GpsStatus ;
GPSStatus();
if(GpsStatus == true)
{
textview.setText("Your Location Services Is Enabled");
}else
{textview.setText("Your Location Services Is Disabled");}
Intent intent = new Intent(Settings.ACTION_LOCATION_SOURCE_SETTINGS);
startActivity(intent);
public void GPSStatus(){
locationManager = (LocationManager)context.getSystemService(Context.LOCATION_SERVICE);
GpsStatus = locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER);
}
I want my application to be able to enable/disable gps and mobile data programmatically as there are many apps like tasker, profile flow, lookout extra which can do this so I searched for it but not found any useful example I found the following code but they didn't work.
private void setMobileDataEnabled(Context context, boolean enabled) {
final ConnectivityManager conman = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
final Class conmanClass = Class.forName(conman.getClass().getName());
final Field iConnectivityManagerField = conmanClass.getDeclaredField("mService");
iConnectivityManagerField.setAccessible(true);
final Object iConnectivityManager = iConnectivityManagerField.get(conman);
final Class iConnectivityManagerClass = Class.forName(iConnectivityManager.getClass().getName());
final Method setMobileDataEnabledMethod = iConnectivityManagerClass.getDeclaredMethod("setMobileDataEnabled", Boolean.TYPE);
setMobileDataEnabledMethod.setAccessible(true);
setMobileDataEnabledMethod.invoke(iConnectivityManager, enabled);
}
private void turnGPSOn(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps")){ //if gps is disabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}
private void turnGPSOff(){
String provider = Settings.Secure.getString(getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider.contains("gps")){ //if gps is enabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
sendBroadcast(poke);
}
}
I want my application to be able to enable/disable gps
Fortunately, this is not possible, for obvious privacy reasons. While there were some hacks, like the one in your question, that used to work, those security flaws have since been fixed.
as there are many apps like tasker, profile flow, lookout extra which can do this
You are welcome to supply evidence that any of those apps can do this on modern versions of Android.
Try this for turning on gps
public void turnGPSOn()
{
Intent intent = new Intent("android.location.GPS_ENABLED_CHANGE");
intent.putExtra("enabled", true);
this.ctx.sendBroadcast(intent);
String provider = Settings.Secure.getString(ctx.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(!provider.contains("gps")){ //if gps is disabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
this.ctx.sendBroadcast(poke);
}
}
for turning off gps,
public void turnGPSOff()
{
String provider = Settings.Secure.getString(ctx.getContentResolver(), Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if(provider.contains("gps")){ //if gps is enabled
final Intent poke = new Intent();
poke.setClassName("com.android.settings", "com.android.settings.widget.SettingsAppWidgetProvider");
poke.addCategory(Intent.CATEGORY_ALTERNATIVE);
poke.setData(Uri.parse("3"));
this.ctx.sendBroadcast(poke);
}
}
For mobile data, did you added the permission in manifest? If not try adding and check it.
<uses-permission android:name="android.permission.CHANGE_NETWORK_STATE"/>
Let me know if everything worked.
