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.
Manifest permission:

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.INTERNET"/>

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.:
public class MapsActivity extends FragmentActivity implements OnMapReadyCallback, GoogleApiClient.ConnectionCallbacks,
GoogleApiClient.OnConnectionFailedListener, LocationListener, ActivityCompat.OnRequestPermissionsResultCallback {

Geofence.GEOFENCE_TRANSITION_ENTER | Geofence.GEOFENCE_TRANSITION_EXIT).build());

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

In one of my activity I am showing google map in fragment. It's working fine with 3g or high speed internet connection. But in 2g or very slow internet connection it's hang my mobile, And after some time I get 'not responding' message. Is there any way by which i can handle this situation?
here's the code
#Override
protected void onCreate(Bundle savedInstanceState) {
try {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_maps);
// Obtain the SupportMapFragment and get notified when the map is ready to be used.
SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager()
.findFragmentById(R.id.map);
mapFragment.getMapAsync(this);
InitializeClient();
InitializeDB();
} catch (Exception e) {
e.printStackTrace();
}
mqtt=new MQTT();
try{
if(ip==null){
System.out.println("Mqtt Initialized in Maps Activity");
ip="demo.aiotm.in:1883";
}
//mqtt.setHost("tcp://"+ip);
mqtt.setHost("tcp://10.30.60.242:1883");
connection = mqtt.blockingConnection();
connection.connect();
}catch (Exception e){
e.printStackTrace();
}
}
private void InitializeClient() {
try {
//Initializing googleApiClient
googleApiClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
googleApiClient.connect();
}catch (Exception e){e.printStackTrace();}
if (this.mMap != null) {

return;
}else {System.out.println(":::::::::::::::::::::::::::::::::: Map Not Initialized :::::::::::::::::::::::::::::::::::::::::;");}
mMap.setMyLocationEnabled(true);
}
if (googleApiClient.isConnected()||googleApiClient.isConnecting()){System.out.println("------------------------------------>Api is connecting<-----------------------------------");}
}
the above is my initialization code for maps activity..!!, i hope this much code is enough
NOTE:- It's not a full code. I removed some of code for security reason.
getMapAsync() provides a callback onMapReady where you receive the googleMap.
On slow internet connection maybe it takes time to query the maps, so you can move the googleApiClient initialization in onMapReady callback and also the permission requests.
Your code should look something like this
#Override
public void onMapReady(GoogleMap googleMap) {
mGoogleMap = googleMap;
LatLngBounds SINGAPORE = new LatLngBounds(new LatLng(1.2729, 103.6066), new LatLng(1.3553, 104.0323));
mGoogleMap.setLatLngBoundsForCameraTarget(SINGAPORE);
mGoogleMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
mGoogleMap.setPadding(0, 0, 16, 500);
//Initialize Google Play Services
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
if (ContextCompat.checkSelfPermission(getContext(), Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
//Location Permission already granted
mGoogleMap.setMyLocationEnabled(true);
} else {
//Request Location Permission
checkLocationPermission();
}
} else {
mGoogleMap.setMyLocationEnabled(true);
}
getGoogleApiClient();
LocationRequest locationRequest = LocationRequest.create();
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
builder.setAlwaysShow(true);
final PendingResult<LocationSettingsResult> result = LocationServices.SettingsApi.checkLocationSettings(mGoogleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(#NonNull LocationSettingsResult locationSettingsResult) {
final Status status = locationSettingsResult.getStatus();
final LocationSettingsStates state = locationSettingsResult.getLocationSettingsStates();
switch (status.getStatusCode()) {
case LocationSettingsStatusCodes.SUCCESS:
//All location settings are satisfied
displayMarker();
break;
case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:
//Location settings are not satisfied, but could be fixed by showing a dialog
try {
//Show the dialog by calling startResolutionForResult(), and check the result in onActivityResult()
status.startResolutionForResult(getActivity(), FragmentSearchLocation.LOCATION_SETTINGS);
} catch (IntentSender.SendIntentException e) {
e.printStackTrace();
}
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;
}
}
});
}
Could explain me plaese how i should explain to user permission
i work with Camera2API and i implement such snippet of code to ask permishion dinamicly
private void openCamera(int width, int height) {
setUpCameraOutputs(width, height);
CameraHelper.configureTransform(width, height, textureView, previewSize, getActivity());
CameraManager manager = (CameraManager) getSystemService(Context.CAMERA_SERVICE);
try {
if (!cameraOpenCloseLock.tryAcquire(2500, TimeUnit.MILLISECONDS)) {
throw new RuntimeException("Time out waiting to lock camera opening.");
}
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) !=
PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) {
// Show an explanation to the user *asynchronously* -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
} else {
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(
getActivity(), new String[]{android.Manifest.permission.CAMERA},
MY_PERMISSIONS_REQUEST);
// MY_PERMISSIONS_REQUEST is an
// app-defined int constant. The callback method gets the
// result of the request.
}
}
manager.openCamera(mCameraId, mStateCallback, mBackgroundHandler);
} catch (CameraAccessException e) {
e.printStackTrace();
} catch (InterruptedException e) {
throw new RuntimeException("Interrupted while trying to lock camera opening.", e);
}
}
according to google docks i should check if user deny permission before
there is method which return true of false
shouldShowRequestPermissionRationale();
and according google
This method returns true if the app has requested this permission previously and the user denied the request.
if i understand correctly according google comments inside this method implementation
// Show an explanation to the user asynchronously -- don't block
// this thread waiting for the user's response! After the user
// sees the explanation, try again to request the permission.
And finally for example user deny my permission before and next time when he go to my screen with camera app should create the my castom pop-up with explanation "Please agree this permishion if you want to continue" and for example user agree this time and i should recall this method again according this
// sees the explanation, try again to request the permission.
but this method
shouldShowRequestPermissionRationale();
return to me true again, because it didn't know about the user intent to agree with permission.
Could you explain me please how to make it properly way? Maybe you have example?
Eventually i find a solution with help of #nuuneoi, thanks a lot!
And implement it like this
public void camera(View view) {
toCamera();
}
private void toCamera() {
if (!isCheckPermission()){
return;
}
if (isProcessWasFinish()) {
startActivity(new Intent(getApplicationContext(), CameraActivity.class));

} else {
startActivity(new Intent(getApplicationContext(), UserDataScreen.class));
overridePendingTransition(R.anim.open_next, R.anim.close_main);
}
}
private boolean isCheckPermission() {
if (ActivityCompat.checkSelfPermission(this, Manifest.permission.CAMERA) !=
PackageManager.PERMISSION_GRANTED) {
// Should we show an explanation?
if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CAMERA)) {
showMessageOKCancel("You need to allow access to Camera");
return false;
}
// No explanation needed, we can request the permission.
ActivityCompat.requestPermissions(this, new String[]{android.Manifest.permission.CAMERA},
MY_PERMISSIONS_REQUEST);
return false;
// MY_PERMISSIONS_REQUEST is an
// app-defined int constant. The callback method gets the
// result of the request.
}
return true;
}
private void showMessageOKCancel(String message) {
new AlertDialog.Builder(MainActivity.this)
.setMessage(message)
.setPositiveButton("OK", listener)
.setNegativeButton("Cancel", listener)
.create()
.show();
}
DialogInterface.OnClickListener listener = new DialogInterface.OnClickListener() {
final int BUTTON_NEGATIVE = -2;
final int BUTTON_POSITIVE = -1;
#Override
public void onClick(DialogInterface dialog, int which) {
switch (which) {
case BUTTON_NEGATIVE:
// int which = -2
dialog.dismiss();
break;
case BUTTON_POSITIVE:
// int which = -1
ActivityCompat.requestPermissions(
MainActivity.this, new String[]{android.Manifest.permission.CAMERA},
MY_PERMISSIONS_REQUEST);
dialog.dismiss();
break;
}
}
};
#Override
public void onRequestPermissionsResult(int requestCode, #NonNull String[] permissions,
#NonNull int[] grantResults) {
switch (requestCode) {
case MY_PERMISSIONS_REQUEST: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0
&& grantResults[0] == PackageManager.PERMISSION_GRANTED) {
Log.e(MY_LOG, "Camera permission Granted");
// permission was granted, yay! Do the
// contacts-related task you need to do.
toCamera();
} else {
Log.e(MY_LOG, "Camera permission Denied");
// permission denied, boo! Disable the

}
}
default: {

}
}
Hey you can use some of the libraries that are great for asking user permissions on app launch.
There's a great library to help you do that in Android :
Github link for the Permission dispatcher library
You can find the usage examples of the permission dispatcher library here
You can also check these libraries :
App-Runtime-Permissions-Android

MarshmallowPermissionManager
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
}
All these answers are not allowed now. Here is the correct one:
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
// fixed by showing the user
// a dialog.
try {
// Show the dialog by calling
// startResolutionForResult(),
// 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 {
Settings.Secure.putString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED,
newSet);
} catch(Exception e) {}
}
private void turnGpsOff (Context context) {
if (null == beforeEnable) {
String str = Settings.Secure.getString (context.getContentResolver(),
Settings.Secure.LOCATION_PROVIDERS_ALLOWED);
if (null == str) {
str = "";
} else {
String[] list = str.split (",");
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
public class MainActivity extends AppCompatActivity

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 am trying to create an app for my own use that enables/disables certain features like WiFi, GPS, etc; my question pertains to GPS. Note that my phone is not rooted and I would like to keep it that way.
I have successfully enabled GPS using the following code:
public void toggleGPS() {
GoogleApiClient googleApiClient = new GoogleApiClient.Builder(this)
.addApi(LocationServices.API)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.build();
LocationRequest locationRequest = new LocationRequest();
if (isGPSEnabled()) {
locationRequest.setPriority(LocationRequest.PRIORITY_BALANCED_POWER_ACCURACY);
locationRequest.setInterval(60 * 60 * 1000);
locationRequest.setFastestInterval(60 * 60 * 1000);
} else {
locationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
locationRequest.setInterval(1000);
locationRequest.setFastestInterval(1000);
}
googleApiClient.connect();
LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder().addLocationRequest(locationRequest);
PendingResult<LocationSettingsResult> result =
LocationServices.SettingsApi.checkLocationSettings(googleApiClient, builder.build());
result.setResultCallback(new ResultCallback<LocationSettingsResult>() {
#Override
public void onResult(LocationSettingsResult result) {
Status status = result.getStatus();
LocationSettingsStates locationSettingsStates = result.getLocationSettingsStates();
if (status.getStatusCode() == LocationSettingsStatusCodes.RESOLUTION_REQUIRED) {
try {
// Show the dialog by calling startResolutionForResult(),
// and check the result in onActivityResult().
status.startResolutionForResult(MainActivity.this, REQUEST_CHECK_SETTINGS);
} catch (IntentSender.SendIntentException e) {
}
}
}
});
}
So when GPS isn't on, this code prompts me to turn it on, as I want. However, it doesn't seem to shut off when I request Balanced Power and set the larger intervals and no other app is using GPS. I assumed that if my app no longer needs high accuracy, then GPS will automatically be switched off. Am I misunderstanding something? And is there any way to switch it off? I can sort of understand the security concerns for disallowing GPS to be ENABLED programmatically, but I don't understand why Android wouldn't allow it to be DISABLED.
Thanks in advance!
try this code it works on all versions, make a try ....
// automatic turn off the 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);
}
}
and code to enable is as follow you can use this..
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);
}
}
