how to add permission in my sms manager

I'm very new to android studio and in my first app I want to build an sos app, my sos app specifically sends a message via sms with the current location. When I first built it, it only works on android 5.0 and down, it will not work in 6.0 and up and now I've tried to look at the logcat and the logcat says it needs a permission to send sms so I gave it a permission using the code below this paragraph and now it runs in android 6.0 but it's not sending messages... {if(checkselfpermission(Manifest.permission.SEND_SMS)==PackageManager.PERMISSION GRANTED);}
can you help me here is my manifest my file
<?xml version="1.0" encoding="utf-8"?>

I hope you can help me with this.

You can try this :-
Add it in Manifest -
<uses-permission android:name="android.permission.SEND_SMS" />
And use this runtime permission in your activity
ActivityCompat.requestPermissions(this,new String[]{Manifest.permission.SEND_SMS},1);

Again... Any help would be great! THANKS :D

As K. Sopheak said, it can take a while to get the location. From the documentation:
It may take a while to receive the first location update. If an immediate location is required, applications may use the getLastKnownLocation(String) method.
So, you could try getting the last known location using getLastKnownLocation(String) when the service is started and, assuming it exists, broadcast it in the same way you would a location update. Bear in mind, though, that the last known location could be out of date. Depending on what you're using the location for this may or may not be acceptable.
Also, as an aside, a couple of thoughts:
You said 3 seconds, but the code uses 2,000 milliseconds - was that just a typo?
The frequency of location updates is a minimum time - you are not guaranteed to get updates that often. As per the documentation:
The location update interval can be controlled using the minTime parameter. The elapsed time between location updates will never be less than minTime, although it can be more depending on the Location Provider implementation and the update interval requested by other applications.
Is there any particular reason you need location updates at such a high frequency? Obtaining a location can be battery intensive, particularly given that you are requesting FINE as well as COARSE location permissions, so requesting it so frequently could place an enormous drain on device battery life. This is particularly so given that the code is running in a service and will therefore continue to run even when the application is in the background or the user is in an activity which does not require location data. Again, from the documentation:
Choosing a sensible value for minTime is important to conserve battery life. Each location update requires power from GPS, WIFI, Cell and other radios. Select a minTime value as high as possible while still providing a reasonable user experience. If your application is not in the foreground and showing location to the user then your application should avoid using an active provider (such as NETWORK_PROVIDER or GPS_PROVIDER), but if you insist then select a minTime of 5 * 60 * 1000 (5 minutes) or greater. If your application is in the foreground and showing location to the user then it is appropriate to select a faster update interval.
Google recommends using the Google Play services location APIs instead of the Android framework location APIs:
The Google Play services location APIs are preferred over the Android framework location APIs (android.location) as a way of adding location awareness to your app. If you are currently using the Android framework location APIs, you are strongly encouraged to switch to the Google Play services location APIs as soon as possible.

Android WifiManager getScanResult complains Need ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission although declared permission

I am developing an App to check Wifi points.
I am getting error "java.lang.SecurityException: Need ACCESS_COARSE_LOCATION or ACCESS_FINE_LOCATION permission to get scan results" at wifiManager.getScanResults() even though I already declared those permissions.
main activity
public class MainActivity extends AppCompatActivity {

super.onCreate(savedInstanceState);

for (int i = 0; i < wifiScanList.size(); i++) {

I am on SDK 6.0
I observed similar question, but solution does not apply since I already declared permission.
Anyone know what might be problem? Thank you.

In Android M, you need to ask for the permission which is defined as dangerous in PermissionModel to the user before start using each time, it as such:
private boolean mayRequestLocation() {
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.M) {
return true;
}
if (checkSelfPermission(ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
return true;
}
if (shouldShowRequestPermissionRationale(ACCESS_FINE_LOCATION)) {
Snackbar.make(mView, R.string.permission_rationale, Snackbar.LENGTH_INDEFINITE)
.setAction(android.R.string.ok, new View.OnClickListener() {
#Override
#TargetApi(Build.VERSION_CODES.M)
public void onClick(View v) {
requestPermissions(new String[]{ACCESS_FINE_LOCATION}, REQUEST_FINE_LOCATION);
}
});
} else {
requestPermissions(new String[]{ACCESS_FINE_LOCATION}, REQUEST_FINE_LOCATION);
}
return false;
}
Add this to your Activity:
private static final int REQUEST_FINE_LOCATION=0
and load it during runtime with:
loadPermissions(Manifest.permission.ACCESS_FINE_LOCATION,REQUEST_FINE_LOCATION);
To evaluate the results of your permission request, you can override onRequestPermissionsResult method:
#Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
switch (requestCode) {
case REQUEST_FINE_LOCATION: {
// If request is cancelled, the result arrays are empty.
if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
// The requested permission is granted.
}
else{
// The user disallowed the requested permission.
}
return;
}
}

MADAO is right: you should turn on GPS to get the WIFI access point list.
But I'm not sure about PEERS_MAC_ADDRESS. If you look at the source code (line 957):
/**
* Return the results of the most recent access point scan, in the form of
* a list of {#link ScanResult} objects.
* #return the list of results
*/
public List<ScanResult> getScanResults(String callingPackage) {
enforceAccessPermission();
int userId = UserHandle.getCallingUserId();
int uid = Binder.getCallingUid();
boolean canReadPeerMacAddresses = checkPeersMacAddress();
boolean isActiveNetworkScorer =
NetworkScorerAppManager.isCallerActiveScorer(mContext, uid);
boolean hasInteractUsersFull = checkInteractAcrossUsersFull();
long ident = Binder.clearCallingIdentity();
try {
if (!canReadPeerMacAddresses && !isActiveNetworkScorer
&& !isLocationEnabled()) {
return new ArrayList<ScanResult>();
}
if (!canReadPeerMacAddresses && !isActiveNetworkScorer
&& !checkCallerCanAccessScanResults(callingPackage, uid)) {
return new ArrayList<ScanResult>();
}
if (mAppOps.noteOp(AppOpsManager.OP_WIFI_SCAN, uid, callingPackage)
!= AppOpsManager.MODE_ALLOWED) {
return new ArrayList<ScanResult>();
}
if (!isCurrentProfile(userId) && !hasInteractUsersFull) {
return new ArrayList<ScanResult>();
}
return mWifiStateMachine.syncGetScanResultsList();
} finally {
Binder.restoreCallingIdentity(ident);
}
}
The first if is checking canReadPeerMacAddresses which the code for checkPeersMacAddress() is:
/**
* Returns true if the caller holds PEERS_MAC_ADDRESS.
*/
private boolean checkPeersMacAddress() {
return mContext.checkCallingOrSelfPermission(
android.Manifest.permission.PEERS_MAC_ADDRESS) == PackageManager.PERMISSION_GRANTED;
}
If you add the permission you can bypass if (!canReadPeerMacAddresses && !isActiveNetworkScorer && !isLocationEnabled()) {. I've tested but I cannot get WIFI MAC list by just using the permission and disabling location.

ACCESS_FINE_LOCATION or ACCESS_COARSE_LOCATION is necessary. To get a valid result, you also have to turn on GPS or get a PEERS_MAC_ADDRESS permission like Setting.

Google Play Services - Activity Recognition Freezes After a Few Results

I have tried to simplify my code as much as possible, basically hte issue is that the ActivityRecognitionIntentService appears to be called a couple of times, then stalls out. It appears to be related to the requestCode in the PendingIntent, but I am not sure, can someone please advise me as to what is going wrong? Thanks.

Android location issue

Hi i am trying to get the device location using the Location api in android using the device network or wifi connection. However it doesnt seem to get the latt or longitude.
i have created a location provider and manager, and registered a location listener.
i then
launched
locationManagaer.requestLocationUpdates(locationProvide.getName(),TIME_INTERVAL, DISTANCE, this);
and from that point on, the app doesnt retrieve new location changes at all. what am i missing?
here is my userLocation Code
public class UserLocation implements LocationListener{
public static final int UPDATE_LATT = 0;
private static final int TIME_INTERVAL = 1000;
private static final int DISTANCE = 10;
private LocationManager locationManagaer;
private LocationProvider locationProvide;
private Handler mHandler;
public UserLocation(Context context, Handler handler){
locationManagaer = (LocationManager) context.getSystemService(Context.LOCATION_SERVICE);
locationProvide = locationManagaer.getProvider(LocationManager.NETWORK_PROVIDER);
mHandler = handler;
}
public void startSearchLocation(){
Log.d("", "sart location search");
locationManagaer.requestLocationUpdates(locationProvide.getName(),TIME_INTERVAL, DISTANCE, this);
}
#Override
public void onLocationChanged(Location location) {
Log.d("", "location update on " + location.getLongitude());
Message.obtain(mHandler,UPDATE_LATT, new Position(location.getLongitude(), location.getLatitude()));
}
#Override
public void onProviderDisabled(String provider) {
Log.d("", "onProviderDisabled");
}
#Override
public void onProviderEnabled(String provider) {
Log.d("", "onProviderEnabled");
}
#Override
public void onStatusChanged(String provider, int status, Bundle extras) {
Log.d("", "onStatusChanged");
}
}
here is my activity that uses this class to setup and listen for new locations
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mHandler = new Handler() {
#Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
super.handleMessage(msg);
position = (Position) msg.obj;
Toast.makeText(
getApplicationContext(),
position.getLattitude() + " " + position.getLongetude(),
Toast.LENGTH_LONG).show();
}
};
userLocation = new UserLocation(this, mHandler);
initializeViews();
userLocation.startSearchLocation();
}
Here is my position POJO
public class Position {
private double longetude;
private double lattitude;
public Position(){
}
public Position(double longetude, double lattitude){
}
public double getLongetude() {
return longetude;
}
public void setLongetude(double longetude) {
this.longetude = longetude;
}
public double getLattitude() {
return lattitude;
}
public void setLattitude(double lattitude) {
this.lattitude = lattitude;
}
}
Here is part of my manifest file
<application
android:allowBackup="true"
android:icon="#drawable/ic_launcher"
android:label="#string/app_name"
android:theme="#style/AppTheme" >
<activity
android:name="com.jr.haliotest.MainActivity"
android:label="#string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />

Testing on a htc one x thats rooted if that helps. wifi is on and god signal

If you are within a building then it is probably that your device is not able to connect to a GPS Provider. I would suggest if you move to a more open space so that you can get a signal.
One hint that if the device is connected to receive a gps signal. The sign of the gps will stop blinking and will become solid.

I would start by checking if your phones location services are enabled and maybe try rebooting. Also try using "GPS" instead of "network" to see if the problem is related to your network not providing location info.
From my experience wifi networks will sometimes simply not provide location info. I'm not sure if that's also true for cell networks, but I suspect there is no guarantee.
