How to request Location Permission at runtime

Question

In the manifest file I added permissions coarse and fine, and when I run on device with Android 6, nothing happens! I try everything but no way to get location updates...

What am I doing wrong?

public class MainActivity extends AppCompatActivity implements LocationListener {

    LocationManager locationManager;
    String provider;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        locationManager = (LocationManager) getSystemService(Context.LOCATION_SERVICE);

        provider = locationManager.getBestProvider(new Criteria(), false);

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        Location location = locationManager.getLastKnownLocation(provider);

        if (location != null) {

            Log.i("Location Info", "Location achieved!");

        } else {

            Log.i("Location Info", "No location :(");

        }

    }


    @Override
    protected void onResume() {
        super.onResume();

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling
            //    ActivityCompat#requestPermissions
            // here to request the missing permissions, and then overriding
            //   public void onRequestPermissionsResult(int requestCode, String[] permissions,
            //                                          int[] grantResults)
            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        locationManager.requestLocationUpdates(provider, 400, 1, this);

    }

    @Override
    protected void onPause() {
        super.onPause();

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling

            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        locationManager.removeUpdates(this);

    }

    @Override
    public void onLocationChanged(Location location) {

        Double lat = location.getLatitude();
        Double lng = location.getLongitude();

        Log.i("Location info: Lat", lat.toString());
        Log.i("Location info: Lng", lng.toString());

    }

    @Override
    public void onStatusChanged(String provider, int status, Bundle extras) {

    }

    @Override
    public void onProviderEnabled(String provider) {

    }

    @Override
    public void onProviderDisabled(String provider) {

    }

    public void getLocation(View view) {

        if (ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED && ActivityCompat.checkSelfPermission(this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED) {
            // TODO: Consider calling

            // to handle the case where the user grants the permission. See the documentation
            // for ActivityCompat#requestPermissions for more details.
            return;
        }
        Location location = locationManager.getLastKnownLocation(provider);

        onLocationChanged(location);


    }

After having it defined in your manifest file, a friendlier alternative to the native solution would be using Aaper: https://github.com/LikeTheSalad/aaper like so:

@EnsurePermissions(permissions = [Manifest.permission.ACCESS_FINE_LOCATION])
private fun scanForLocation() {
    // Your code that needs the location permission granted.
}

Location permission privacy change in Android 10 or Android Q    We have to define additional ACCESS BACKGROUND LOCATION permission if user wants to access their current location in background so user needs to granted permission runtime also in requestPermission    If we are using lower than Android 10 device then ACCESS BACKGROUND LOCATION permission allow automatically with ACCESS FINE LOCATION or ACCESS COARSE LOCATION permission  This tabular format might be easy to understand what if we don t specify ACCESS BACKGROUND LOCATION in manifest file     AndroidManifest xml   lt uses-permission

Google has created a library for easy Permissions management. Its called EasyPermissions

Here is a simple example on requesting Location permission using this library.

public class MainActivity extends AppCompatActivity {

    private final int REQUEST_LOCATION_PERMISSION = 1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        requestLocationPermission();
    }

    @Override
    public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults);

        // Forward results to EasyPermissions
        EasyPermissions.onRequestPermissionsResult(requestCode, permissions, grantResults, this);
    }

    @AfterPermissionGranted(REQUEST_LOCATION_PERMISSION)
    public void requestLocationPermission() {
        String[] perms = {Manifest.permission.ACCESS_FINE_LOCATION};
        if(EasyPermissions.hasPermissions(this, perms)) {
            Toast.makeText(this, "Permission already granted", Toast.LENGTH_SHORT).show();
        }
        else {
            EasyPermissions.requestPermissions(this, "Please grant the location permission", REQUEST_LOCATION_PERMISSION, perms);
        }
    }
}

@AfterPermissionsGranted(REQUEST_CODE) is used to indicate the method that needs to be executed after a permission request with the request code REQUEST_CODE has been granted.

This above case, the method requestLocationPermission() method is called if the user grants the permission to access location services. So, that method acts as both a callback and a method to request the permissions.

You can implement separate callbacks for permission granted and permission denied as well. It is explained in the github page.

You need to actually request the Location permission at runtime  notice the comments in your code stating this    Here is tested and working code to request the Location permission   Be sure to import android Manifest   import android Manifest    Then put this code in the Activity   public static final int MY PERMISSIONS REQUEST LOCATION   99   public boolean checkLocationPermission         if  ContextCompat checkSelfPermission this              Manifest permission ACCESS FINE LOCATION                 PackageManager PERMISSION GRANTED                Should we show an explanation          if  ActivityCompat shouldShowRequestPermissionRationale this                  Manifest permission ACCESS FINE LOCATION                     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              new AlertDialog Builder this                       setTitle R string title location permission                       setMessage R string text location permission                       setPositiveButton R string ok  new DialogInterface OnClickListener                              Override                         public void onClick DialogInterface dialogInterface  int i                                  Prompt the user once explanation has been shown                             ActivityCompat requestPermissions MainActivity this                                      new String   Manifest permission ACCESS FINE LOCATION                                       MY PERMISSIONS REQUEST LOCATION                                                                         create                        show                else                  No explanation needed  we can request the permission              ActivityCompat requestPermissions this                      new String   Manifest permission ACCESS FINE LOCATION                       MY PERMISSIONS REQUEST LOCATION                     return false        else           return true            Override public void onRequestPermissionsResult int requestCode                                         String permissions    int   grantResults        switch  requestCode            case MY PERMISSIONS REQUEST LOCATION                   If request is cancelled  the result arrays are empty              if  grantResults length  gt  0                      amp  amp  grantResults 0     PackageManager PERMISSION GRANTED                        permission was granted  yay  Do the                    location-related task you need to do                  if  ContextCompat checkSelfPermission this                          Manifest permission ACCESS FINE LOCATION                             PackageManager PERMISSION GRANTED                           Request location updates                      locationManager requestLocationUpdates provider  400  1  this                                    else                       permission denied  boo  Disable the                    functionality that depends on this permission                             return                       Then call the checkLocationPermission   method in onCreate      Override protected void onCreate Bundle savedInstanceState        super onCreate savedInstanceState       setContentView R layout activity main                         checkLocationPermission        You can then use onResume   and onPause   exactly as it is in the question   Here is a condensed version that is a bit more clean    Override protected void onResume         super onResume        if  ContextCompat checkSelfPermission this              Manifest permission ACCESS FINE LOCATION                 PackageManager PERMISSION GRANTED             locationManager requestLocationUpdates provider  400  1  this             Override protected void onPause         super onPause        if  ContextCompat checkSelfPermission this              Manifest permission ACCESS FINE LOCATION                 PackageManager PERMISSION GRANTED             locationManager removeUpdates this
