cannot fetch location in marshmallow after giving permission request

问题:

I am developing an location app which is working fine in all devices except in Marshmallow.I have requested permission during runtime and when I grant permission longitude and latitude is not fetched,if i go to settings and change the location from high accuracy to battery saving,location is fetched and the app works.I want location to be fetched at high accuracy.

                   ActivityCompat.requestPermissions(this,             new String[]{                     Manifest.permission.CAMERA,                     android.Manifest.permission.ACCESS_FINE_LOCATION,                     android.Manifest.permission.ACCESS_COARSE_LOCATION,                     android.Manifest.permission.ACCESS_WIFI_STATE,                     Manifest.permission.INTERNET,                     Manifest.permission.WRITE_EXTERNAL_STORAGE,                     Manifest.permission.READ_PHONE_STATE,                     Manifest.permission.WAKE_LOCK,             },             1);

try this

step 1 :- add this permission in manifiesr file

 android.Manifest.permission.ACCESS_FINE_LOCATION,  android.Manifest.permission.ACCESS_COARSE_LOCATION, 

step 2 : ask runtime permission

 String permission = android.Manifest.permission.ACCESS_FINE_LOCATION;             if (ActivityCompat.checkSelfPermission(SearchCityClass.this, permission)                     != PackageManager.PERMISSION_GRANTED && ActivityCompat.                     checkSelfPermission(SearchCityClass.this, android.Manifest.permission.ACCESS_COARSE_LOCATION)                     != PackageManager.PERMISSION_GRANTED) {                 ActivityCompat.requestPermissions(SearchCityClass.this, new String[]                         {permission}, PERMISSION_GPS_CODE);              } 

step 3: handle permsiion result

 @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions,                                        @NonNull int[] grantResults) {     super.onRequestPermissionsResult(requestCode, permissions, grantResults);     if (requestCode == PERMISSION_GPS_CODE) {         if (grantResults[0] == PackageManager.PERMISSION_GRANTED) {               Toast.makeText(this, location_permission_granted_msg, Toast.LENGTH_SHORT).show();          } else {              Toast.makeText(this, location_permission_not_granted_msg, Toast.LENGTH_SHORT).show();         }     }  }

You have to give run time permission for android 6 like this

    if (ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_FINE_LOCATION) ==                     PackageManager.PERMISSION_GRANTED &&                     ContextCompat.checkSelfPermission(this, android.Manifest.permission.ACCESS_COARSE_LOCATION) ==                             PackageManager.PERMISSION_GRANTED) {                     // Permission already Granted                     //Do your work here //Perform operations here only which requires permission             } else {                 ActivityCompat.requestPermissions(this, new String[]{Manifest.permission.ACCESS_FINE_LOCATION, Manifest.permission.ACCESS_COARSE_LOCATION}, 1);             } 

and if permission is not already granted override onRequestPermission Results like this

    @Override     public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {             if (requestCode == 1) {                 if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {                             //Permission Granted                             //Do your work here //Perform operations here only which requires permission                 }             }         }

Add this code your Activity class

@Override protected void onCreate(Bundle savedInstanceState) {     super.onCreate(savedInstanceState);     setContentView(R.layout.activity_images);      requestLocationPermission();     //your other codes }  private void requestLocationPermission() {  if (ContextCompat.checkSelfPermission(this,  android.Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED &&                 ContextCompat.checkSelfPermission(this,                  android.Manifest.permission.ACCESS_COARSE_LOCATION) ==                 PackageManager.PERMISSION_GRANTED) {          } else {             ActivityCompat.requestPermissions(this, new String[]    {     Manifest.permission.ACCESS_FINE_LOCATION,      Manifest.permission.ACCESS_COARSE_LOCATION}, 1);     } }  @Override public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {      //Checking the request code of our request      //If permission is granted     if (requestCode == 1) {             if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {             //Displaying a toast             Toast.makeText(this, "Permission granted now you can get the location", Toast.LENGTH_LONG).show();              } else {             //Displaying another toast if permission is not granted             Toast.makeText(this, "Oops you just denied the permission", Toast.LENGTH_LONG).show();            } } 

Add this on your Mainfest XML

that's problem of permission

if (Build.VERSION.SDK_INT >= 23) {                  if (checkPermission(Manifest.permission.ACCESS_FINE_LOCATION, getActivity().getApplicationContext(), getActivity())) {                      if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {                         navigateToGoogleMap();                     } else {                         showSettingsAlert();                     }                 } else {                     requestPermission(Manifest.permission.ACCESS_FINE_LOCATION, PERMISSION_REQUEST_CODE, getActivity().getApplicationContext(), getActivity());                 }             } else {                  if (locationManager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {                     navigateToGoogleMap();                 } else {                     showSettingsAlert();                 }              }
