Google Map Doesn't Load Into My App Device

I am newbie to android development. I am learning on my own using internet and following tutorials. I am making an app which have 3 tabs, one is for location second is for camera a

Solution 1:

For the Android Version >= M, the permission has to be asked at Runtime, which can not be done automatically. A general Runtime Permission asking code. Use getActivity() if inside Fragment instead of this.

@OverridepublicvoidonMapReady(GoogleMap googleMap) {


        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
        if(ActivityCompat.checkSelfPermission
                (this, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED
                &&
                ActivityCompat.checkSelfPermission
                        (this, Manifest.permission.ACCESS_COARSE_LOCATION) != PackageManager.PERMISSION_GRANTED)
        {
            requestPermissions(newString[]{
                    Manifest.permission.ACCESS_COARSE_LOCATION,
                    Manifest.permission.ACCESS_FINE_LOCATION
            }, 1);
            //return;
        }
     else{
        googleMap.setMyLocationEnabled(true);

        LatLngloc=newLatLng(31.492370,74.329060);

        googleMap.addMarker(newMarkerOptions().position(loc).title("I am here"));

        // For zooming automatically to the location of the markerCameraPositioncameraPosition=newCameraPosition.Builder().target(loc).zoom(12).build();
        googleMap.animateCamera(CameraUpdateFactory.newCameraPosition(cameraPosition));
      }
    }

Handle permission:

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

            case1:
                if (grantResults[0] != PackageManager.PERMISSION_GRANTED){
                    // permission not granted
                }
                else {
                    // permission granted
                }
                break;
            //default://super.onRequestPermissionsResult(requestCode, permissions, grantResults);
        }
    //}
}
