Answer 1

Kotlin code for check Permission & Fix this error: It's better to check size of IntArray with .isNotEmpty() in Kotlin.

 override fun onRequestPermissionsResult(
    requestCode: Int, permissions: Array<out String>,
    grantResults: IntArray
) {
    when (requestCode) {
        PERMISSIONS_REQUEST_PICK_IMAGE_GALLERY -> {
            if (grantResults.isNotEmpty()  &&  grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                choosePhotoFromGallary()
            } else  //Permission Denied
                //  toast("Permission must be granted in order to...")
        }
        PERMISSIONS_REQUEST_TAKE_PICTURE_CAMERA -> {
            if (grantResults.isNotEmpty() && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                takePhotoFromCamera()
            } else  //Permission Denied
                //  toast("Permission must be granted in order to ...")
        }
    } // when
} // fun

Documentation about permissions says

If request is cancelled, the result arrays are empty.

And it seems to be your situation, so you have to check first if the array is not empty:

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    switch (requestCode) {
        case REQUEST_CODE_ASK_LOCATION_PERMISSIONS:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // Permission Granted
                if (ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
                    mLastLocation = LocationServices.FusedLocationApi.getLastLocation(mGoogleApiClient);
                }
                startLocationUpdates();
            } else {
                // Permission Denied
            }
            break;
        default:
            super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    }
}
