Check Android Permissions in a Method

Question

here is my code and it works perfectly fine.

if (ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED || ActivityCompat.checkSelfPermission(activity, Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED) {
    mMap.setMyLocationEnabled(true);
}

But I don't like such a big code on every check, and want to delegate it to a method in my utility class.

if (Utils.hasMapLocationPermissions(getActivity())) {
    mMap.setMyLocationEnabled(true);
}

But setMyLocationEnabled has annotation @RequiresPermission And thus I can't delegate it to a method, because lint and editor shows it as an error.

Is there some annotation to write on my utility method and suppress lint?

Something like this

@ChecksPermission
public boolean hasMapLocationPermissions(Activity activity) {
  return // my checking logic..
}

Try putting `setMyLocationEnabled` in a `try-catch` and handle `SecurityException`. Should work without annotation. — Rohit5k2, Mar 16 '16 at 10:12
The code is still big and looks ugly. I want to solve with neat small code. — Ioane Sharvadze, Mar 18 '16 at 07:08

You can rename your method such as checkLocationPermission(Activity activity). I´ve discovered that your method's name must start with "check" and end with "Permission" to pass Lint warnings.

For example:

public static boolean checkLocationPermission(Context context) {
    return ActivityCompat.checkSelfPermission(context,
            Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED
            && ActivityCompat.checkSelfPermission(context,
            Manifest.permission.ACCESS_COARSE_LOCATION) == PackageManager.PERMISSION_GRANTED;
}

For me only the `checkPermission()` method name works. – Wojtek Jan 04 '19 at 09:11

You can suppress this error in both the editor and in lint reports by annotating your method with @SuppressWarnings("MissingPermission"), or you can suppress the error for just a single statement by putting //noinspection MissingPermission above that line.

For example:

@SuppressWarnings("MissingPermission")
public boolean hasMapLocationPermissions(Activity activity) {
  // your checking logic
}

Or:

if (Utils.hasMapLocationPermissions(getActivity())) {
    //noinspection MissingPermission
    mMap.setMyLocationEnabled(true);
}
