Check Android Permissions in a Method

问题

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..
}

回答1:

You can rename your method 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;
}

回答2:

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);
}
