Android onRequestPermissionsResult grantResults size > 1

Question

After requesting permission, the ActivityCompat.OnRequestPermissionsResultCallback sometimes contains multiple grantResults, is it safe to just check the first one?

Answer 1

The shortest way you can make sure all the permissions are granted by the user.

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

    if (Arrays.binarySearch(grantResults, -1) >= 0) {

        /* Some permissions are not granted
        request permission again if required */

        return;
    }
}

The integer array that you can use to validate permissions :

if (Arrays.binarySearch(grantResults, -1) >= 0) { // some permissions are not granted }
