Runtime Permission on android marshmallow

Question

I would like to know whether the runtime permission popup is visible or not in the activity. How can i know that? Is there any callback or overrided method for the same.

You request permissions yourself so you know when it is shown. You can also add a result callback. See the code below;

public void requestPermissions(List<String> permissions, ActivityCompat.OnRequestPermissionsResultCallback onRequestPermissionsResultCallback) {
    String[] params = permissions.toArray(new String[permissions.size()]);
    requestPermissions(params, onRequestPermissionsResultCallback);
}

public void requestPermissions(String[] permissions, ActivityCompat.OnRequestPermissionsResultCallback onRequestPermissionsResultCallback) {
    this.onRequestPermissionsResultCallback = onRequestPermissionsResultCallback;
    ActivityCompat.requestPermissions(this, permissions, REQUEST_CODE_PERMISSIONS);
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    if (requestCode == REQUEST_CODE_PERMISSIONS && onRequestPermissionsResultCallback != null) {
        this.onRequestPermissionsResultCallback.onRequestPermissionsResult(requestCode, permissions, grantResults);
        this.onRequestPermissionsResultCallback = null;
    }
}

This would generally sit inside some kind of base Activity class.
