I'm trying to implement askForPermisions function as an Adobe Native Extension (ANE) for AIR. My function is now defined as:

public class APKaskForPermission implements FREFunction  {
    public static final String TAG = "askForPermission";
    @Override
    public FREObject call(FREContext ctx, FREObject[] passedArgs) {
        FREObject result = null;
        String permission;
        Integer requestCode;

        try{
            permission = passedArgs[0].getAsString();
            requestCode = passedArgs[1].getAsInt();

            if (ContextCompat.checkSelfPermission(NativeExtension.appContext, permission) != PackageManager.PERMISSION_GRANTED) {

                // Should we show an explanation?
                if (ActivityCompat.shouldShowRequestPermissionRationale(ctx.getActivity(), permission)) {
                    Log.d(TAG, "shouldShowRequestPermissionRationale: " + permission);
                    //This is called if user has denied the permission before
                    //In this case I am just asking the permission again
                    Log.d(TAG, "requestPermissions: " + permission);
                    ActivityCompat.requestPermissions(ctx.getActivity(), new String[]{permission}, requestCode);

                } else {
                    Log.d(TAG, "requestPermissions: " + permission);
                    ActivityCompat.requestPermissions(ctx.getActivity(), new String[]{permission}, requestCode);
                }
                result = FREObject.newObject(false);
            } else {
                Log.d(TAG, "" + permission + " is already granted.");
                //Toast.makeText(this, "" + permission + " is already granted.", Toast.LENGTH_SHORT).show();
                result = FREObject.newObject(true);
            }
        } catch (Exception e) {
            e.printStackTrace();
            return null;
        }

        return result;
    }
}

This display the dialog as expected, but I cannot find what to do to get the response, as all examples on the web define it in the MainActivity source, but I'm in the native extension context.

Any help?
