Testing AppMessage delay, Android side

public void receiveData(final Context context, final int transactionId, final PebbleDictionary data)
    {
        PebbleKit.sendAckToPebble(context, transactionId);

        PebbleDictionary out = new PebbleDictionary();
        out.addInt8(0, (byte) 0); //I can't send empty dictionary from Android for some reason so I need to include this.

        PebbleKit.sendDataToPebble(context, myUUID, out);
    }
