+## How do I debug whats happening?
+
+If you are running on Android, then all verbose logs are dispatched to logcat, you can see internal working by:
+
+```bash
+$ adb logcat | grep android_touch
+```
+
+For example following is the debug output in logcat for below command:
+
+```bash
+$ curl -d '[{"type":"down", "contact":0, "x": 100, "y": 100, "pressure": 50}, {"type": "commit"}, {"type": "up", "contact": 0}, {"type": "commit"}]' http://localhost:8080
