I want to test some 3rd party application for which I have "NO" sourcecode. Like Facebook, youtube etc. Therefore I want to create my own app, service, background app or etc etc in Android, which can send keystrokes to this thirdparty application.

We tried to test the facebook but unable to inject keyevents to other activities like Camera or Gallery.

False solution:
Robotium allows to run test on only one application for one project, and the applications to be tested should have the "same signature" as the developed application. "But remember we don't have the signature of facebook."


Monkey Script: We also tried monkey scripts but in monkey script we can send only low level events to the android applications like dispatchkeyevent, dispatchpointerevent etc.
Also monkey works when we connect the android device to computer with usb cable and fire the monkey command using command prompt. "We do NOT want any usb cable, or computer solution. We have to create app."

This is NOT a project, we need solution. ONLY bid, If you have solution, I will pay rightaway.
