Adding custom frameworks in android

Question

I'm making a root access app which generates touch event from the background. Generating touch events requires INJECT_EVENTS permission which is actually a Signature level permission. Since I cannot have the same signature as the ROM so I thought of two solutions as of now :

1. Create a .jar class out of a class which actually generates the touch event and call the method of this class from my app and pass coordinates as the arguments. And then push this jar file to /system/framework/

2. The second thing which I thought of was to inject the above created class inside the framework.jar only and then call the method of the class.

I wanted to ask which of the solution might work or if anyone has another idea in their mind, it would be great.

Answer 1

It might work on system/framework , I'm uncertain. You can also try this, http://allmydroids.blogspot.de/2014/04/android-system-platform-signed.html
