How to implement mouse events in arm assembly in c for an android application

Question

I want to generate mouse events (like clicking and moving the pointer) in an android application. I made a lot of researchs about this kind of implementations and finally I found that it is the only way to do this from arm assembly level. I will use jni to call c routines and those c routines will have inline arm assembly codes. But I have a problem about using interrupts in arm processor that generates mouse events. I know that in intel chipsets, "int 33h" interrupt handles the mouse events. Can someone help me about mouse function interrupts in arm processor and how to use it.

Thanks.

I've implemented this and it's a bit tricky. I decided not to publish the app because there are too many "ifs" to make it work in a universal way. You will need to send the proper data to the correct /dev/device. The device name/number is different on each manufacturer and you will need to enumerate the devices and search for a match based on the name. It also requires that you run as a native linux app (not Java or NDK) with root privilege. Start by looking at how linux works with touch and mouse input.
