mouse support for android (non nvidia shield)

[GoogleCodeExporter]

Hi, I first want to thank you for making an amazing port, it's by far the best 
Android release of mame that I've tried.

I have an Android development board (a Firefly-RK3288) which runs mame4droid 
(using 1.9.2). This board supports both mouse and keyboard via USB, however 
when running mame4droid the mouse merely acts as a touch pointer, and doesn't 
work in the games as a mouse/spinner. I've tried enabling the nvidia shield 
extensions yet the mouse is still not enabled/used (it just acts like an 
Android touch/pointer).

After looking at the code I can see that the nvidia shield mouse extensions 
appear to be specific to the nvidia shield sdk (no surprise). Can you tell me 
what would be needed to add similar support for mice on other platforms (such 
as the Firefly-RK3288)? Note that there's nothing special about the mouse on 
the Firefly-RK3288, it's merely a USB mouse that appears as a touch pointer in 
Android.

I'm an experienced C/C++ programmer so I don't mind doing the work, yet I need 
some guidance as I have little Android/Java experience.

Thanks!

You cant. Regular android has not relative mouse input api.

 If you really want to add mouse input you should root your device and read event from /dev/input queues. That's why I'm using nvidia extensions and I haven't added mouse support for regular android devices.
