Re: [AD] Ouya controller support

[Jonathan Lilliemarck <jonathan.lilliemarck@xxxxxxxxxx>]

The Linux Joystick driver pretty much works as it is! It's just a few defines in linux/input.h that are missing. At first I got error EACCES when the driver opened the device but adding <uses-permission android:name="tv.ouya.DIRECT_INPUT_ACCESS"/> to the manifest solved it!

The adb shell has a tool getevent that can be used to examine the device in various ways:

shell@xxxxxxxxxx:/ $ getevent -lp /dev/input/event1                               

add device 1: /dev/input/event1

The /dev/input/event/* API should work, but perhaps it emits key and joystick events in a range that the new Linux joystick driver is currently ignoring. We're using some heuristics to determine if the input device is a joystick or not but they are not 100% certain. If you could run a tool like evtest, that would be perfect.
