The keys on the controller are:

100 = Y
 97 = A
Comment 1 Martin Gerhardy 2013-11-24 10:13:34 UTC 
i really wonder why this happens, as they see them handled in keycode_to_SDL

but it looks like my actions did not go through Android_OnPadDown/-Up.

i added the line
__android_log_print(ANDROID_LOG_ERROR,"myown","android pad down %i", keycode); into these functions and don't see any output in the logcat.

Can you debug what happens on the Java side?
Comment 3 Martin Gerhardy 2013-11-26 12:55:20 UTC 
It looks like this is somehow connected with having the xbox 360 controllers connected to the ouya. I wasn't able to debug it further, yet. But as soon as I plug in the xbox controller (getting all 4 slots) and after that the ouya controller. I get weird results.

I still get events for not opened joysticks for example. Maybe that is related to the issue that the keys are reported to be unknown.
Comment 4 Gabriel Jacobo 2013-11-26 16:07:27 UTC 
It seems that this can be a side effect of plugging in a controller after initializing the joystick list on the java side.

In SDLActivity.java, onKey function, if SDLActivity.getJoyId( event.getDeviceId() ) is -1, the key will be passed to the keyboard code even if it actually is a gamepad event.
Comment 5 Sam Lantinga 2013-11-27 08:10:36 UTC 
FWIW, SDL 2.0 supports hot-plug joysticks, so this is something that would be nice if it worked on Android.
Comment 6 Martin Gerhardy 2014-01-25 13:48:20 UTC 
I think this can be closed now. since the hotplugging support is in, it doesn't happen anymore.
