deviceID := C.AInputEvent_getDeviceId(e)
if deviceID == 0 {
// Software keyboard input, leaving for scribe/IME.
return
}
k := key.Event{
Rune: rune(C.getKeyRune(env, e)),
Code: convAndroidKeyCode(int32(C.AKeyEvent_getKeyCode(e))),
}
switch C.AKeyEvent_getAction(e) {
case C.AKEY_STATE_DOWN:
k.Direction = key.DirPress
case C.AKEY_STATE_UP:
k.Direction = key.DirRelease
default:
