In order for the Android input system to correctly work you should report
BTN_TOUCH events to Android. On L4Re the L4Linux fb driver has the option
l4fb.touchscreen which results in the fb driver implicitly converting BTN_LEFT
events into BTN_TOUCH.

However, the best way is, if the (native) input driver conforms to Linux's
multitouch protocol.

Best,
Matthias.
