Fixed bug 2266 - please add notifications for clipboard updates on Android 

Sylvain

Hi! here's a patch for that with two class loaded regarding API level.
Test both case : before API 11 and after.

I also remove now unused GetSystemServiceFromUIThread() and minor clean-up (haptic warning prototype).
