I have done a bit of research on HTML5 and started doing minor programming on Android. My questions is whether I should concentrate on HTML5 programming or Android. I understand that with HTML5 I should be able to write once and then port for any platform(Android, iOS, BB) but only with Android that is not the case.
Any advise, suggestions, comments are welcome.
May I recommend a very excellent session from Google I/O 2011:
