Is there a reason you write all that code in the Activity Main instead of the B4XMainPage, which is the best place?

Hi Luca!
The RTP and the Location is there for testing proporses, I tryed to remove it and still giving me error.
IME must to be there on b4xpages.

I just found that

Sub Activity_CreatEMe(FirstTime As Boolean)

says "CreateEMe"

Fixed now, thanks to everyone!!!
