This code is not working.I am a beginner to android and I think this should have worked.Please help..I am not getting an errors.My screen just goes black.
Where exactly is the problem in this code???

Answer 1

The fact that you’re using an infinite loop might be the problem. In fact I can’t think of many cases when infinite loops aren’t problems.
Anyway it appears that your loop iterates once through the first if block of

if(watsUp1==true){

and then in that block you set watsUp1 = false, which wouldn’t be a problem except you’re in the infinite loop.

Also I would just work on making your code more aesthetically pleasing in the future.
