Re: [android-developers] Issue with startActivity

[YuviDroid]

You need to add the "test" activity into your manifest.

Anyway, use logcat to see the error that is being thrown, as Kostya
suggested.

Re: [android-developers] Issue with startActivity

[Kostya Vasilyev]

Did you add the new activity ("test") to the manifest?

What's in logcat?

BTW, you don't need to do your own try/catch blocks with error logging 
just to see what's going on. Just use logcat.
