Answer 1

I have two webmethods: one for search in database and one for insert. I don't know if I'm connected to web service because my app exit when I press any button.

=> Because you are trying to make a network call directly on main UI thread. To resolve this issue, you need to implement AsyncTask.

And I would request you to check Logcat output at least which exactly gives you an error/exception log.
