Question

anybody knows what can be the reason for when i start a service from an Activity, the emulator shows a message “the activity is not responding?”

Inside my Service i start 2 threads in order to make some tasks. can be this the cause of the problem?

Thanks

Because something in your application — the activity, the service, etc. — is tying up the main application thread.

Not directly, no, though you really should consider using AsyncTask rather than forking your own threads

Doing long-running work on the main application thread, or tying it up with a sleep() or busy-loop, will cause this exception.
