Timeout when running APK on emulator

I'm having problems when running emulator on Eclipse ADT . When running APK , it only gives timeout , even increasing ADB time to 50000 for example. The project runs right on the phone, only in the emulator that does not (already tried up in Genymotion , to no avail). Does anyone know a solution?

After timeout , this occurs:

  

New package not yet registered with the system. Waiting 3 seconds before next attempt.

Then:

The manifest is like this:
