Google Maps Android API V2 check if GoogleMaps are installed on device

This type of questions arise at the time of shift from google map v1 to v2. And for v2 we need some settings as well as v2 not running in emulator because Google Play service is missing in emulator.
This is very helpful for me.

Android app not run in debug mode and showing “Waiting for Debugger” message?

Some devices will only let the debugger attach if the application has the android.permission.SET_DEBUG_APP permission set in its manifest file:

<manifest>
  <uses-permission android:name="android.permission.SET_DEBUG_APP"/>

</manifest>
