If I understand the question correctly, you want to determine, at runtime, whether GOogle Maps exists on the device, and take an alternative path if it does not.

you must build your app with Google Maps API, but set the required flag to "false" in your manifest

<uses-library android:name="com.google.android.maps" android:required="false" />

use code like this to determine if the library exists on the device

try {

   mContext.getClassLoader().loadClass("com.google.android.maps.MapView");

   // You have Google Maps

}

catch (ClassNotFoundException e)

{   

 // No Google Maps

}
