    If using Eclipse, make sure that you don’t have multiple references to the maps.jar on your Project Build Path. This includes any direct reference to the maps.jar, or implicit reference through the Google APIs Library (Google APIs [Android 1.5]). In fact, only having the Google APIs Library on your Project Build Path should be sufficient.
