java.lang.NullPointerException GoogleMaps V2

Question

Answer 1

Above mentioned problem can occur if you have emulator or device in which google play services are not installed. I don't have perfect solution but I figured out some work around to save your app from crashing. In this case you have to follow simple steps 1. Override startActivityForResult(intent, requestcode) 2. In startActivityForResult add super call super.startActivityForResult in try catch and catch the NullPointerException

Easy its done Now you can trap the nullpointerexception here and add your error handling in catch
