Android NullPointerException in Instrumentation.execStartActivity

android, instrumentation, nullpointerexception

Solution

I have the same error, I also use Google Maps API. It seems to happen on all Android versions and phones. Just to mention few:

AN10DG3, GT-I8190, F815, GT-I9300, GOOPHONE, HTC One, KFTT, MID8127, KFAPWI, AN10DG3

as I read somewhere, solution is:

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

- Override startActivityForResult(intent, requestcode)

- 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

@Override
public void startActivityForResult(Intent intent, int requestCode) {
    try {
        super.startActivityForResult(intent, requestCode);
    } catch (Exception e) {
        // fixes Google Maps bug: http://stackoverflow.com/a/20905954/2075875
    }
}
