Android Studio - NullPointerException

[Titus Vasilescu]

Hey guys!I am getting a NullPointerException and I can't understand why.Here is my code:

    double SEATTLE_LAT = 7.359875;
    double SEATTLE_LNG = 60.403653;

if (servicesOK()) {
            setContentView(R.layout.activity_map);


            try {
                if (servicesOK()) {

                    gotoLocation(SEATTLE_LAT, SEATTLE_LNG);

                    Toast.makeText(this, "Ready to map!", Toast.LENGTH_SHORT).show();
                } else {
                    Toast.makeText(this, "gotoLocation not executed_1", Toast.LENGTH_SHORT).show();

                }
            }catch(Exception e){Toast.makeText(this, "gotoLocation not executed_2", Toast.LENGTH_SHORT).show();
                System.out.println("Exception is  : " + e);
            }
        } else {
            setContentView(R.layout.activity_main);
        }

 private void gotoLocation(double lat,double lng){
        LatLng latLng = new LatLng(lat, lng);
        CameraUpdate update = CameraUpdateFactory.newLatLng(latLng);
        mMap.moveCamera(update);

    }

Thanks in advance!Also I have a great idea for an application but having a very hard time writing it.If you would like to join me that would be great.

In which line does the exception occur? The full stack trace has that information. Also, which object is null? Have you checked that "mMap" is not null?

This is the Logcat:

There's just a single line? That's odd. Have you added additional logging to find out in which line the exception occurs, or stepped through it with a debugger?

Also:

Edited: I see, you're catching the exception, but do not print out the stacktrace. Change your catch handler to do that instead of discarding this vital information.

This is the stacktrace and I get a different error here and yes the Google mMap is null but even so it is working when I remove the gotoLocation method.

Okay, that's a searchable error.

Seems to be an error they have fixed. Have you updated recently? Also, check these links with provide some solutions:

OK, so you need to figure out why the code that's supposed to initialize it fails to do that. That happens in code you didn't post, so we can't help with that.
