Google Maps Api android key

I have some trouble testing my Android application which includes the google maps API. The ooficial API example worked just fine but if I copy the code into my own project it keeps saying: "The application has stopped unexpectedly". I looked up the key in the keystore several times and registered it with google. Even tried reinstalling the SDK. Does anybody know what the problem is?

Thanks in advance

Basically my code is:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    //connect to server

    //get current map scope

    //get media within map scope + a bit

    //init and show map
    setContentView(R.layout.main);
    //add zoom controls
    mapView = (MapView) findViewById(R.id.mapview);

    mapView.setBuiltInZoomControls(true); 


    //add menu
}

XML file line 6 would be:

<com.google.android.maps.MapView android:id="@+id/mapview" ...

followed by other lines of XML-parameters

First, do not answer your own question unless you are truly providing an answer. You can edit your question to add new materials, such as your longer stack trace.

Your exception is:

Caused by: java.lang.IllegalStateException: You are only allowed to have a single MapView in a MapActivity

This is because you are only allowed to have a single MapView in a MapActivity, and apparently you have two or more.

I know you are well past this issue, but I had the same issue, here are my notes about the same problem and how I was able to fix it.

You are only allowed to have a single MapView in a MapActivity

Delete a view and recreate it
