I know this questions has already been asked hundreds of times, and it feels like I've been through them all without finding an answer.

I've been follwing an answer on how to add a marker to googlemaps.How to add overlay in google maps API v2 | Android |

I get no errors but when i run the app i get "program has stopped" and I get these errors in logcat:

Here's my main java:

package com.googlemaps;

import com.google.android.gms.maps.CameraUpdateFactory;
import com.google.android.gms.maps.GoogleMap;
import com.google.android.gms.maps.SupportMapFragment;
import com.google.android.gms.maps.model.BitmapDescriptorFactory;
import com.google.android.gms.maps.model.LatLng;
import com.google.android.gms.maps.model.MarkerOptions;

import android.os.Bundle;
import android.support.v4.app.FragmentActivity;
import android.view.Menu;

public class MapActivity extends FragmentActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
            setContentView(R.layout.activity_main); 
    LatLng sala = new LatLng(59.918434,16.618195);

    GoogleMap mMap;
    mMap = ((SupportMapFragment)(getSupportFragmentManager().findFragmentById(android.R.id.content))).getMap();
    mMap.setMapType(GoogleMap.MAP_TYPE_NORMAL);
    mMap.addMarker(new MarkerOptions()
            .position(sala)
            .title("Här ligger sala")
            .snippet("Detta är sala")
            .icon(BitmapDescriptorFactory.defaultMarker(BitmapDescriptorFactory.HUE_AZURE)));
    mMap.getUiSettings().setCompassEnabled(true);
    mMap.getUiSettings().setZoomControlsEnabled(true);
    mMap.animateCamera(CameraUpdateFactory.newLatLngZoom(sala,10));


}

And here's my xml:

    android:layout_width="match_parent"
    android:layout_height="match_parent"
    class="com.google.android.gms.maps.supportMapFragment"

    />
</RelativeLayout>

and also my manifest:

Oh thanks, didn't see that before posting the other answer. Still getting same error as before though.

Rajitha Siriwardena Over a year ago

your package is "com.googlemaps" but in your manifest you have typed com.go8oglemaps". That maybe the error causing your app to crash

setContentView(R.layout.your_xml_file);

add the above line after super.onCreate(savedInstanceState); in your onCreate() and update the result.

Sorry for taking such a long time to answer, my internet died on me. I updated logcat and java using your answer, and I seem to get some errors related to fragments. Any idea on the problem?

Gridtestmail Over a year ago

Make sure that you have added the Google Play Services Android library project to your application, where that class is defined. Also make sure that you are running your app on an API Level 11 or higher environment, since you are attempting to use native fragments (rather than the Android Support package's backport).

Gridtestmail Over a year ago

You are extending FragmentActivity, indicating that you are trying to use the Android Support package backport of fragments. However, your <fragment> element refers to MapFragment, which is for the native API Level 11 edition of fragments. Replace MapFragment with SupportMapFragment.

Erik Soderstrom Over a year ago

In can't see where i should replace MapFragment with SupportMapFragment, in my <fragment> I'm referring to the supportMapFragment class of the google_play_services_lib.

Gridtestmail Over a year ago

Ok that part is right. Have you added Google Play Service Android library project to your application?
