我正在做一个与 Android Studio 中的地图有关的简单应用程序。当我用释放键运行它时，

 keytool -list -v -keystore C:\Users\Theodosios\maps.jks -alias mapsalias -storepass   
 larissa -keypass larissa

地图无法正确运行。如果我使用 debug.kestore 虽然一切正常。输出中的消息是

 01-06 00:17:00.904: E/ActivityThread(1665): 
 Service com.google.android.gms.backup.BackupTransportService has leaked    
 ServiceConnection com.google.android.gms.http.f@3c9e1e50 
 that was originally bound here.

我从 google 获取了 MainActivity 的代码。它非常简单。

public class MainActivity extends ActionBarActivity {
GoogleMap googleMap;
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    setContentView(R.layout.activity_main);

    createMapView();
    addMarker();
}

/**
 * Initialises the mapview
 */
private void createMapView(){
    /**
     * Catch the null pointer exception that
     * may be thrown when initialising the map
     */
    try {
        if(null == googleMap){
            googleMap = ((MapFragment) getFragmentManager().findFragmentById(
                    R.id.mapView)).getMap();

            /**
             * If the map is still null after attempted initialisation,
             * show an error to the user
             */
            if(null == googleMap) {
                Toast.makeText(getApplicationContext(),
                        "Error creating map", Toast.LENGTH_SHORT).show();
            }
        }
    } catch (NullPointerException exception){
        Log.e("mapApp", exception.toString());
    }
 }
 private void addMarker(){

    /** Make sure that the map has been initialised **/
    if(null != googleMap){
    Marker marker1=    googleMap.addMarker(new MarkerOptions()
                        .position(new LatLng(39.648141,22.413155))
                        .title("Marker")
                        .draggable(true)
        );
    }
  }
}

在清单文件中，我添加了必要的权限。
