告诉我，为什么不起作用？给予每一秒。并显示一个空白单元格。

在此处输入图像描述

设置“AndroidManifest”应该没问题，因为工作前几个小时。

ActivityThread Failed to find provider info for com.google.android.gsf.gservices

几个小时前，一切正常，没有任何改变。

public class TravelMapActivity extends FragmentActivity {

    private GPSTrackerService gpsService;

    private SupportMapFragment mMapFragment;
    private GoogleMap googleMap;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.travel_map_activity);

        SupportMapFragment supportMapFragment = (SupportMapFragment)
                getSupportFragmentManager().findFragmentById(R.id.map);
                googleMap = supportMapFragment.getMap();

//This option does not work either.

//      mMapFragment = new SupportMapFragment();
//      try {
//          MapsInitializer.initialize(this);
//      } catch (GooglePlayServicesNotAvailableException e) {
//          // TODO handle error
//          e.printStackTrace();
//      }
//      getSupportFragmentManager().beginTransaction().add(android.R.id.content, mMapFragment).commit();

    }
