getMap（）函數中的錯誤

我只是創建一個Map項目並執行此代碼。但有getMap（）錯誤。我嘗試了一些來自互聯網的示例代碼，但getMap（）函數中也存在相同的錯誤。代碼是：getMap（）函數中的錯誤

private GoogleMap mMap; 
    static final LatLng TutorialsPoint = new LatLng(21 , 57); 
    @Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_maps); 


    if (mMap == null) { 
     SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() 
       .findFragmentById(R.id.map); 
     mapFragment.getMapAsync(this); 

    try { 
     if (mMap == null) { 

        mMap = ((MapFragment) getFragmentManager(). 
        findFragmentById(R.id.map)).getMap(); 
        //findFragmentById(R.id.map)).getMap(); 
     } 
     mMap.setMapType(GoogleMap.MAP_TYPE_HYBRID); 
     Marker TP = mMap.addMarker(new MarkerOptions(). 
       position(TutorialsPoint).title("TutorialsPoint")); 
    } 
    catch (Exception e) { 
     e.printStackTrace(); 
    } 
} 




@Override 
public void onMapReady(GoogleMap googleMap) { 
    mMap = googleMap; 

    // Add a marker in Sydney and move the camera 
    LatLng sydney = new LatLng(-34, 151); 
    mMap.addMarker(new MarkerOptions().position(sydney).title("Marker in Sydney")); 
    mMap.moveCamera(CameraUpdateFactory.newLatLng(sydney)); 
}

你會得到什麼錯誤？理想情況下，包括整個堆棧應該有所幫助 – Acapulco

@Acapulco Error Mesg顯示爲： - 12:59:34 AM IllegalStateException：由於ConnectorServiceRegistry已關閉，無法找到DefaultGradleConnector類型的對象的工廠。 1:01:55 AM IllegalStateException：由於ConnectorServiceRegistry已關閉，無法找到DefaultGradleConnector類型的對象的工廠。上午1:02:47 IllegalStateException：無法找到DefaultGradleConnector類型的對象的工廠，因爲ConnectorServiceRegistry已關閉。 – RedEyes

@Acapulco你能幫我嗎？ – RedEyes

你應該添加標記到地圖時onMapReady功能被觸發，當你的地圖就可以使用（如添加標記等）。只是初始化您的地圖，並呼籲getMapAsync功能像

這種情況發生

SupportMapFragment mapFragment = (SupportMapFragment) getSupportFragmentManager() 
      .findFragmentById(R.id.map); 
    mapFragment.getMapAsync(this);

使用googleMap對象來操縱你在onMapReady內給你的地圖。
