osmdroid映射不可見

Question

我在Android中使用osmdroid來滿足我的映射需求。直到前幾天，我可以看到地圖，每一件事情是好的，但現在每天我的地圖活動開始的時候，我得到一個空的地圖和下面的跟蹤：

這是怎麼了我的onCreate代碼如下像：

super.onCreate(savedInstanceState); 
    this.me = this; 
    this.mMapView = new MapView(this, 256); 
    //this.mMapView = (MapView) findViewById(R.id.map); 

    this.mMapView.setTileSource(TileSourceFactory.MAPNIK); 
    this.mMapView.setClickable(true); 
    this.mMapView.setBuiltInZoomControls(true); 

    this.mMapView.getController().setZoom(10); 
    this.mMapView.getController().setCenter(new GeoPoint(39.461078, 2.856445)); 

    //register BrodCastListener! - remember to unregister! 
    IntentFilter filter = new IntentFilter(); 
    filter.addAction(UpdateRequester.ACTION); 
    this.registerReceiver(this.mUpdateReciever, filter); 

    //make map seen 
    setContentView(this.mMapView); 

} 

和我的清單文件具有以下權限：

<uses-permission android:name="android.permission.ACCESS_WIFI_STATE" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /> 
<uses-permission android:name="android.permission.INTERNET" /> 

<uses-feature android:name="android.hardware.location.network" /> 
<uses-feature android:name="android.hardware.location.gps" 
      android:required="true"/> 
<uses-feature android:name="android.hardware.wifi" /> 
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission> 
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission> 
<uses-permission android:name="android.permission.ACCESS_MOCK_LOCATION"></uses-permission> 
<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission> 

有沒有人遇到過這種，或者你有任何想法的問題是什麼？
奇怪的是，它工作得很好，沒有任何改變。

使用模擬器發生此問題。

解決方案：
所有我需要做的就是去到項目運行配置（右鍵單擊項目 - >運行原樣>運行配置），那麼Android應用程序，然後進入「目標」選項卡及以下下「其他仿真器命令行選項」添加：

-dns-server 8.8.8.8

基本上，異常說它無法解析在線資源。

您確定您的設備連接到Wifi或3G嗎？
