osmdroid映射不可见

Question

我在Android中使用osmdroid来满足我的映射需求。直到前几天，我可以看到地图，每一件事情是好的，但现在每天我的地图活动开始的时候，我得到一个空的地图和下面的跟踪：

这是怎么了我的onCreate代码如下像：

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); 

} 

和我的清单文件具有以下权限：

<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> 

有没有人遇到过这种，或者你有任何想法的问题是什么？
奇怪的是，它工作得很好，没有任何改变。

使用模拟器发生此问题。

解决方案：
所有我需要做的就是去到项目运行配置（右键单击项目 - >运行原样>运行配置），那么Android应用程序，然后进入“目标”选项卡及以下下“其他仿真器命令行选项”添加：

-dns-server 8.8.8.8

基本上，异常说它无法解析在线资源。

您确定您的设备连接到Wifi或3G吗？
