肉眼看不见的机器人地图
肉眼看不见的机器人地图
提问于 2011-08-22 08:13:12
我在Android中使用osmdroid来满足映射需求。直到几天前，我还能看到地图，一切都还好，但现在每当我的地图活动开始时，我就会得到一张空地图和下面的跟踪：

//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);
}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.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情况，或者你知道问题出在哪里？
奇怪的是，它运转得很好，什么也没有改变。
此问题正在使用仿真器发生。
解决方案：
我所要做的就是转到项目运行配置(右键单击project->run >right)，然后转到android应用程序，然后转到"target“选项卡和下面的”附加仿真命令行选项“下：

基本上，例外说它不能解决在线资源。
您确定您的设备已连接到Wifi或3G吗？
