Question

我正在使用omdroid 3.0.8测试一个非常简单的OSM应用程序（并在实际的HTC Desire设备上进行测试）。多数民众赞成我想做的事情：

final org.osmdroid.views.MapView mapView = new org.osmdroid.views.MapView(this, 256);                          
setContentView(mapView);                          
mMapView = mapView;                            
final org.osmdroid.views.overlay.MyLocationOverlay mlo = new org.osmdroid.views.overlay.MyLocationOverlay(this, mapView);                          
mapView.getOverlays().add(mlo);                          
mMyLocationOverlay = mlo;
mMapView.getController().setZoom(14);                  
mMapView.getController().setCenter(new GeoPoint(52370816, 9735936));                 
mMyLocationOverlay.disableMyLocation();

尝试获取OSM MapView我只获得一个网格，并在LogCat中“IO Exception下载MapTile”：

......等等。设备上的网络连接是可以的，而且，使用相同地图的OsmAnd应用没有任何问题。我需要在线获取地图，这就是重点。如何从我的应用程序中获取OSM地图？

我解决了这个问题。它与sdcard上的权限 - OSM下载磁贴相关联，因此需要WRITE_EXTERNAL_STORAGE权限。
