报错信息主要是这些，已参考之前的提问，加上了mapView.refresh();
但是依然报错...
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//创建地图窗口
mapView = (MapView) this.findViewById(R.id.mapview);
//创建地图图层，利用iServer地图服务
LayerView layerView = new LayerView(this);
layerView.setURL(DEFAULT_URL);
//设置地图缩放
mapView.setBuiltInZoomControls(true);
//加载底图图层
mapView.addLayer(layerView);
mapView.refresh();
}
