百度地图定位空指针问题解决

在Activity中引入百度地图，第一次显示没问题，第二次回调onReceiveLocation(BDLocation bdLocation)  以下这句代码baiduMap.setMyLocationConfigeration(config);报空指针异常。错误日志如下：

解决办法，在OnDestroy中增加代码mLocationClient.stop();即可，修改代码如下：

@Override

public voidonDestroy() {

       super.onDestroy();

      if(routePlanSearch!=null) {

               routePlanSearch.destroy();

    }

          mLocationClient.stop();

      if(mapView!=null) {

             mapView.onDestroy();

     }

      if(handler!=null){

           handler.removeCallbacksAndMessages(null);

     }

}
