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);
}
}
