百度地图SDK 踩坑之旅------百度定位OnReceiveLocation没回调，什么都没有。

百度地图定位SDK在各位开发者手里捣弄的机会应该蛮多的。但是我们的百度SDK用起来并没有想像中的顺手，下面这个坑我估计很多同胞遇到过。按照BAIDU提供的Demo定位是没有问题的，但是我移植过来为什么OnReceiveLocation没有回调呢？我已经注册监听了，权限也配置了，服务也添加了，怎么没有反应呢？先别急，往下看：

• Application

  @Override    public void onCreate() {        super.onCreate();        if(appcontext == null){            appcontext = getApplicationContext();        }        //初始化定位服务        locationService = new LocationService(appcontext);       SDKInitializer.initialize(getApplicationContext());    }

• JNILib
  

• jar包
  

• AndroidManifest.xml配置

• Service服务

• 开启定位服务在需要触发的位置调用

    private void queryPostion() {        //开启定位服务        // -----------location config ------------        myapplication = (MyApplication) getActivity().getApplication();        locationService = myapplication.locationService;        //获取locationservice实例，建议应用中只初始化1个location实例，然后使用，可以参考其他示例的activity，都是通过此种方式获取locationservice实例的        locationService.registerListener(mListener);        //注册监听        int type = getActivity().getIntent().getIntExtra("from", 0);        if (type == 0) {            locationService.setLocationOption(locationService.getDefaultLocationClientOption());        } else if (type == 1) {            locationService.setLocationOption(locationService.getOption());        }        //开始定位服务        locationService.start();    }

• 结果回调

    /*****     * 定位结果回调，重写onReceiveLocation方法     */    private BDLocationListener mListener = new BDLocationListener() {        @Override        public void onReceiveLocation(BDLocation location) {            Log.d("hlhlocation", "onReceiveLocation: location"+location);            if (null != location && location.getLocType() != BDLocation.TypeServerError) {                if (user != null) {                    StringBuffer sb = new StringBuffer(256);                    sb.append("time : ");                    /**                     * 时间也可以使用systemClock.elapsedRealtime()方法 获取的是自从开机以来，每次回调的时间；                     * location.getTime() 是指服务端出本次结果的时间，如果位置不发生变化，则时间不变                     */                    sb.append(location.getTime());

• 坑（OnReceiveLocation没有回调）去看看你的 AndroidManifest.xml配置。
