.xml呢？有没有增加权限

xml文件是否加了如下服务申明
android:name="com.baidu.location.f"
android:enabled="true"
android:process=":remote" >

是不是会崩溃啊？是不是location为null的原因啊？我把下面的代码放到onReceiveLocation（BDLocation location）里面就好啦
// 构造定位数据
MyLocationData locData = new MyLocationData.Builder()
.accuracy(location.getRadius())
// 此处设置开发者获取到的方向信息，顺时针0-360
.direction(100).latitude(location.getLatitude())
.longitude(location.getLongitude()).build();
// 设置定位数据
mBaiduMap.setMyLocationData(locData);
// 设置定位图层的配置（定位模式，是否允许方向信息，用户自定义定位图标）
BitmapDescriptor mCurrentMarker = BitmapDescriptorFactory
.fromResource(R.drawable.icon_st);
MyLocationConfiguration config = new MyLocationConfiguration(null,
true, mCurrentMarker);
mBaiduMap.setMyLocationConfigeration(config);

    还有下面这句，我放在了onDestroy()里
    // 当不需要定位图层时关闭定位图层
mBaiduMap.setMyLocationEnabled(false);

请问你解决了么？我现在也是这个问题

LocationClient(getApplicationContext()); 这句话错了，应该是LocationClient(this);
