2.0 LocationService定位服务(定位信息的基本配置)

mOption.setCoorType("bd09ll");//可选,默认gcj02,设置返回的定位结果座标系,如果配合百度地图使用,建议设置为bd09ll;
mOption.setScanSpan(3000);//可选,默认0,即仅定位一次,设置发起连续定位请求的间隔需要大于等于1000ms才是有效的

3.0 在Application中进行对SDK进行初始化
public class LocationApplication extends Application {
public LocationService locationService;
public Vibrator mVibrator;
@Override
public void onCreate() {
super.onCreate();
/***
* 初始化定位sdk,建议在Application中创建
*/
locationService = new LocationService(getApplicationContext());
mVibrator =(Vibrator)getApplicationContext().getSystemService(Service.VIBRATOR_SERVICE);
SDKInitializer.initialize(getApplicationContext());
}
}
