    最近公司项目要实现一个定时向后台放送Gps数据,也就是经纬度,网上的Demo很多,基本都是没有封装过的,用起来很不方便,于是我自己动手封装了一个utilis工具,用起来很方便,直接调用,目前我只知道Android5.0以前的版本会出现异常,其他版本都支持

    public class LocationUtils {

    private static final long REFRESH_TIME =5000L;

    private static final float METER_POSITION =0.0f;

    private static ILocationListenermLocationListener;

    private static LocationListenerlistener =new MyLocationListener();

    private static class MyLocationListenerimplements LocationListener {

    @Override

            public void onLocationChanged(Location location) {//定位改变监听

                if (mLocationListener !=null) {

    mLocationListener.onSuccessLocation(location);

    }

    }

    @Override

            public void onStatusChanged(String provider,int status, Bundle extras) {//定位状态监听

            }

    @Override

            public void onProviderEnabled(String provider) {//定位状态可用监听

            }

    @Override

            public void onProviderDisabled(String provider) {//定位状态不可用监听

            }

    }

    /**

    * GPS获取定位方式

    */

        public static Location getGPSLocation(@NonNull Context context) {

    Location location =null;

    LocationManager manager =getLocationManager(context);

    //高版本的权限检查

            if (ActivityCompat.checkSelfPermission(context, Manifest.permission.ACCESS_FINE_LOCATION) != PackageManager.PERMISSION_GRANTED) {

    return null;

    }

    if (manager.isProviderEnabled(LocationManager.GPS_PROVIDER)) {//是否支持GPS定位

    //获取最后的GPS定位信息,如果是第一次打开,一般会拿不到定位信息,一般可以请求监听,在有效的时间范围可以获取定位信息

                location = manager.getLastKnownLocation(LocationManager.GPS_PROVIDER);

    }

    return location;

    }

    /**

    }

    String provider = manager.getBestProvider(criteria,true);

    if (TextUtils.isEmpty(provider)) {

    //如果找不到最适合的定位,使用network定位

                location =getNetWorkLocation(context);

    }else {
