Android8.0适配前台定位服务service的示例代码

Intent serviceIntent = new Intent(this, ForegroundLocationService.class);
bindService(serviceIntent, conn, Service.BIND_AUTO_CREATE);
// 绑定服务时要求传入一个ServiceConnection实现类的对象
// 绑定服务时，会触发服务的onBind方法，此方法会返回一个Ibinder的对象给activity / fragment的onServiceConnected()，通过这个对象可以访问服务中的方法
  ServiceConnection conn = new ServiceConnection() {
    @Override
    public void onServiceDisconnected(ComponentName name) {
    }
    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
    }
  };

  public class MyBinder extends Binder {
    public ForegroundLocationService getService(){
      return ForegroundLocationService.this;
    }
  }
  //通过binder实现调用者client与Service之间的通信
  private MyBinder binder = new MyBinder();
  //通过service的onBind()方法返回我们实例化的MyBinder对象，该对象可以获的当前的Service
  @Override
  public IBinder onBind(Intent arg0) {
    NotificationUtils notificationUtils = new NotificationUtils(this);
    startForeground(111, notificationUtils.getNotification("Notice", "Continuous positioning",null));
    return binder;
  }

  ServiceConnection conn = new ServiceConnection() {

    @Override
    public void onServiceDisconnected(ComponentName name) {
    }
    @Override
    public void onServiceConnected(ComponentName name, IBinder service) {
        //通过这个方法可以得到service的实例，通过设置回调可以持续更新
        ForegroundLocationService foregroundLocationService = ((ForegroundLocationService.MyBinder) service).getService(); 
        foregroundLocationService.setLocationCallback(new ForegroundLocationService.LocationCallback() {
          @Override
          public void onLocation(Location location) {

        }
      })；
    }
  };

  public interface LocationCallback {
    /**
    * 当前位置
    */
    void onLocation(Location location);
  }
  private LocationCallback mLocationCallback;
  private class LocationListener implements android.location.LocationListener {
    public LocationListener(String provider) {
      Logger.e(TAG, "LocationListener " + provider);
    }
    @Override
    public void onLocationChanged(Location location) {
      Log.i("location", "onLocationChanged: " + "当前坐标：" + location.getLatitude() + " : " + location.getLongitude());
      if(mLocationCallback!=null){
        mLocationCallback.onLocation(location);
      }
    }
