除非位置发生变化，否则FusedLocation服务不会定期更新？

Question

我已编写服务以在我的应用中提供位置更新。问题是位置服务不提供位置更新，除非位置已更改。我正在使用模拟器来测试它。以下是代码：

 mGoogleApiClient = new GoogleApiClient.Builder(this)
                .addConnectionCallbacks(this)
                .addOnConnectionFailedListener(this)
                .addApi(LocationServices.API)
                .build();

     mLocationRequest = new LocationRequest();
     mLocationRequest.setInterval(UPDATE_INTERVAL_IN_MILLISECONDS);
     mLocationRequest.setFastestInterval(FASTEST_UPDATE_INTERVAL_IN_MILLISECONDS);
     mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);

基于this回答。 setInterval方法应该定期更新。

这里有什么问题？
