android - 在Android中，proxy_gps_nmea_cb()有什么用？

Question

我打电话

locationManager.requestSingleUpdate(locationManager.GPS_PROVIDER, locationListener, Looper.myLooper());

在一个线程中

scheduleTaskExecutor.scheduleAtFixedRate();

我显示的 logcat 消息如下:

这是否意味着 gps 当前正在积极工作，消耗电池？

Answer 1

据我了解，GPS 确实在运行并耗电。我暂时没能找到解决方案，但如果我找到了，我会告诉你(如果你自己找到了，请回答你的问题，它可以节省我一些时间!)
