这不是重复的，因为我的问题有点不同。
我尝试在应用程序关闭时每 20 分钟发送一次位置信息，但是当我使用时间间隔时，它不会很好地工作，所以我尝试使用 Handler 来获取数据每 20 分钟一类。另外，代码引用是基于另一个我不记得的问题的答案，我只是更改了一些部分。
此构建基于一些答案，这是我在做作业时尝试的，当我尝试使用 minTimeInterver 应用程序时以某种方式忽略位置更改，这就是我使用处理程序的原因。所以整个想法是每 20 分钟发送一次位置信息。
这是 Activity 设置:
mYourService = new MyService();
mServiceIntent = new Intent(this, mYourService.getClass());
if (!isMyServiceRunning(mYourService.getClass())) {
startService(mServiceIntent);
}

实现JobService是最好的选择，您可以根据自己的需求进行修改。更多信息请参见官方site
