后台服务不会停止 Android
[英]Background Service not Stopping Android
问题描述
I have background services which captures location from the users device but when I stop it using the stopService method from anther activity it does not stop and due to this the app crashes as the app is not able to send the lat long to server.
我有后台服务，可以从用户设备捕获位置，但是当我使用来自花药活动的 stopService 方法停止它时，它不会停止，因此应用程序崩溃，因为应用程序无法将经纬度发送到服务器。
Note - I have a retrofit post request which is made to the server when the location is not null and also when I click on the stop service button in main activity the notification disappears from the device but actually the service does not stop and the location is logged in the logcat.注意 - 我有一个改造后的请求，当位置不为空时，当我点击主活动中的停止服务按钮时，通知从设备中消失，但实际上服务并没有停止，位置是登录 logcat。 But it is not posted to the server due to this timeout error is received and app crashes.但由于收到此超时错误并且应用程序崩溃，它不会发布到服务器。

Start service like below:启动服务如下：
Intent intent = new Intent(this, LiveLocationService.class);
intent.putExtra("empCode", empCode);
intent.putExtra("year", year);
intent.putExtra("month", month);
intent.putExtra("date", dateToday);
startService(intent);
ContextCompat.startForegroundService(this, intent)
Stop service like below:停止服务如下：
stopService(new Intent(this, LiveLocationService.class));
Service onDestory() method like below:服务 onDestory() 方法如下：
@Override
public void onDestroy() {
super.onDestroy();
// Stop location udates
//hide your notification here
}

your service stops working but still getting location callbacks, means you still have registered callback in client.requestLocationUpdates() .您的服务停止工作但仍然收到位置回调，这意味着您仍然在client.requestLocationUpdates()注册了回调。
while stopping the service also remove the same callback from LocationProvderClient.在停止服务的同时，也从 LocationProvderClient 中删除相同的回调。 For that make global object of LocationCallback() remove that same object when need to stop.为此，在需要停止时，让 LocationCallback() 的全局对象删除相同的对象。 as:作为：
LocationServices.getFusedLocationProviderClient(this).removeLocationUpdates(locationCallback);
