我终于设置好了我的应用程序(跟踪实时GPS)以使用前台服务进行跟踪。然而,我现在遇到的问题是,即使我告诉它停止,服务也永远不会停止。每当我从位置客户端获取新位置时,我都会收到日志。我似乎找不到任何解释这个问题的东西,所以希望能得到帮助。
服务的前几个相关方法如下...
@Override
public void onCreate() {
NotificationManager notificationManager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
String channelId = Build.VERSION.SDK_INT >= Build.VERSION_CODES.O ? createNotificationChannel(notificationManager) : "";
NotificationCompat.Builder notificationBuilder = new NotificationCompat.Builder(this, channelId);
Notification notification = notificationBuilder.setOngoing(true)
.setSmallIcon(R.mipmap.ic_launcher)
.setPriority(PRIORITY_MIN)
.setCategory(NotificationCompat.CATEGORY_SERVICE)
.build();
startForeground(ID_SERVICE, notification);
}
@RequiresApi(Build.VERSION_CODES.O)
private String createNotificationChannel(NotificationManager notificationManager){
String channelId = "my_service_channelid";
String channelName = "My Foreground Service";
NotificationChannel channel = new NotificationChannel(channelId, channelName, NotificationManager.IMPORTANCE_HIGH);
// omitted the LED color
channel.setImportance(NotificationManager.IMPORTANCE_NONE);
channel.setLockscreenVisibility(Notification.VISIBILITY_PRIVATE);
notificationManager.createNotificationChannel(channel);
return channelId;
}
@Override
public int onStartCommand(Intent intent, int flags, int startId) {
super.onStartCommand(intent, flags, startId);
if (intent.getAction().equals(Constants.STARTFOREGROUND_ACTION)) {
Log.i(TAG, "Received Start Foreground Intent");
mLocationClient = new GoogleApiClient.Builder(this)
.addConnectionCallbacks(this)
.addOnConnectionFailedListener(this)
.addApi(LocationServices.API)
.build();
mLocationRequest.setInterval(LOCATION_INTERVAL);
mLocationRequest.setFastestInterval(FASTEST_LOCATION_INTERVAL);
mLocationRequest.setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY);
mLocationClient.connect();
} else if (intent.getAction().equals(Constants.STOPFOREGROUND_ACTION)) {
Log.i(TAG, "Received Stop Foreground Intent");
mLocationClient.disconnect();
mLocationClient.unregisterConnectionCallbacks(this);
stopForeground(true);
stopSelf();
}
//Make it stick to the notification panel so it is less prone to get cancelled by the Operating System.
return START_STICKY;
}
mLocationRequest
是一个 com.google.android.gms.location.LocationRequest
mLocationClient
是一个 com.google.android.gms.common.api.GoogleApiClient
Activity 这样启动它:ContextCompat.startForegroundService(this, buildLocationServiceIntent(true));
并尝试这样停止它:ContextCompat.startForegroundService(this, buildLocationServiceIntent(false));
这行代码在 activity 的 onDestroy
方法中,如果有影响的话。
你看到的 Log.i
出现在 app 日志中的时间与预期相同。但是在 '停止' 服务后,我的 onLocationChanged
方法中的日志仍然一直出现。我确定我错过了一些简单的东西,只是没有看到它。

Context.stopService()
,并在服务的onDestroy()
中处理所有销毁等操作呢? - TheWandererContext.stopService()
,但是在活动中我可以访问到stopService(Intent)
。这是你的意思吗?如果是的话,我已经尝试过了,但为了确保,我会再试一次。 - NieminenstopSelf()
行设置调试断点吗?检查一下应用是否到达了那一行。 - Aaditya Brahmbhatt
