Question

我终于设置了我的应用程序（跟踪实时GPS）以使用前台服务进行跟踪。但是，我现在遇到的问题是，即使我告诉了它，该服务也永远不会停止。每当我从位置客户端获取新位置时，我都会不断获取日志。我似乎在任何地方都找不到任何可以解释这一点的东西，因此将不胜感激。

服务的前几个相关方法如下所示……

@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com.google.android.gms.location.LocationRequest

mLocationClient是com.google.android.gms.common.api.GoogleApiClient

活动是这样启动的： ContextCompat.startForegroundService(this, buildLocationServiceIntent(true));

然后尝试停止它，如下所示： ContextCompat.startForegroundService(this, buildLocationServiceIntent(false)); 如果需要的话，此行位于活动的onDestroy方法中。

您看到的Log.i恰好出现在我的应用日志中。但是，我的onLocationChanged方法中的日志会在“停止”服务后无限期地发送。我确定我缺少简单的东西，只是看不到。

只要有绑定的组件，显式停止服务就不会终止该服务，并且解除所有组件的绑定过程直到显式停止（如果曾经启动过）都不会终止它。另外请注意，无论您调用了startService（）多少次，一次调用stopService（）或stopSelf（）都会停止它。我认为这个概念将帮助您解决问题。

编辑：由于信誉不高，我无法发表评论。因此，我正在编辑答案。

如果您确实允许启动和绑定服务，则在启动服务后，当所有客户端都解除绑定时，系统不会销毁该服务。相反，您必须通过调用stopSelf（）或stopService（）明确停止该服务。然后该服务将停止。
