Android 停止远程进程中的服务

在一个名为

MyApp:MyOtherProcess

的远程（特定于应用程序）进程中，我有一个名为

MyService

的后台服务当我刷走应用程序时，

MyApp:MyOtherProcess

和

MyService

会发生什么情况？

Apps=>Running Apps UI告诉我我有0个进程和1个服务。我将其解释为

MyApp:MyOtherProcess

未激活，但在

MyService

被唤醒时将被唤醒

我认为

MyService

仍在启动，然后尝试停止该服务

停止我的服务：

Intent i = new Intent(context, MyService.class);
if (isMyOtherProcessRunning(context)) {
  //Test case: I have swiped away the application
  //Ahh, nothing is logged so I think MyService.onDestory is not invoked!
  //Is MyService still running???
  context.stopService(context, i);
} else {
  //Test case: I have not swiped away the application
  //Good, "destroying" is logged so MyService.onDestroy was invoked!
  context.stopService(context, i);
}

public MyService : Service {
  @Override
  public void onCreate() {
    Log.d("MyService", "creating");
  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d("MyService", "starting");
    return START_REDELIVER_INTENT;
  }

  @Override
  public void onDestroy() {
    Log.d("MyService", "destroying");
  }
}

Intent i = new Intent(context, MyService.class);
if (isMyOtherProcessRunning(context)) {
  //Test case: I have swiped away the application
  //Ahh, nothing is logged so I think MyService.onDestory is not invoked!
  //Is MyService still running???
  i.putExtra("stopImmediately", true);
  context.stopService(context, i);
} else {
  //Test case: I have not swiped away the application
  //Good, "destroying" is logged so MyService.onDestroy was invoked!
  context.stopService(context, i);
}

public MyService : Service {
  @Override
  public void onCreate() {
    Log.d("MyService", "creating");
  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d("MyService", "starting");
    if (intent.getBooleanExtra("stopImmediately", false)) {
      this.stopSelf();
      return START_NOT_STICKY;
    }
    return START_REDELIVER_INTENT;
  }

  @Override
  public void onDestroy() {
    Log.d("MyService", "destroying");
  }
}

我的服务：

Intent i = new Intent(context, MyService.class);
if (isMyOtherProcessRunning(context)) {
  //Test case: I have swiped away the application
  //Ahh, nothing is logged so I think MyService.onDestory is not invoked!
  //Is MyService still running???
  context.stopService(context, i);
} else {
  //Test case: I have not swiped away the application
  //Good, "destroying" is logged so MyService.onDestroy was invoked!
  context.stopService(context, i);
}

public MyService : Service {
  @Override
  public void onCreate() {
    Log.d("MyService", "creating");
  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d("MyService", "starting");
    return START_REDELIVER_INTENT;
  }

  @Override

    Log.d("MyService", "destroying");
  }
}

  //Test case: I have swiped away the application
  //Ahh, nothing is logged so I think MyService.onDestory is not invoked!

  context.stopService(context, i);
}

public MyService : Service {
  @Override
  public void onCreate() {
    Log.d("MyService", "creating");
  }

  @Override
  public int onStartCommand(Intent intent, int flags, int startId) {
    Log.d("MyService", "starting");
    if (intent.getBooleanExtra("stopImmediately", false)) {
      this.stopSelf();
      return START_NOT_STICKY;
    }
    return START_REDELIVER_INTENT;
  }

  @Override
  public void onDestroy() {
    Log.d("MyService", "destroying");
  }
}

助手：

public boolean isMyOtherProcessRunning(Context applicationContext) {
  ActivityManager activityManager = (ActivityManager)applicationContext.getSystemService(Context.ACTIVITY_SERVICE);
  List<RunningAppProcessInfo> procInfos = activityManager.getRunningAppProcesses();
  for(int i = 0; i < procInfos.size(); i++)
  {
    String processName = procInfos.get(i).processName;
    if(processName.equals("MyApp:MyOtherProcess")) {
      return true;
    }
  }
  return false;
}

我的服务：

Intent i = new Intent(context, MyService.class);
if (isMyOtherProcessRunning(context)) {
  //Test case: I have swiped away the application
  //Ahh, nothing is logged so I think MyService.onDestory is not invoked!
  //Is MyService still running???
  context.stopService(context, i);
} else {
  //Test case: I have not swiped away the application
  //Good, "destroying" is logged so MyService.onDestroy was invoked!
  context.stopService(context, i);
}

public MyService : Service {
  @Override
  public void onCreate() {
    Log.d("MyService", "creating");
  }

  @Override

我正在三星Galaxy S5上运行Android 4.4.4 API 19，Genymotion版本为2.3.1。

我认为IntentService将帮助您解决这个问题。将您的服务扩展为IntentService，而不是希望自动停止的服务

IntentService是按需处理异步请求（表示为Intent）的服务的基类。客户端通过startService（Intent）调用发送请求；服务会根据需要启动，使用工作线程依次处理每个意图，并在其工作结束时自行停止。

我不明白：您调用stopService期望调用onStartCommand？不，我调用stopService并期望调用onDestroy。那么，为什么要在stopService的意图中额外传递“StopInstance”呢？你到底想实现什么？我不明白为什么stopService（）不调用onDestroy（）。为了解决这个问题，我尝试启动这个命令（它似乎唤醒了远程进程）。然后在我启动命令后立即停止它。我的变通方法在onStartCommand（）和onDestroy（）都被调用的地方可以正常工作。stopService返回什么？IntentService看起来非常有用！但是，既然我已经处于一个不同的过程中，那么这是必要的吗？但是您正在创建一个服务，不是吗？只需创建IntentService类型，即完成工作后要停止的服务。它就是为了这个目的而设计的。但我希望我的服务能够长期运行。
