是否可以使用推送通知使用运行同一应用程序的其他设备终止活动

Question

If it is possible to send a signal to kill an activity on a device using the same app from another device. Similar to a notification and when notification is clicked it opens an activity but in this case I would like to know if it is possible to close an activity without clicking the notification or something of the sort (Should all be done automatically as soon as the app, say receives a notification).

Answer 1

Send notification to the device you want to close it's activity and then use interface callback or eventbus to close the activity

here you can check if activity is active

 boolean active;

  @Override
  public void onStart() {
     super.onStart();
     active = true;
  } 

  @Override
  public void onStop() {
     super.onStop();
     active = false;
  }

Using eventbus

EventBus.getDefault().post(new MessageEvent());

 @Subscribe(threadMode = ThreadMode.MAIN)
  public void onMessageEvent(closeActivityEvent event) {

    if (active)
        this.finish();
    }

}

Using interface

activityInterface.closeActivity();

 @Override
   public void closeActivity() {
    if(active){
        this.finish();
    }

}
