当用户完全退出（销毁）应用程序时，是否可以实现会话注销？

Question

已创建会话注销功能，在以下情况下会发生非活动注销： 1.) 有一段时间不活动 2.) 应用被推送到后台，当用户恢复应用/活动时，活动仍然会执行超时注销 3.) 屏幕超时，进入屏保模式

但是，我想知道当用户在退出/将应用程序推入后台后完全终止应用程序时，是否可能发生非活动注销。如果可能，有哪些可能的实现方式？

这里是sn-p的代码：

（在非活动期间调用的功能）：

@Override
public void onStop(){
     super.onStop();
     //Timer needs to be stopped when user manually pressed BACK button
     //Prevent a logout when user press BACK button to stop each activity destroyed from being logged
     startTime = System.currentTimeMillis();
     Log.i("RootActivity:onResume()","******startTime=******"+startTime);
     stopDisconnectTimer();
}

//METHOD USED FOR INACTIVITY LOGOUT
//EMPLOY THE HANDLER METHOD FOR OCCURANCE OF FUTURE FUNCTION: DISCONNECTHANDLER
public static class MyBaseActivity extends Activity {

    public static Handler disconnectHandler = new Handler(){
        public void handleMessage(Message msg){ 
        }
    };

}

private Runnable disconnectCallback= new Runnable(){
    @Override
    public void run(){
        //Get the Resume Time & get difference in Time for Logout
        long endTime= System.currentTimeMillis();
        Log.i("RootActivity:onResume()","******endTime=******"+endTime);
        long diff = endTime - startTime;
        long secInt = (diff /1000); //conversion of milliseconds into seconds
        Log.i("RootActivity:onRun()","******sectInt=******"+secInt);
        if (secInt > Inactivity_Timeout){// SET EXIT SCREEN INTERVAL LOGOUT
        IdleLogout();
        }   
    }
};

//METHOD TO CALL ON RESETDISCONNECT WHEN USER ACTIVITY RESUMES
public void resetDisconnectTimer(){
    MyBaseActivity.disconnectHandler.removeCallbacks(disconnectCallback);
    MyBaseActivity.disconnectHandler.postDelayed(disconnectCallback, Inactivity_Timeout);
}

//METHOD TO CALL ON STOPDISCONNECT WHEN USER PRESS BACK BUTTON
public void stopDisconnectTimer(){
    MyBaseActivity.disconnectHandler.removeCallbacks(disconnectCallback);
}

Answer 1

将您的注销代码放入 onDestroy 方法中。当用户销毁应用程序时将调用此方法 -

@Override
protected void onDestroy() {
    super.onDestroy();
    //Log out the user
}

Answer 2

获取单独的类并扩展应用程序 如下

//*************************************************** ************************

   public class AppController extends Application{


  public static final String TAG1 = "SCREEN";
  ConnectionDetector cd;
  Boolean isInternetPresent = false;     
  private BroadcastReceiver scrOnReceiver;
    private BroadcastReceiver scrOffReceiver;
    private IntentFilter scrOnFilter;
    private IntentFilter scrOffFilter;
public static final String TAG = AppController.class.getSimpleName();

private RequestQueue mRequestQueue;

private static AppController mInstance;

@Override
public void onCreate() {
    super.onCreate();

 // creating connection detector class instance
    cd = new ConnectionDetector(getApplicationContext());
    // get Internet status
    isInternetPresent = cd.isConnectingToInternet();

    new BroadcastReceiver(){

        @Override
        public void onReceive(Context context, Intent intent) {
              if (isInternetPresent) {
                  Toast.makeText(getApplicationContext(), "internet connection", Toast.LENGTH_SHORT).show();
                }
                else{
                    Toast.makeText(getApplicationContext(), "Please check the internet connection", Toast.LENGTH_SHORT).show();
                    Intent intent1=new Intent(AppController.this,LoginActivity.class);
                    intent1.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);

                    Log.d("***********", "logout");
                }
        }

    };





    //Fabric.with(this, new Crashlytics());
    mInstance = this;

    scrOnReceiver = new BroadcastReceiver() { 
        @Override 
        public void onReceive(Context context, Intent intent) { 
            Log.d(TAG1, "SCREEN ON"); 
            timer.cancel();
        } 
    };

    scrOnFilter = new IntentFilter(Intent.ACTION_SCREEN_ON); 

    scrOffReceiver = new BroadcastReceiver() {
        @Override

            timer.start();



        }
    };

    scrOffFilter = new IntentFilter(Intent.ACTION_SCREEN_OFF);

    registerReceiver(scrOnReceiver, scrOnFilter);
    registerReceiver(scrOffReceiver, scrOffFilter);
}

public static synchronized AppController getInstance() {

    return mRequestQueue;

    getRequestQueue().add(req);

}



CountDownTimer timer = new CountDownTimer(1*60*1000, 1000) {

    public void onTick(long millisUntilFinished) {

        Log.d("timer", "****"+millisUntilFinished);

    }

    public void onFinish() {
       //Logout

            e.printStackTrace();

    }

@Override
