clear Activity Stack when user Logs in

There are a lot of topics on this post. But i couldn't find a solution to my problem.

Let me describe my activity stack first.

SplashScreen->A->Login->Home.

What i would like to achieve is , when i click on back button after logging in to Home, i should come out of the application and go to Home if i use my application again. For this i am assuming i should clear the activity stack before Home, after i login. I would also like to preserve the activity stack if the user hasn't logged in yet.

I want this to work on or after 2.1

What i have tried already.

1. using finish() in Login Activity , before calling startActivity on Home. This will redirect me to A , if i use back button on Home.

2. All variations of FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_CLEAR_TOP . Nothing worked, when i use开发者_StackOverflow中文版 back button, i am redirected to login screen.

Any suggestions or simple solution to achieve this?

ok so use finish on all the activities that you want them to be popped before calling startActivity

go to Home if i use my application again

Simply save your login parameters in SharedPreference and from A startActivity Home directly if login successful.

You can also try to make use of BroadcastReceiver aswell if you want to try that route.

In your "SplashScreen" and "A" activities, in the onCreate method you can create and register and IntentFilter and a BroadcastReceiver like so:

Assuming you have a global variable called broadcastReceiver

IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction("ACTION_LOGIN");

                this.broadcastReceiver = new BroadcastReceiver() {

                    @Override
                    public void onReceive(Context context, Intent intent) {
                        finish();
                    }
                };

                registerReceiver(broadcastReceiver, intentFilter);

Also don't forget to unregister your receiver in the onDestroy method (this is to prevent memory leaks in the program):

    @Override
    protected void onDestroy() {
    unregisterReceiver(this.broadcastReceiver);
    super.onDestroy();
    }

Now in your "Login" activity, once the user has successfully logged in, you can broadcast a message to all the registered receivers, which will finish those activites in the back stack:

Intent broadcastIntent = new Intent();
broadcastIntent.setAction("ACTION_LOGIN");
sendBroadcast(broadcastIntent); 

Your SplashScreen and A activities will now be finished.
