I am implementing android application which is on web service. I'm creating login Activity A then homepage Activity B and so on.
Suppose there are A, B, C, D and E etc. activities. I'm creating a home button in Activity E and by clicking on that Activity E, D and C should finish and home Activity B should resume.
How can I implement that?
A > B > C > D > E > back button in E Activity > B.

Alright the best way to finish the current Activity is by using finish() method. So inside the onClick() of your button in the ActivityTwo you can do this. closeButton. setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { finish(); //closes ActivityTwo } });
exit(); or finish(); it exit full application or all activity.
Using an OnClickListenerInside your Activity instance's onCreate() method you need to first find your Button by it's id using findViewById() and then set an OnClickListener for your button and implement the onClick() method so that it starts your new Activity .
Take a look at the FLAG_ACTIVITY_CLEAR_TOP flag.
In essence it does the following. If the Activity this Intent is directed to is paused in your current back stack then it will resume it and clear the stack above it destroying all the activities in the stack above it.
UPDATE: In response to Jason Hanley.
Thanks for mentioning it. The documentation of FLAG_ACTIVITY_CLEAR_TOP covers that example. If you don't want Activity B to be recreated but just passed the new Intent then you should define its launch mode as singleTop.

Use onActivityResult method in chain . Start closing with the outermost activity-E when pressed on home , then check for its result and accordingly close activity-D and so on .
