Finish an activity in android?

I have some sets of activity.

Home Activity -> Activity 1 -> Activity 2 -> Activity 3 -> HomeActivity
                 finish();      finish();     finish();

Home Activity -> Activity 1 -> Activity 2 -> Activity 3 -> Activity 4 -> HomeActivity
                 finish();      finish();     finish();     finish();

So now when I am on the final step that is on the HomeActivity if I press back button it again takes me on to the home activity.

How do I finish the home activity without disturbing the whole process? Any help appreciated.

Intent i = new Intent(Activity3.this,HomeActivity.class);
startActivity(i);
HomeActivity.this.finish();

while calling Activity 3 -> HomeActivity finish()

implement below code :

Intent i = new Intent(Activity3.this,HomeActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();

use this flag with your intent in each activity

i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

This will not launch home activity again . It will use the previous instance of you Home Activity and bring it to top.

with CLEAR_TOP If the activity being launched is already running in the current task, then instead of launching a new instance of that activity, all of the other activities on top of it will be closed and this Intent will be delivered to the (now on top) old activity as a new Intent.

You can refer this Link to get more idea about flags.

Allright whenever u call your HomeActivity just add this to your Intent

Intent i=new Intent(yourActivity.this,HomeActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();

This will clear any previous present activities stack. Hope it helps.

Whenever you switch from one activity to another by defalut onPause() will be called, if you dont want this activity(in your case home activity), just override onPause() in your home activity and call finish() in onPause().

call finish on the first home activity as well. i.e when you start activity 'Activity 1' after startactivity() call finish also.
