You can set android:noHistory="true"
for all your activities at AndroidManifest.xml. Hence they will not place themselves onto history stack and back button will bring you to the home screen.
How to kill all my activities in android?
Thank you for all who respond for my question. Finally i got the solution for my issue. I resolved that by using the intent Intent.FLAG_ACTIVITY_CLEAR_TOP. Here is explanation for my scenario.
Assume i am in Activity D. My actual flow is A->B->C->D.i want to kill my previous activities A,B,C. I used to call my first activity A when i am going from Activity D.
So i added intent FLAG_ACTIVITY_CLEAR_TOP to call activity A. So the middle activities will cleared and will show only Activity A. And i am passing some flag value as intent extras to activity A. like this
Intent intent = new Intent(D.this,A.class);
intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
intent.putExtra("finishstatus", true);
this.startActivity(intent);
this.finish();
and i am checking the bundle value in onCreate method of Activity A like
bundle = this.getIntent().getExtras();
if(bundle!= null)
{
boolean isActivityToBeFinish = this.getIntent().getExtras().getBoolean("finishstatus");
if(isActivityToBeFinish)
{
finish();
}
}
If the status value available and it is true then i am finishing the activity A also. So my problem is cleared and i am successfully finishing the all previous activities.
May be my explanation is not good but will work perfectly.

It might also be worth taking a look into the different launch modes for activities. For example, you could use the singleInstance
on your 'root' activity to always return to that the same instance - meaning Android will not push another Activity instance on the back stack when you call startActivity(...)
, but pop everything inbetween and deliver the intent to the already existing instance. Alternatively, singleTask
will give you similar, yet slightly different behaviour.
Have a read through the Task and Back Stack article on Android's developer website. It gives a nice overview of and explains the different launch modes.
