How to "destroy" multiple Android activities at same time

Question

I have sort of wizard in app going through 6 Activities.

so I call:

Main Activity - Call Option 1 - Call Option 2 - Call Option 3 - Call Option 4 - Call Option 5

Now, on Option 5 I perform save of the whole action to database, and at that point I need to go back to Main Activity and destroy Option1,2,3,4 and 5.

Until Option 5 saves to database, I need to be able to go back, do changes, go forth to Option 5 and save it.

IS proper way to do it that I somehow create method that would have:

private void cleanStack(){
   Option1.finish();
   Option2.finish();
   Option3.finish();
   Option4.finish();
   Option5.finish();
}

And then start (or resume) Main Activity?

Tnx

Use the following to clear the stack :

Intent intent = new Intent ( this , MainActivity.class );
intent.addFlags ( Intent.FLAG_ACTIVITY_CLEAR_TOP );
startActivity ( intent );

In this manner, since in the stack you have : Main Activity -> Call Option 1 -> Call Option 2 -> Call Option 3 -> Call Option 4 -> Call Option 5

If you start the MainActivity using the clear top flag, all activities in the stack on top of the MainActivity will be finished.
