Remove "start"-activity from the history [duplicate]

Removing an activity from the history stack

I am looking for a solution to remove the StartActivity from the history stack. The StartActivity is the one that is being started at the beginning. I am using this Class to check some user values and want to redirect the user to the MainActivity if all is correct.

I have tried to set a flag:

addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);

but this does not do what it should.

App starts -> StartActivity -> MainActivity -> PRESS back -> the app should end

it does:

App starts -> StartActivity -> MainActivity -> PRESS back -> StartActivity

Thank for your help!

Edit: This is the code i am using to start the MainActivity:

Intent i = new Intent(context, DashBoardActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);

Answer 1

You should use FLAG_ACTIVITY_NO_HISTORY when starting StartActivity to achieve described behaviour.

The same you may achieve if you set noHistory attribute to true in your AndroidManifest.xml.

Answer 2

You can simply call finish() after you start the MainActivity.

Intent i = new Intent(context, DashBoardActivity.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
finish();
