How to dismiss previous activities in android at a certain point?
<p>I have activities A -> B -> C where A and B are for login and verification purpose. When a user reaches activity C, A and B are not necessary any more. That means if a user press BACK in C, the application should not go thru A and B, instead it should go back to HOME screen.</p>

<p>What's the conventional way to implement this in android? Thanks.</p>

<p>EDIT: to clarify a bit, user should be able to go back to A from B during login/verification phase, but not from C to A or B once the user reaches C.</p>
