Is root activity the current first activity in the stack or the activity specified as launch activity in manifest?
<p>Is root activity the current first activity in the stack or the activity specified as launch activity in manifest?</p>

<p>Support application P starts activity A at launch. Then A starts B and finish itself, and then B starts C. Now the stack contains B and C, with B the first in the stack.</p>

<p>Can I say B is the root activity, or A is still the root activity.</p>

<p>I want to make clear of it because I am trying to understanding the definition of clearTaskOnLaunch:</p>

<p>android:clearTaskOnLaunch
    Whether or not all activities will be removed from the task, except for the root activity,   whenever it is re-launched from the home screen — "true" if the task is always stripped down to its root activity, and "false" if not.</p>
