Finishing (or Accessing) a specific Activity in Android -

as activities opened user, they're stacked on view stack. , user finishes activity means, popped out of view stack.

now, have situation user has opened app's home screen, , has successively opened multiple activities, on top of home screen. in each activity, there's control lets user see home screen again.

as can think, there can 2 approaches this:

1. on press of control, pop home screen bottom of view stack , push on top of it.
2. as control pressed, start popping each of current screen until home screen becomes current screen.

i know there's way in android @ least 1 of this, or this. can't remember it.

please me choose better approach, , let me know way (the code, specifically) it.

thanks lot :)

(please edit title/text if isn't appropriate)

try this

intent = new intent();     i.putextra(extra_key_artist, id);     i.setclass(this, artistactivity.class);     i.addflags(intent.flag_activity_single_top);     startactivity(i); 

that's when set the flag_activity_single_top property wont start new activity show activity intially created if not destroyed yet,

but if activity starting activity can put this

 <activity     android:name=".artistactivity"     android:label="artist"     android:launchmode="singletop"> </activity>
