How to open new activity from widget without showing old ones from activity stack?

Question

There're two activities in my app: A and B. A is opened in a usual way (from launcher). B is opened from widget. Also B has "dialog" theme, so I can see what's under it.

When app isn't runned and I open B from widget, everything is correct and I see launcher under B.

When app is runned and I open B from widget, I see A under it. But I need launcher to be under B, not A. How to get this?

UPDATE 1

Here's what I get (when I click the widget)

And here's what I need

you probably want to launch this activity with the following flags:

FLAG_ACTIVITY_NEW_TASK and FLAG_ACTIVITY_NO_HISTORY

so on your widget intent you add them as normal:

intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK |
                Intent.FLAG_ACTIVITY_NO_HISTORY);

Doesn't help. There's still A under B – kandi Jul 14 '15 at 18:04

Try to build your PendingIntent using TaskStackBuilder from the support library.

Alternatively, add these flags to your Intent:

Intent.FLAG_ACTIVITY_NEW_TASK |
            Intent.FLAG_ACTIVITY_CLEAR_TASK |
            Intent.FLAG_ACTIVITY_TASK_ON_HOME

My solution.

Use this
Finish the A (I've static field in A which stores its instance. So I just use a.finish())
simply startActivity() (don't forget about Intent.FLAG_ACTIVITY_NEW_TASK)
