I have two similar question,

1.
I have a TabActivity, and when I select one specific tab I want to display one of two candidates activities. And it depends on run-time. i.e. I want to display two different activity in one tab dynamically due to different mode.

For more detail description,
It’s like a social platform, user may belong to a group or not.
If he belongs to a group, when he select “GroupTab”, he can see a activity page for group info.

If he does not belong to any group, when he select “GroupTab”, he can see a list of all available groups.

He can join or quit a group dynamically, so the GroupTab’s content is depend on run-time.

2.
When I press a button in a activity (which is in a Tab), I want to change to next activity, and that activity could go backward to original activity too. (All activities should be under the Tab)

I’ve seen some method using ActivityGroup, and since it is deprecated, I’m looking for some other alternative way to implement that.
Any solution?

    EDIT: For your first question. I’m thiking that you can use the OnTabChangeListener and then check what tab is currently selected and based on that check if a user belongs to a group or not.

    For question two, Fragment is the way to go. There’s a post on it here: http://android-developers.blogspot.com/2011/02/android-30-fragments-api.html

    EDIT: You will have to install the compatibility package to use Fragments in Android < 3.0
