title: Launching activities within a tab in Android
body: <p>Here's the deal. I have an application with three tabs. Through various interactions with the items in the tabs I end up launching other activities. The client has reviewed this and would like the activities launched "within" the tabs, so the tabs remain visible and if the user clicks the tab it goes back to the original activity defined in the setContent function. Is this possible and how would I go about this from other activities? (ie the child activities, not the one that defines the TabHost and has access to call setContent)?</p>
