I think I have a solution figured out. As my limited understanding
goes, the launcher always launches Activities with
FLAG_ACTIVITY_NEW_TASK, which means the newly launched activity is
intended to be the root of a new task. However, if that task already
exists with a different Activity at its root, this doesn't work. So,
the solution to the example I pasted in my prior post with Activities
Foobar1 and Foobar2 would be to give those two Activities different
task affinities like so:
...
<activity android:name=".Foobar1" android:label="Foobar1"
android:taskAffinity=".Foobar1">
...
<activity android:name=".Foobar2" android:label="Foobar2"
android:taskAffinity=".Foobar2">
...
Clarifications would be welcome!
