Can one APK result in multiple icons/apps on the device?

 Hi all,

Curious if this functionality is present on the Android platform.  I'm
looking to package my apps into a single APK file, which when
installed would spawn multiple application icons on the device.  All
applications would be related and would talk to each other (this part
isn't a problem and is working fine).

Can I package multiple related apps in a single APK install file?

Thanks

That depends on what you mean by "app".

If you mean multiple icons in the Launcher, sure, no problem. Just have
all such activities have the standard intent-filter with <action
android:name="android.intent.action.MAIN" /> and <category
android:name="android.intent.category.LAUNCHER" />. Every activity with
that intent filter will show up with an icon.

If you want multiple entries in the Manage Applications list in
Settings, though, that cannot be done AFAIK.

In Android, an app = APK. What you are really creating with the multiple
icons is a single app with multiple user-initiated entry points.

Can one APK result in multiple icons/apps on the device?

 'm trying to do the same thing as the original poster: That is, have
one APK, resulting in multiple icons in the Launcher app tray, each
icon launching a different Activity within my APK. Seems like a simple
thing, but it's not working for me.

I've posted my AndroidManifest.xml below. The behavior I'm seeing is
that I indeed get two icons in the Launcher app tray -- an icon for
Foobar1, and another icon for Foobar2. Both icons work as expected if
they're the first thing I click. That is, icon Foobar1 launches
Activity Foobar1, and icon Foobar2 launches Activity Foobar2.

However, if I launch Foobar1, then hit the home key (not the back
key!), then try to launch Foobar2, what I get is Foobar1 -- and vice
versa.

It seems like if either Foobar1 or Foobar2 are already instantiated
within the app's task, and I go back to the Launcher and attempt to
launch either Foobar1 or Foobar2, the Launcher simply brings my
already existing task to the foreground showing whatever Activity was
previously on top.

Any pointers? Thanks!

  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!
