Re: [android-developers] Can I prelaunch an app?

Hm, it's not really clear what you mean here.

Apps have a kind of dynamic "living forever" feeling to them. You get
a 'poke' (your onStart(), etc...) gets called when you send an intent
to fire up the app on it's main screen. If you're asking if there is
any intent that allows you to bring up an app into memory and position
it so that it's lying in the background waiting to come back to with
an onResume(), the answer is no. However, you *can* send an intent
which is caught by a broadcast receiver or a service within the app.
This will effectively bring it into memory, but not an associated
screen.

What is the use case for this? I can imagine that it's possible to do
something annoying "pop under" thing, but the fact that the framework
doesn't support the kind of thing I just mentioned also implies that
what you really want to do should be able to be accomplished by some
other means..
