Re: [android-developers] Using startActivity( intent ) multiple times, fails.
I think this may well do the trick! Just when you think you've scoured the docs looking for the right answer, someone else goes and finds it for you :-) And the specific email app is what our client wants. Mind you, a chooser would be a better approach and are used elsewhere. Will see about convincing them of this, instead.

Re: [android-developers] Using startActivity( intent ) multiple times, fails.
Fantastic response, thanks! I knew I was missing something... turns out it's not just *one* thing I was missing, but a whole host of them. As I said in the other post, this was the decision made by the client, but would look to (and rather!) invoke a chooser for mail applications. With regards to the launching Intent, I'm clearly missing something as to the best approach for this, or at least, missing an understanding of the mechanisms Android employs in order to launch this. We only wanted to launch the Email client, be able to browse/check this, download some files and launch our application again. Is there actually a better approach? From what you're saying, I'm almost certainly doing it wrong - but am a little stumped as to the *right* way.
