It’s funny I found this exactly today, I just posted about my twitter client http://underdev.org/2007/11/21/announcing-twitteroid/
I had a look at your code, I was unaware of the requestqueue and ended up doing it myself, well it was a good exercise.
Cheers.

Great little app! I’m quite suprised how short and easy the actual final code is. Though the hardest part is the UI I guess. As MikeR says, can you put the correct version of AndroidManifest.xml in your zip? The one that’s there is corrupt (is actually indeed a zip file). Thanks!
