Sorry I've had to post here because I've only just signed up to the forum. I've been working on an Android App to retrieve Bitcoin price information from Bitcoin Charts and thought I'd make it available to everyone. Hopefully you may find it useful or may want to comment.
The App connects to Bitcoin Charts service on start up and downloads the current prices. If you bring up the menu you can manually update the prices and selecting an exchange displays the full details of the exchange. Bitcoin Charts request that updates occur at a maximum of every 15 minutes but since this is a manual process I don't think that will be a problem. In the next version I want to look at automatically updating every 15 minutes, keeping a history on the phone. I'd also like to have a favourites list and the ability to configure alarms for prices rising or falling beyond a configurable threshold. I've tested the app on 2.2, 2.3 and 1.6 using the emulator.
It can be downloaded from the link below where you will also find a couple of screenshots:https://sites.google.com/a/lostdroids.net/lostdroids/applications

I'm afraid you will need to enable Third Party Apps to install until I get a Market Account. I've kept the permissions to a minimum though.
If you like this App, find it useful and want to keep me motivated working on it then please consider donating whatever you think it is worth to you :
