This is a great development. But they should consider making it a light-weight client as soon as possible.
From the description:
doesnt that mean I could pay something offline and after that somehow delete the queued transaction? At least with a little code modification? Who would trust such kind of payment?
Actually there is a need for a delete queued transaction function: when paying in a store and realizing beeing offline too late, the store might not accept my offline-payment (for reasons mentioned above) and then surely I dont want the transaction beeing completed later...

Transactions don't require an internet connection. They will complete when you reconnect.

Beautiful. Now I have an excuse to finally get an Android phone.
Let's hope people take heed of this before we have a rash of losses from mobile devices.

It's really aimed at keeping pocket change available for small day to day transactions since your phone could be stolen (just like a real wallet could be picked) and for that it's an excellent choice.

Noob question - On my PC the "block chain" data file is several hundred megabytes. How is it only 14mb on this mobile version?
Put a USD/BTC calculator on there so I can calculate how much I owe my friends for dinner and I'll pay them in bitcoin.
Better put a EUR/BTC calculator in there. there are much more people in the EU than in the US. Also the USD may be dead before the EUR is gone.

Awesome. Sent 0.01 BTC to myself and it showed up on the phone, still waiting to be cemented in a block.

So it should be dropping the blockchain on your SD card, not the internal memory.
All right, I installed the creature, and it does seem to drop the blockchain on the SD card. However, it still takes up 2.20 MB of the internal memory — and since a wallet is continuously growing, this is amount is likely to increase. I'm not convinced it's such a good idea to store the wallet in internal memory.
Cheers,
Seems like a fair point for older smartphones. I've raised an issue for it (https://github.com/barmstrong/bitcoin-android/issues/9).
I really hope this catches on. Awesome. Damn, I may just go out and buy a cellphone so I can use this. (Yes, I have never owned a cellphone.)

You guys are changing the world...
From the application wiki (https://github.com/barmstrong/bitcoin-android/wiki/Technical-Details):
"It's a full bitcoin client running on your phone. This means it keeps its own copy of the blockchain (currently about 14MB) which we store on your phone's SD card, and it doesn't need to communicate with a centralized server. Most phones have large SD cards (8GB or more is not uncommon) so storing 14MB isn't too bad. The wallet file is stored on the phone's internal memory instead since it quite small compared to the blockchain. We include a recent copy of the blockchain in the actual app package that you download from the Android Market so you don't need to download and build the whole thing from scratch. The first time you run it, it will contact nearby peers and update the included blockchain to the most recent version. This usually takes a minute or less over WiFi. After that, updates to the blockchain and transaction notifications should be near instantaneous (a few seconds) over 3G or WiFi."

22 MB? OMFG!
Hence the Wifi recommendation. Remember, it does include a recent block chain.
I'm not worried about my data plan, I'm worried about the very limited amount of internal memory on my HTC Desire…
Cheers,

this is awesome but I'm wondering, how can I make it use the testnet (your screenshots have testnet addresses)?
Have raised an issue with the development team for you: https://github.com/barmstrong/bitcoin-android/issues/7

New era has begun!
Wow, that's awesome
