The wallet doesn't have coins in; it has keys in.  Therefore it doesn't matter how many coins are in that wallet when it is uploaded; it matters how many might be in it in the future.  It doesn't matter that it will be encrypted in the future, it matters that it's not encrypted now.

This is a great point, and we'd most likely force the creation of new receive addresses (and therefore keys) as part of an upgrade.  I believe this would solve it no?

You can also just uninstall the app (sending your coins somewhere safe first) and reinstall a new copy once encryption comes out to get brand new wallet.

We certainly don't have it all figured out yet.  Thanks for bringing this up.

What happens if i use it on 2 phones? I guess the wallet backup will get messed up if i use the same google account on both phones, right?

We actually haven't tested this yet.  In theory it should keep the wallet synced between the two phones correctly (Android is pretty good at this in general).  But I can't say for sure without testing it first.  Some additional logic might be needed.

Is it possible to play with this on testnet?

No, we don't currently have an option for this.  But you could build a testnet app using the source from github (if you have an Android development environment setup with Eclipse etc): https://github.com/barmstrong/bitcoin-android

There is a simple boolean flag in ApplicationState.java

We should probably put up a testnet version on github or the Android Market.

Does it have an automatic amount for the transaction fee? I remember an app a little while ago that appeared to have a built in transaction fee of .01 btc.

No transaction fees are added.  Would be a nice option.

Did anyone figure out where the wallet.dat file is stored on the phone yet? Mine started forceclosing all of a sudden, and I want to back the wallet up before uninstalling and reinstalling the app, just in case when I uninstall it wipes my wallet with the brand new shiny Bitcoin in it :/

Yes it keeps the wallet on the phones internal memory.

How do I know that it's actually making progress downloading the blockchain?  And why not have a regularly updated app that is really just an archive of the blockchain headers?

I'm actually trying to determine that.

This is a great point, and we'd most likely force the creation of new receive addresses (and therefore keys) as part of an upgrade.  I believe this would solve it no?

You'd have to make sure you blanked all the pre-created addresses too; and of course that you didn't overwrite existing addresses which might have credit on them.  Then warn the user that they should transfer all the credit they have on those current addresses to one of the new, safe, ones.

That would probably do it.

I do like the idea of a wallet that is part of my google account; but I don't trust google enough to put real money in a place where I have to trust every employee who has access to their cloud storage (which will be a huge number of them).  The ideal solution then is a shared wallet with strong encryption using a password that I have to enter before sending any bitcoins.

It's still not perfect because you're relying on computing power never increasing sufficiently that your current secure password becomes insecure in the future.  Therefore you also need an option to not share the wallet in the cloud, and allow me to back it up manually should I so choose.

If you want to play on testnet, you should try Bitcoin Wallet for Android:

https://market.android.com/details?id=de.schildbach.wallet

It is open source, you can compile it for prodnet as well. I am searching for developers, translators and testers:

http://code.google.com/p/bitcoin-wallet/

Cheers,

Andreas

I was hoping for a directory, like /etc/....

This program looks awesome!

But the 'backup wallet to cloud' feature is exactly what will stop me from using it yet.

Am I wrong or do they have this part backwards??

Quote
When you want to transfer Bitcoins to another account, a QR code pops up on your smartphone’s screen. The other user simply scans the QR code with his or her phone, and the Bitcoins are transferred to the second phone’s account.

The phone that 'pops up' a QR code would be the receiver.
The person scanning a QR code would be the sender.

You would be correct.

How long does it take for the payment to get processed?

I'm thinking of using this in a shop. You need payment processing in less than 3 seconds.

Has anyone been able to get this to do any more than spin?  Mine has been running since yesterday, has a 22 meg footprint, and still hasn't seen the coins that I sent it.  I'm using a Samsung Intercept, but it doesn't force close like Bitcoin Wallet did.
