Bitcoin Wallet 3.0 available!

[elebit]

I'm seeing 1.7% on 2.1 and 4% on 2.2. Quite small numbers, but I think one of the most secure ways to use Bitcoin, especially for a newbie, is to use an old, cheap, android phone as a dedicated hardware wallet. However I think a lot of these phones won't be compatible with BW3.

You probably already know this, but I can recommend CyanogenMod for you old cheap Android handset. CyanogenMod 7 is Android 2.3 and works with a lot of cheap phones. It gave my phone a few years more usable lifetime by freeing up space for applications. Works perfectly and with a bit of handholding during install it's completely usable for novices too.

Thanks for the extra info Mike. It sounds like it is not worth the candle to get BW working on the older android os. As Elebit says - a lot of the old phones can be upgraded to run a more recent version of the OS so BW3 is compatible with many old devices - they just need an OS upgrade first. If you were going to use a phone as a dedicated hardware wallet, you'd probably want to wipe it first anyhow.

I'd also like a way to add a view only wallet, For checking the balance on a savings account!

Yeah, read-only wallets are planned. I figure it can be useful.

There is one this missing in android wallet and it really sucks.

Which is "You can't copy your wallet address" nor you can send your wallet address to your mail or anything else. If you want to give it to someone you need to manually check and write wallet address.


Ps: I tried it once then uninstalled it, it didn't worked on my tab not sure about cellphones.

Erm, why can't you? Just tap your address... press copy....

I did that but when i tried to paste in mail it didn't worked, I will try it again and post here if it works.

but still it will be good if client can give you address at pastebin or something else.

Go to "Request Bitcoins". From here, you can share your address via QR-code, NFC, mail or any mail-like intent or clipboard.

Just a technical question.

Does Bitcoin Wallet works like the Electrum?

I mean does it connects to Bitcoin Wallets servers to check the blockchain?

And if so who runs those servers?

Thank you.

It doesn't, that's the main idea of Bitcoin Wallet.

I yesterday released version 3.09, which - thanks to Matt and Mike's work on bitcoinj 0.9 - calculates transaction fees correctly. For most transactions, that means a fee of 0.0001 rather than the flat 0.0005 which was hardcoded before.

[erono]

new version loading faster and works great.

[bitzip]

I've been using Bitcoin Wallet 3.0 to recieve bitcoins from mining.  Simple interface.  It works great.

I have one problem, I need to send a signed message using my wallet.  Can Bitcoin Wallet 3.0 do this?    If so, how?
If not, can someone recommend a good android or window 7 based wallet that can.

Thanks

It currently can't do that. It's not hard to add but the question is, whether that's really a common feature to use on a phone or tablet? Also, what's the best user experience for that. It'd help to know more about what you want to do. Eg, are you sending a signed email? You want to sign a forum post? Or do you just need to prove that you own a particular address? If you just want to prove address ownership, then maybe a separate feature for that is the right way to go.

I've never heard of a wallet used to sign a message, but someone needs me to sign a message to prove to I own the shipping address.   

[Mike Hearn]

How does signing prove anything? You could put any address you like in there. Perhaps it's in case of a dispute?

Anyway, it will take some time to add that feature unless Andreas does it, like, this weekend (but I doubt it). So you may need to instead, send coins from your Android wallet to MultiBit on your desktop and then use MultiBit to sign and send the money onwards to its final location.

I was thinking the same thing about the address.  Thanks for your help.

Wallet encryption is on track but it still needs quite some work. For example, the internal backup system must be reimplemented (there is no point in encryption if the automatic backups remain unencrypted).

I will probably offer pin or password initially and experiment with NFC tags and other tokens.

any progress yet? especially with the pin?

[Andreas Schildbach]

The first thing that needs to happen is a wallet format that's suitable for backups. The old format doesn't support encrypted private keys. Here is the issue in the tracker. It should be quite easy to implement. Maybe someone would like to take the opportunity and start contributing to bitcoinj?

That ATM really needs to be able to scan QRcodes directly. Most wallets, even Bitcoin-Qt, cannot import private keys from paper wallets due to the large indexes it requires.

For now the best bet is to use blockchain.info or some other website that has computed the relevant indexes, then send it onwards to your mobile wallet.
