Here is documentation on how to install Electrum on your Android device:

http://ecdsa.org/electrum/android.html

feedback is welcome

Im stuck at step 3. When I launch SL4A and scan the barcode, nothing happens. It keeps saying "no matches found".

maybe your barcode scanner does not accept large QR codes?
see here if you can update it: https://play.google.com/store/apps/details?id=com.google.zxing.client.android

alternatively, you can copy the file manually to your phone

It scans the barcode just fine. To be sure, I also tried with the scanner you linked, but I get the same result: nothing happens after scanning.
Im not sure how to manually copy the file to my phone or get it in SL4A either :/

Nevermind. What you have to do is click menu button, then preferences, show all files.
By default the .py files are hidden in SL4A!

Well, that didnt get me much further. Trying to run the scipt causes SL4A to crash instantly Sad

I suspect you did not install python for android... or you uninstalled it by mistake
edit: after step 2, you need to launch python for android and click the 'install' button

Effectively the same seed gives you the same series of receiving addresses on both machines and hence both clients can see all the transactions coming and going. The two wallets are automatically synchronized.

oh and it's implemented so nicely: if you have a desktop electrum, you can have it display the seed as a qr-code and scan that from your phone's electrum. awesome!

Hopefully this Electrum client will run on older versions of Android. Mobile phone operators are still selling Android 2.1 handsets at the cheaper end of the market.

I was disappointed that Bitcoin Spinner does not run on my new SonyEricsson Experia X8. How do they expect Bitcoin to make inroads into the african market if it doesnt run on the cheaper smart phones?

Electrum runs on my android 2.1 just fine. As long as there's sl4a and python, it should work.

Jan just said the next version of bitcoinspinner should, too.

Electrum is pretty clever . . .

You have a master seed from which it derives a series of private keys to use.

Given the seed you can work out all the receiving addresses you need.
ThomasV has implemented the same seed -> addresses algorithm for both his desktop and now an Android client.

Effectively the same seed gives you the same series of receiving addresses on both machines and hence both clients can see all the transactions coming and going. The two wallets are automatically synchronized.

Also to help remember the seed (which is the usual hex gobble-de-gook) he has a "12 word look up" which converts the seed to a phrase like:
horse throw yelp sneeze box house jump cloud seven when slope friend

that you can write down and put somewhere safe.

(I am hoping he has a secret parallel development to have an iPhone client too !!)

All good stuff.

Your wallet is not on your device, it is in the cloud, and the cloud used by Electrum is the Bitcoin blockchain!

What? Wallet stored in the Bitcoin blockchain ? Does this work like btcmsg ?

That's wonderful!

the code is already available on gitorious, but needs to be polished a bit.

And how does Electrum compare to.... BitcoinSpinner?

1. BitcoinSpinner relies on a closed-source server run by a single individual. Electrum servers are open source.
2. The BitcoinSpinner server uses user accounts to store master public key, addresses, balance. With Electrum you can use any server, instantly; it does not matter if the server has never seen you before.
3. Electrum is also a desktop client. And here comes the magic part of deterministic wallets: you can use the same wallet on your desktop and on your telephone. They remain synchronized, automatically. To illustrate this, here is a screenshot of the same wallet on my desktop: https://s3.ecdsa.org/Capture-Electrum+0.43c.png you can see that the history and balance are the same as on the android screenshot.
Your wallet is not on your device, it is in the cloud, and the cloud used by Electrum is the Bitcoin blockchain!
