Coins Lost with Android Wallet (Andreas Schildbach)

[wyodude]

Just lost BTC2.69 on my Galaxy 2 with Bitcoin Wallet.

Here is what happened:

The phone is rooted, I had to re-install the ROM, after installing the Bitcoin Wallet app I've imported the private key from automatic key back up dated Nov 3.
After refreshing the blockchain all of the transactions seems to be back except one. The missing transaction was done on Nov 11, according to the exchange records. It has completed just fine and the balance was reflected all this time until today. Now I do remember creating a new public address for the transaction which is missing from the list after restore. The public address for the transaction is: 1Em2UPmydJuqxaVgGJfwtDLFBGYbpgMGjP

Also all the transactions after the Nov 11 appear to be fine, though none of them to the address in question.

Any ideas what can be done to restore the missing BTC?

Just trying to understand. You sent coins from one key of the app to another key in the same app? That's a usecase the app has got no good UI support for. Did you copy the address to the clipboard? Maybe something went wrong at that point?

When you re-installed the ROM, did it remove the app? If so, how can you have any automatic backups left? Automatic backups are written in the same app-private storage as the wallet file itself. If the wallet file is gone, the automatic backups should be gone too.

My guess is you picked an old backup. Don't go for the file created/modified dates. The date in the file name of manual backups is more reliable.

Thank you for replying.
Coins were sent from an exchange to the android wallet(new address to receive the coins were created)
Coins came in fine and were in the wallet from Nov 11 until Nov 21.
When I re-installed the ROM, I have restored the wallet using the Titanium BackUp. At this point wallet was restored, after the block-chain loaded coins from that transaction end up missing. All before and after transactions are fine but in the list of addresses that new address is missing so are the coins. Transactions after Nov 11 were outgoing transactions only. Not sure if I am explaining myself proper...

Also I have tried to restore the private keys from the back up. The most current one is dated Nov 3 (not manual). Any keys back up prior to August have transaction records going to Aug 13 and nothing after that. The Nov 3 automatic back up, restores all the transactions but the one that has that new wallet address.
Thank you again for your reply.

So you created a new address on 11 Nov to recieve payment from  the exchange site , But you didnt created new backup and you only have backup of 3 nov. Right?

That is correct.

Just greate a new adress again, this will be the same as you created before you made a backup and your app will check it on the blockchain and the coins will be available again.

Hu? When adding addresses, they are of course created randomly.

[wyodude]

Yep, they are created randomly. I guess it's my loss now. Will have to remember to manually back up the wallet after each transaction from now on or at least check that auto backup was performed.

[Andreas Schildbach]

Well, the app has an in-app backup reminder that tells you when its needed to back up the wallet. Keep an eye on the bottom of the main screen. Normally, you only need to refresh your backup when you have added a key.

Somehow I thought Android Wallet was a deterministic wallet?  Is it not, then?

EDIT: Ah, nm, I found the answer in another thread.  I obviously made some incorrect assumptions.

[Mike Hearn]

Not yet. I'm working on that.
