I've had the Bitcoin Wallet for Android for some time. When I installed it I was assigned some public address/key. I have made various transactions in and out of the wallet but as fas as I can tell the address has not changed.
Does Android Wallet not transfer change from a transaction into a new address?
I actually don’t want it to do this. I want one fixed address I can use to send and receive coins. I also expected that the private key I backed-up early on would still be valid.
If change addresses are created does this mean I have to backup my keys after every transaction?
