I'm finally getting ready to install an Android client. I believe Android Wallet is the most popular one.
How do I back up the bitcoins stored on it?
Also, is there a thin native Android client being developed?

P.S. I ended up using the Android version of Blockchain's MyWallet, which has built in backup to email/dropbox/google drive. – ripper234 May 27 '12 at 16:54

Andreas, once stored, how does this "private key" work as a backup tool? If my phone is lost, how can I retrieve the balance that was in the android wallet on my pc for example? – Tom Nov 03 '13 at 00:05

1@Tom - most clients support importing a private key (how to do this is client-specific) – ripper234 Nov 03 '13 at 09:41

I don´t consider SD-card to be external storage. Is it possible to backup to a connected PC or a cloud service – Jan 02 '14 at 17:37

Bitcoin Wallet for Android supports backing up your private keys to external storage (e.g. SD Card). Just select "Export/Import private keys" from the action bar overflow menu.

As with any backup solution you must test it yourself through the whole cycle first in a zero risk scenario.
Mycelium has an excellent backup solution which outputs a seed phrase for a HD wallet
You can then store this any way you wish, for example on paper in a physically secure location.

I think I'll wait for a good light client. I just wanted to play around with some coins on my android, but it's not urgent (I really don't have anywhere to spend them anyway at this point). – ripper234 Jan 10 '12 at 17:24

1Yes it takes an age to get started, even on a wifi connection. I think mine took over 24 hours. But after that it's sweet and I like to keep a few on there just in case. There are people beginning to accept them, and I couldn't miss the opportunity. Sometimes it's scary when the wallet becomes worth more than the hardware though! :-) – barrymac Jan 10 '12 at 17:31
