Hi
I desperately tried to answer in a thread with the same subject.
https://bitcointalk.org/index.php?topic=240548.0

After a lot of tries and then some searching I found out that this forum has "Newbie restrictions"...

So, Lets explain my solution here:

First go to "Account Settings" in the Blockchain app, and write down your Identifier.
Next, go to https://blockchain.info and klick "Wallet", and then "Login now" button.
log in with your identifier and password.

Now you can send your bitcoins somewhere else!
This worked for me at least. It turned out that I had different identifiers for the web and for my android so what I did was to transfer my btc to the other identifier and then paired my android device with the latter. Now the app works fine for me.

Hope this helps.

any thankful btc can be sent to BTC 126tfYse4wZSsxxT93fMGz3WEdGPzYCfcc
