How to extract a private key from a backup

[el kaka22]

I have used the Android wallet for almost a year but now it is running extremely slow and I can't spend the funds inside it now. I've abandoned that address now but there are still about 2mBTC stuck there and sometimes referral earnings from faucets also goes there. Can someone do that?

Do you know if your wallet was created with version 4.0 or higher (Released Oct 3, 2014)? If so, there may be an easier alternative....

My wallet was created back in June 2014 so why it is having many transactions and slowing down the app...

If you don't want to use your phone to empty the wallet, you can use these instructions to do it on your personal computer:

I won't reach my computer for a long period so that's why I use my phone to store my BTC. May I invite some trusted user here to extract the private key for me? However I would only pay 0.2mBTC to who helps me to do that because there is only 2mBTC there...

No one can do it? Or the reward is too low? I can increase the reward to 0.5mBTC now.
Also could a developer tell me what to do? Although the amount isn't too much, they are my hardly earned faucet earnings (previously) and my revenues from referring others. I do want to see my BTCs back.
