I'm working on an update to the PMC Android Wallet.

The new version will have the option to import a private key by scanning (or pasting/entering) a private key. This is especially useful to redeem a paper wallet (ex: http://Preminer.com) or to use a vanity address.
BIP38-encrypted keys are supported, so any private key QR Code shown on a Paper Wallet can be scanned.

Disadvantages are:
- The whole blockchain must be reset. And it takes several minutes to re-download.
- Decrypting a BIP38 key takes about 30 seconds on an Xperia Z. It may take a long time on low-end devices.

Besides that, it's working OK. In a future version I'll try to improve these points. But I'm not sure it's even possible.

This is a new feature, not present in the original Bitcoin Wallet, so it needs to be deeply tested.

Tests should include:
- Importing a normal private key.
- Importing a BIP38-encrypted private key, which can be generated here.
- Trying to import an invalid key, or using an incorrect password.
- Verifying the funds of the imported address appear and can be spent.
- Overall checking.
- Suggestions to make it more user friendly.

If you have an Android device and can help me testing it, please PM me. If you don't have any PMC, I can send one to your paper wallet so you can test it.
