I lost my phone where I had my bitcoin wallet app (this one https://play.google.com/store/apps/details?id=de.schildbach.wallet ), I have a backup of the private keys on my PC but I don't know how to import them, the file is not wallet.dat
How can I restore my wallet?

use multibit - i used this wallet to import my private keys

Any wallet but bitcoin-qt will have a sweep key function.  Don't import them because whoever found your phone may have them.  Of course, make sure to backup your new keys.  I'd recommend electrum instead of multibit.

It's an encrypted file, which contains your private keys (in WIF format) when decrypted.

To decrypt: run "openssl enc -d -aes-256-cbc -a -in <filename>", where <filename> is the name of your wallet backup file.

You might be able to do it with an online tool that decrypts base64 aes-256-cbc (or one that decrypts base64, then another that decrypts aes-256-cbc), but I'd be wary of using one for a wallet. If you have a linux computer available, it's extremely easy to do.

Do what Dare said, Or If you have any other android phone, simply use it to import that backup wallet.

I have another android phone, how do I import the backup?

Open the wallet app, hit the menu button, tap "Safety", then tap "Restore wallet" and select the backup file and enter the password for it. The backup will overwrite your current wallet though, so be careful.

My advice was from when I had to restore mine a while ago, before that feature was in the app; I didn't know they had added the ability to restore wallets until now, it's probably the better way to go unless you have a computer with openssl on it handy. You should still send the coins from the backup to a different address though, as whoever finds your other phone will also have access to its wallet.

Thanks a lot, the only problem now is that I don't remember the password of the backup file, but probably I have written it somewhere.

Thanks again to everybody.

Happy to help, and good luck finding your password!

Are there any security measures to take when  you use your wallet on a smartphone ? Also, is it possible to use your smartphone has an added security layer for your wallet ? Like 2FA or something. If so, does your wallet need 3G or 4G ? Does it need to be with a ISP like AT&T ?

Well since you had a back up and wallet was encrypted your coins are safe, and even usable provided you can recall password :)

If your wallet is on your smartphone then having 2FA is kind of pointless (with regards to security if you lose your smartphone) if that uses the same smartphone.

Simple... don't keep more money in your smartphones bitcoin wallet than you keep fiat in your real life wallet.

Can use blockchain.info app as a hot wallet for your phone, keep rest of coins in usual offline cold storage.

You should setup a remote lock and wipe service on your android phone. I thought it was a overkill before, but since we start having bitcoin wallets on mobile phones, there is an increasing need to keep our phone data secure.

Blockchain online wallet which can import the private key,you can restore your wallet.

Bitcoin-qt (now known as Bitcoin Core) also has the ability to sweep a key, it just has to be done from the console interface.
