Ok everything is solved!

I used this link: http://www.reddit.com/r/reddCoin/comments/2bkzgy/about_the_androidwallet/
It guides to: http://www.reddit.com/r/litecoin/comments/1rl7xx/need_help_importing_private_keys/
And in the second link everything is explained.

So for the nearest future - Android wallet doesn't work and nobody should use it
