I created the keys, where I create the application

where keys is now? (there is only one file LM.apk, but he did not keys)

Answer 1

You're are misundersting the keystore :

• The keystore is a file which identify you (to securize your release), don't name it *.apk, it's not your application build
• You can store as many key in your keystore, one for each application you want to sign with

So you just have to create a first key on your keystore by providing an alias and a password

Then you'll have 1 password for opening your keystore and one for signing with the desired key (alias)
