I write with Corona SDK a mobile application that integrates with Facebook. So I created a Facebook application that App ID I use for integration.

In login session from mobile device, I received a error with response “android key ….”. The solution for the problem was to set a “Android Key Hash” in “Native Android App” of the application. But I don’t understand exactly what does mean “Android Key Hash” and what I did. Can somebody pleases explain me about?

Could I still receive the same error if I run an application on other device or this “Android Key Hash” is unique for all my application’s users?

    You wont get an error provided you use the correct hash key. You can generate one by using this command:

    keytool -exportcert -alias androiddebugkey -keystore ~/.android/debug.keystore | openssl sha1 -binary | openssl base64

    If you are getting an error at that point try using a non debug keystore to sign and/or take a look at this post from the Corona SDK forums; http://developer.coronalabs.com/forum/2012/03/20/facebook-and-android-key-hash
