facebook authentication error in release.apk in android

Question

I have created released apk for my android app. I have created the keystore and signed the app with it. Google Plus authentication is working fine but I am facing problems with facebook authentication.

I am getting the following message while trying to authenticate app with facebook...

I have added the provided keyhash to facebook developers' settings. But still I am getting the same error message.

Can anyone tell me how should I solve this issue?

Answer 1

Goto to developer settings for your app on facebook and add the Key Hashes shown in the above error manually under settings>basic>Key Hashes. Then try running your app

Answer 2

Try this link Facebook android app error : Invalid key hash

I had a similar problem and it turned out that there was an upper case letter I which is similar to lower case letter l, inside this link you will find a code that can get the key hash, use Log to show it inside the console and copy paste it, it will do the trick.
