Facebook login error when app released publicly

Question

People have been successfully downloading my alpha phase app and logging in with Facebook. I just released it publicly and now people are getting errors logging in. Do I need to change anything to do with my app secret or hash keys once its public instead of in the alpha stage?

Answer 1

I had the same problem. its about the hash keys, when you sign an app the hash key is different. You can see the error, install your app from the market and see the log from facebook and you can see the error from hashkey.

For example first install your app from the playstore, then conect your cel and see the log when your are trying to logging with facebook, and you can see the next error:

as you can see you need to add the key YDJyZb3zqAYTsk5QiyGsrtNEEvRI= (you need to add "=" at the end).
