I have a problem when I try to login facebooj in my app with facebook. My app work good in simulator in Android Studio but after I uploaded my apk to Google Play and I try to login I get the following error: Invalid key hash. The key hash .... does not match any stored key hash. But in my simulator it works and I print my app key hash with some code and putted it in my Facebook Developer page.
If i delete my app from facebook applications and I login for first time, it works fine. But after I do a second login, I get the eroor "Invalid key hash" Help me please...
