I\'m working on an Android app, in which I want to integrate a Facebook posting feature. I downloaded the Facebook-Android SDK, and I got the readme.md (text file) in there,
Solved mine too in Android Studio but with slight different approach.
To get the SHA-1 value in Android Studio.
SHA-1 value look like this CD:A1:EA:A3:5C:5C:68:FB:FA:0A:6B:E5:5A:72:64:DD:26:8D:44:84
and open http://tomeko.net/online_tools/hex_to_base64.php to convert your SHA1 value to base64. This is what Facebook requires get the generated hash " ********************= " and copy the key hash to the facebook app console.
