Key hash for Android-Facebook app

Question

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,

Answer 1

The simplest solution:

1. Don't add the hash key, implement everything else
2. When facebook login is pressed, you will get an error saying "Invalid key hash. The key hash "xxx" does not match any stored key. ..."
3. Open the facebook app dashboard and add the hash "xxx=" ("xxx" hash from the error + "=" sign)
