The key that i get from the app as an error is different from the key i have declared in Facebook developers

Answer 1

The key that is displayed in your error logs is the app signature sent by facebook. All you need to do is copy this key and paste it in your app dashboard,android app key_hash section.

Answer 2

Generate a SHA1, this link can help you. Generating SHA1

Answer 3

Make sure to set the key on the developers site (Native Android App Key Hash) to the hash of your signing cert. This is different than the API key.

See the instructions here, Step 4: Add app signature to the Facebook App https://developers.facebook.com/docs/mobile/android/sso/

Es2Fbgrno9htovlX6FcXiex6u0I is your hash - set the "Android Key Hash" to this value on the site.
