Answer 1

You need to generate key with your release keystore and add that key to your facebook app.

Answer 2

You have require to set signed SHA key in your facebook developer console, you can directly generate signed and unsigned SHA using following code,

try {
            Logger.print("=" + getPackageName());
            PackageInfo info = getPackageManager().getPackageInfo(getPackageName(), PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Logger.print("KeyHash:" + Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
        } catch (PackageManager.NameNotFoundException | NoSuchAlgorithmException e) {
            e.printStackTrace();
        }

For the signed SHA install signed apk in your device and check log and unsigned install debug apk and check Log.
