Android Facebook Api Exception - remote_app_id does not match stored id

Question

I have an issue as said in the title of this post. I am unable to login.

SessionState currentstate =  session.getState();

gives me a state CLOSED_LOGIN_FAILED. I took a look at this post, Android Facebook SDK 3.0 gives "remote_app_id does not match stored id" while logging in

I generated a key using the keytool and put that in the App Dashboard. But that does not seem to help. Any help on this appreciated

Answer 1

call this below method from oncreate of your activity , it will print a hash key in logcat, add that into hash field in app setting on Facebook. try again it will work

  public void printHashKey() {

        try {
            PackageInfo info = getPackageManager().getPackageInfo("your.package.name",
                    PackageManager.GET_SIGNATURES);
            for (Signature signature : info.signatures) {
                MessageDigest md = MessageDigest.getInstance("SHA");
                md.update(signature.toByteArray());
                Log.d("TEMPTAGHASH KEY:",
                        Base64.encodeToString(md.digest(), Base64.DEFAULT));
            }
        } catch (NameNotFoundException e) {

        } catch (NoSuchAlgorithmException e) {

        }

    }
