Facebook SDK invalid Hash Key

Question

I'm writing an android application with my friend. In the application we use Facebook SDK and a login button. We already setup the hash key using the code similar to what facebook suggests Code in the app profile in facebook. We also wrote the key under Settings -> Key Hashes. When testing the login on real device , if the native facebook app is using my friends account our application can login , but if i use my account I get the error :

Invalid key hash . The key hash XXXXXXXXX.... doesn't not match any stored key hashes . configure your app key hashes at ......

We checked in the application profile and my account is also written there with Admin privileges.

Run this code in your application and you will have the Hash Key:

try
{
    //paste Your package name at the first parameter
    PackageInfo info = getPackageManager().getPackageInfo("PUT_YOUR_PACKAGE_NAME_HERE",
            PackageManager.GET_SIGNATURES);
    for (android.content.pm.Signature signature : info.signatures)
    {
        MessageDigest md = MessageDigest.getInstance("SHA");
        md.update(signature.toByteArray());
        String sign = Base64.encodeToString(md.digest(), Base64.DEFAULT);
        Log.e("MY KEY HASH:", sign);
        Toast.makeText(getApplicationContext(), sign, Toast.LENGTH_LONG).show();
    }
}
catch (PackageManager.NameNotFoundException e)
{
}
catch (NoSuchAlgorithmException e)
{
}

For a full facebook login example see this answer.

Since you are logging from other devices, you should enable your app in the facebook console. Check this answer to see how.

Please enable your application if you haven't yet. I edited my answer. – Menelaos Kotsollaris May 02 '15 at 11:49
If the above does not fix your problem, you should delete your application from the `facebook console` and do the process from the begining as it might have bugged out. – Menelaos Kotsollaris May 02 '15 at 12:04

Make sure you're using the correct password as keytool apparently doesn't reject an incorrect one and will generate an incorrect hash. The default keystore password is android
