Invalid key hash error, even though the key matches

Question

I get the following error when I try to login with facebook in debug mode.

Eventhough it matches the one I specified in the Developer Settings.

The following code prints out te same key hash:

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

Result: D/KeyHash:﹕ attaFrbPASaeKhWnrt8/oNcqd8s=

I followed the guides closely on the facebook developers page, so I don't think there is any code missing.

Log in works perfectly when I generate a signed apk and installed that one on the device. It doesn't work in debug mode and I have no idea why. it's really annoying that I have to generate a signed apk just to test anything facebook related.

I tried using a brand new debug keystore, but it's doing the same thing.

Any helo would be appreaciated.

For now I solved it by using the debug key hash where the release key hash shhould be.
