Android debug keystore hash key failure in facebook

Question

I use Java 1.8 version and OpenSSL 1.0.2f.

But when I generate a hash key it will not match with Facebook hash key.

I regenerate an Android debug key manually and through Eclipse but no effect. My Google+ API is also not working.

I am using a MAC system.

try using my tool here : http://stackoverflow.com/questions/4388992/key-hash-for-android-facebook-app/17732453#17732453 — Shahar, Feb 13 '16 at 05:58

Try running the following code in your Activity's onCreate()

try {
    PackageInfo info = getPackageManager().getPackageInfo(
                           getPackageName(),
                           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 (NameNotFoundException e) {

}
catch (NoSuchAlgorithmException e) {

}

see if that gives you anything like my tool gives.

note that you should run the tool on the debug.keystore file, the same one that Android studio uses.

if it does, than it's the right one.
