Android - Facebook Open Graph Share Dialog opens, then crashes

Question

I'm trying to open a Share Dialog inside my app with Open Graph, and it opens properly but after a few seconds crashes.

My code follows the documentation at https://developers.facebook.com/docs/android/share-dialog/#publish-og-with-user-objects but with slightly different constructors for createForPost, though I tried both ways.

private void shareToFB(Context context) {
    if (FacebookDialog.canPresentOpenGraphActionDialog(context.getApplicationContext(),
            FacebookDialog.OpenGraphActionDialogFeature.OG_ACTION_DIALOG)) {
        OpenGraphObject badge = OpenGraphObject.Factory.createForPost
                (OpenGraphObject.class, "exercisemeapp:badge", "I earned a new badge!",
                        "http://4sqday16.files.wordpress.com/2011/11/foursquare-gym-rat-badge.png",
                        null, "I completed a full body workout for 7 straight days!");
        OpenGraphAction action = GraphObject.Factory.create(OpenGraphAction.class);
        action.setProperty("badge", badge);
        action.setType("exercisemeapp:earn");

        FacebookDialog shareDialog = new FacebookDialog.OpenGraphActionDialogBuilder(getActivity(), action, "badge")
                .build();
        uiHelper.trackPendingDialogCall(shareDialog.present());
    } else {
        Toast.makeText(getActivity(), "Facebook not available", Toast.LENGTH_SHORT).show();
    }
}

The only errors I'm seeing in logcat are the following:

And the warning:

Exception during service com.facebook.http.protocol.ApiException:

Answer 1

Looks like your app's hash key and the one registered with facebook do not match. This is what facebook says.

Every Android app you'll create will be signed, and you will need to register each app's key hash with Facebook as a security check for authenticity
