Android Facebook SDK - problem with authorizeCallback ()

I have an Android app that, among other things, also publishes updates on Facebook.

I created my code according to this example and it works great. The only difference between my code and what is indicated in the link above is that I also expanded onActivityResult, as indicated on the official Facebook SDK for Android website.

    @Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    facebookClient.authorizeCallback(requestCode, resultCode, data);
}

Sometimes, however, I get a null pointer exception on the line where I call "facebook.authorizeCallback ()" inside the onActivityResult () method.

This has never happened on any of my mobile phones or emulators. However, I continue to receive user crash reports, mainly from Droid and T-Mobile myTouch 3G phones. I tried a lot, but could not reproduce the problem. Can any body understand what might be wrong?
