Facebook integration on Android fbconnect broken link

I am trying to implement Facebook integration into my Android app and it goes off and logs in to Facebook fine, but when it tries to pass the access token back to the app it just returns:

The webpage at fbconnect://success#access_token=[ACCESS TOKEN] might be temporarily down or it may have moved permanently to a new web address.

Obviously where [ACCESS TOKEN] is a long sequence of chars.

I have got the App ID correct and added the key hash to facebook. But what process could I have missed?

Code:

public class FacebookActivity extends Activity {

private static final String APP_ID = "[MY APP ID]";
private static final String[] PERMISSIONS = new String[] {"publish_stream"};

private static final String TOKEN = "access_token";
    private static final String EXPIRES = "expires_in";
    private static final String KEY = "facebook-credentials";

private Facebook facebook;
private String messageToPost;

public boolean saveCredentials(Facebook facebook) {
        Editor editor = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE).edit();
        editor.putString(TOKEN, facebook.getAccessToken());
        editor.putLong(EXPIRES, facebook.getAccessExpires());
        return editor.commit();
    }

    public boolean restoreCredentials(Facebook facebook) {
        SharedPreferences sharedPreferences = getApplicationContext().getSharedPreferences(KEY, Context.MODE_PRIVATE);
        facebook.setAccessToken(sharedPreferences.getString(TOKEN, null));
        facebook.setAccessExpires(sharedPreferences.getLong(EXPIRES, 0));
        return facebook.isSessionValid();
    }

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    facebook = new Facebook();
    restoreCredentials(facebook);

    requestWindowFeature(Window.FEATURE_NO_TITLE);

    setContentView(R.layout.activity_facebook);
