Question

I’m writting app integrated with facebook. I want to post to wall without post dialog. I try to use code from this answer, but I got an error

{"error":
    {"message":"An active access token must be used to query information about the current user.",
     "type":"OAuthException",
     "code":2500
    }
}

I login user with this code

    public void authorize() {
    mFacebook.authorize(mActivity, new String[] { "publish_stream" }, new DialogListener() {
        @Override
        public void onComplete(Bundle values) {
            SharedPreferences.Editor editor = mPrefs.edit();
            editor.putString("access_token", mFacebook.getAccessToken());
            editor.putLong("access_expires", mFacebook.getAccessExpires());
            editor.commit();

            mLoginStateView.setImageResource(mAuthorizedDrawableRes);
        }

        @Override
        public void onFacebookError(FacebookError error) {}

        @Override
        public void onError(DialogError e) {}

        @Override
        public void onCancel() {}
    });
}

Please, explain me what am I doing wrong?

[ADDED]

If I try to post with mFacebook.dialog(currentActivity, "stream.publish", params, new UpdateStatusListener()); it works. Please, help me!

Oh, I’ve done it. But it looks like a bug or magic…
LogCat after authorize method (Facebook’s log is enabled)

Facebook-authorize: Login Success! access_token=AAAHL4f6XMS0BAHNJKpoGAUAeGDlynRt1s5XPdBPRWGfILGOTZB4OSEGi4HBPLZBXDWqK2RIO8disDtzxHBYSvL3bZAnHkU5hAVK9oqWhAZDZD expires=1356040438476

But then I try post with

String response = mFacebook.request("me/feed", parameters, "POST");

Function request from Facebook.java :

public String request(String graphPath, Bundle params, String httpMethod)
        throws FileNotFoundException, MalformedURLException, IOException {
params.putString("format", "json");
if (isSessionValid()) {
    params.putString(TOKEN, getAccessToken());
}
String url = (graphPath != null) ? GRAPH_BASE_URL + graphPath : RESTSERVER_URL;
return Util.openUrl(url, httpMethod, params);
}

I see in debugger, that Facebook’s function isSessionValid() returns false and mAccessToken = null. I don’t know why it is so, and why it returns true sometimes afterwards (yes, I understand that it is impossible). Explaine me, please, if you know.

This code solved my problem (it just re-sets access token)

if (!mFacebook.isSessionValid()){
    String token = mPrefs.getString("access_token", null);
    long expires = mPrefs.getLong("access_expires", 0);
    mFacebook.setAccessToken(token);
    mFacebook.setAccessExpires(expires);
}
Bundle parameters = new Bundle();
parameters.putString("message", msg);
parameters.putString("description", "test test test");
String response = mFacebook.request("me/feed", parameters, "POST");
if (response == null || response.equals("") || response.equals("false")) {
    Log.e(Const.LOG_TAG, "Blank response");
} else {
    Log.d(Const.LOG_TAG, response);
}
