Integrating Facebook Into Android

[miyudreams]

Hi,

I am having some problems display the Facebook dialog box for posting to the user's Facebook feed. I have a HUD button that is pressed to post scores to Facebook. I wrote the callbacks to hook it up to Android's java code based on the wiki tutorial: http://www.stonetrip.com/developer/wiki/index.php?title=Hooks_and_Callbacks

In the static callback function I tried a lot of stuff.

I used Facebook's Android tutorial.https://developers.facebook.com/docs/mobile/android/build/
I tried Facebook's Hackbook code.https://developers.facebook.com/docs/guides/mobile/android_hackbook/
I tried extending AsyncTask. http://www.vogella.com/articles/AndroidPerformance/article.html
http://stackoverflow.com/questions/9425732/androidruntime-java-lang-runtimeexception-cant-create-handler-inside-thread-t

Facebook Authorization has no problems. But it will never display the dialog box.

I tried Facebook.request and Facebook.dialog.
I tried "stream.publish," "me/feed," and "feed."

Code: Select all

try
{
  Bundle parameters = new Bundle();
  parameters.putString("description", "Hello, testing");// the message to post to the wall
  //facebookClient.dialog(oThis, "stream.publish", parameters, this);
  //Utility.mFacebook.request("me/feed", parameters, "POST");
  Utility.mFacebook.dialog(oThis, "feed", parameters, new UpdateStatusListener());
  Log.d( "FacebookManager", "Message posted successfully.");
}
catch (Exception e)
{
  // TODO: handle exception
  Log.d( "FacebookManager", "Message post failed: " + e.getMessage());
}


Here is an AsyncTask java code:

Code: Select all

package com.companyname.gamename.Hackbook;

import android.app.Activity;
import android.content.Context;
import android.content.SharedPreferences;
import android.os.AsyncTask;
import android.os.Bundle;
import android.os.Handler;
import android.util.AttributeSet;
import android.util.Log;


import com.facebook.android.DialogError;
import com.facebook.android.Facebook;
import com.facebook.android.FacebookError;
import com.facebook.android.Facebook.DialogListener;
import com.companyname.gamename.Hackbook.SessionEvents.AuthListener;
import com.companyname.gamename.Hackbook.SessionEvents.LogoutListener;


public class FacebookManager extends AsyncTask<String, Void, Integer>
{
   private Facebook mFb;
    private String[] mPermissions;
    private Activity mActivity;
   
    public FacebookManager(final Activity activity, final Facebook fb, final String[] permissions)
    {
        mActivity = activity;
        mFb = fb;
        mPermissions = permissions;
   
    }
   
   @Override
    protected Integer doInBackground(String... sParams)
    {
        int count = sParams.length;
       
        /*if (!mFb.isSessionValid())
        {           
             mFb.authorize(mActivity, mPermissions, new LoginDialogListener());
            return 1;
        }*/
       
        return 0;
    }


   @Override
   protected void onPostExecute(Integer result)
   {
      fbPopupFeed();
   }
   
    private void fbPopupFeed()
    {       
       try
        {
            Bundle parameters = new Bundle();
            parameters.putString("description", "Hello, testing");
            //facebookClient.dialog(Jams.this, "stream.publish", parameters, this);
            //mFb.request("me/feed", parameters, "POST");
            //mFb.dialog(mActivity, "feed", parameters, new UpdateStatusListener());
            //mFb.dialog(mActivity, "me/feed", parameters, new UpdateStatusListener());
            mFb.dialog(mActivity, "stream.publish", parameters, new UpdateStatusListener());
            Log.d( "FacebookManager", "Message posted successfully.");
        }
        catch (Exception e)
        {
            // TODO: handle exception
           Log.d( "FacebookManager", "Message post failed: " + e.getMessage());
        }
    }
   
    /*
     * callback for the feed dialog which updates the profile status
     */
    public class UpdateStatusListener implements DialogListener 
    {
        @Override
        public void onComplete(Bundle values)
        {
            final String postId = values.getString("post_id");
            if (postId != null)
            {
               Log.d ( "FacebookManager", "Successfully posted." ) ;
            }
            else
            {
               Log.d ( "FacebookManager", "No Posts Made" ) ;
            }
        }

        @Override
        public void onCancel()
        {
           
        }
       
        @Override
        public void onFacebookError(FacebookError e) {
            e.printStackTrace();
        }

        @Override
        public void onError(DialogError e) {
            e.printStackTrace();
        }

    }
}


In the game file's .java file, I created an instance in "onCreate":

mFacebookManager = new FacebookManager(this, Utility.mFacebook, mPermissions);

In the callback function:
public static int fbShareScores( String sBody )
{
Log.d( Globals.sApplicationName, "fbShareScores: " + sBody);

oThis.mFacebookManager.execute(sBody);
return 0;
}

Please assist.
Thank you

This is honestly a better question for stackoverflow.com.

The question is whether your onPostExecute is ever called. If it is then there's an issue with the facebook dialog, possibly to do with context I would guess. Try throwing up a toast in onPostExecute with the same context and see if it shows up.

The answer probably is, because facebook is pure cra#
You download the official sdk, and then find out hours later that it's full of bugs or not yet released/live functions which lead to all kinds of errors.

We started playing around with it 2 weeks ago, and had to manually patch some facebook files in order to get them to work.
I'll try to get the changes and post em in the next week or so ...

I'm glad to know someone else has tried it. onPostExecute does get called. I'll have to look into the Facebook SDK if you are suggesting that there's bugs in the SDK. Thanks for the tips! If you have a chance to post some code, that will be helpful.

I managed to get Facebook up and running on my Android device and emulators. I noticed the game's .java file was using runOnUiThread, and this ended up working for me. No need to make any Facebook SDK changes. No need to extend AsyncTask.

See some sample code in this post: http://facebook.stackoverflow.com/questions/10427148/android-app-crashes-after-sharing-using-facebook-dialogs/10441776#10441776

Hope it saves other people from some headaches.

Also good to know: if you get a blank (all white) permission screen (after authorization) you may have to patch the facebook sdk using this: https://github.com/ksperling/facebook-android-sdk/tree/ssl_errors - caused a lot of trouble for us.
