import com.facebook.android.*;
import com.facebook.android.Facebook.*;


public class MyActivity extends Activity {
	private Facebook mFacebook = new Facebook("0123456", R.drawable.ic_fb);

			public void onComplete(Bundle values) {
				android.util.Log.i("#### FB", "onComplete");
				if (values.isEmpty()) {
					//"skip" clicked ?
					return;
				}

				// if facebookClient.authorize(...) was successful, this runs
				// this also runs after successful post
				// after posting, "post_id" is added to the values bundle
				// I use that to differentiate between a call from
				// faceBook.authorize(...) and a call from a successful post
				// is there a better way of doing this?

						parameters.putString("name", title);// the message to post to the wall
						parameters.putString("link", "http://www.example.com");// the message to post to the wall
						mFacebook.dialog(activity, "stream.publish", parameters, this);// "stream.publish" is an API call
