android facebook publish photo

After looking on the net for 2 days I finally decided to post on SO.

Well I simply want to publish a photo in my android app on to facebook.

AM using the official android-facebook-sdk. I imported to example project and in the upload section add my code to upload photo. like

mUploadButton.setOnClickListener(new OnClickListener() {
    public void onClick(View v) {
        Bundle params = new Bundle();
        params.putString("method", "photos.upload");

        Bitmap temp = BitmapFactory.decodeResource(getResources(),R.drawable.facebook_icon);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        temp.compress(Bitmap.CompressFormat.JPEG, 100, baos);
        byte[] imgData = baos.toByteArray();

        params.putByteArray("picture", imgData);
        mAsyncRunner.request(null, params, "POST", new SampleUploadListener());
    }
});

But it doent work :(

I went through the links in this forum too like: Looking for android Facebook SDK examples

Looking for android Facebook SDK examples

EDIT: Just got this working. This is in the ShareOnFacebook class under the postToWall() function.

byte[] data = null;

Bitmap bi = BitmapFactory.decodeFile(photoToPost);
ByteArrayOutputStream baos = new ByteArrayOutputStream();
bi.compress(Bitmap.CompressFormat.JPEG, 100, baos);
data = baos.toByteArray();

Bundle params = new Bundle();
params.putString("method", "photos.upload");
params.putByteArray("picture", data);

AsyncFacebookRunner mAsyncRunner = new AsyncFacebookRunner(facebook);
mAsyncRunner.request(null, params, "POST", new SampleUploadListener(), null);

EDIT:

When making the Intent:

result is the path to the image on the device.

Intent postOnFacebookWallIntent = new Intent(getApplicationContext(), ShareOnFacebook.class);
postOnFacebookWallIntent.putExtra("facebookMessage", facebookMessage);
postOnFacebookWallIntent.putExtra("facebookPhoto", result);
startActivity(postOnFacebookWallIntent);
