Sharing wall posts on facebook android sdk

Question

Hi, I am new to Android programming. I want to share an image with some description on facebook. I tried to explain each method in answers to stackoverflow. My problem is to open the facebook dialog, but it does not have the package options set. Please help me with this. I have already tried almost 20 different pieces of code. Please give me a fully functional code.

    @Override
        public void onClick(View v) {
            fb = new Facebook(app_id);
            Bundle par = new Bundle();
            par.putString("name", "Ass");
            fb.dialog(con,"feed",par, new DialogListener(){

                @Override
                public void onCancel() {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onComplete(Bundle arg0) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onError(DialogError arg0) {
                    // TODO Auto-generated method stub

                }

                @Override
                public void onFacebookError(FacebookError arg0) {
                    // TODO Auto-generated method stub

                }});


        }
    });

}
