Here is my facebook class, and its working very fine. Just try it, you will learn lots of things from Simple Facebook. Dont consider some unusual code from below.

public class IjoomerFacebookSharingActivity extends Activity {

        private SimpleFacebook simpleFacebook;
        private SimpleFacebookConfiguration.Builder simpleFacebookConfigurationBuilder;
        private SimpleFacebookConfiguration simpleFacebookConfiguration;

        private String IN_MESSAGE;
        private String IN_CAPTION;
        private String IN_NAME;
        private String IN_PICTURE;
        private String IN_LINK;
        private String IN_DESCRIPTION;
        @Override
        public String[] setTabItemNames() {
            return new String[0];
        }

        @Override
        public int setTabBarDividerResId() {
            return 0;
        }

        @Override
        public int setTabItemLayoutId() {
            return 0;
        }

        @Override
        public int[] setTabItemOnDrawables() {
            return new int[0];
        }

        @Override
        public int[] setTabItemOffDrawables() {
            return new int[0];
        }

        @Override
        public int[] setTabItemPressDrawables() {
            return new int[0];
        }

        @Override
        public void onCheckedChanged(RadioGroup radioGroup, int i) {

        }

        @Override
        public int setLayoutId() {
            return R.layout.facebook_main;
        }

        @Override
        public View setLayoutView() {
            return null;
        }

        @Override
        public int setHeaderLayoutId() {
            return 0;
        }

        @Override
        public int setFooterLayoutId() {
            return 0;
        }

        @Override
        public void initComponents() {
            simpleFacebook = SimpleFacebook.getInstance(this);
            simpleFacebookConfigurationBuilder = new SimpleFacebookConfiguration.Builder();
            simpleFacebookConfigurationBuilder.setAppId(getString(R.string.facebook_app_id));
            simpleFacebookConfigurationBuilder.setPermissions(new Permissions[]{Permissions.PUBLISH_ACTION,Permissions.PUBLISH_STREAM,Permissions.EMAIL,Permissions.BASIC_INFO,Permissions.USER_PHOTOS});
            simpleFacebookConfiguration = simpleFacebookConfigurationBuilder.build();
            SimpleFacebook.setConfiguration(simpleFacebookConfiguration);

        }

        @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data)
        {
            simpleFacebook.onActivityResult(this, requestCode, resultCode, data);
            super.onActivityResult(requestCode, resultCode, data);
        }

        @Override
        public void prepareViews() {
            getIntentData();
            if(simpleFacebook.isLogin()){
                publishFeed();
            }else{
                simpleFacebook.login(new OnLoginListener());
            }

        }

        private void getIntentData(){
            IN_MESSAGE = getIntent().getStringExtra("IN_MESSAGE")==null ?"":getIntent().getStringExtra("IN_MESSAGE");
            IN_CAPTION = getIntent().getStringExtra("IN_CAPTION")==null ?"":getIntent().getStringExtra("IN_CAPTION");
            IN_DESCRIPTION = getIntent().getStringExtra("IN_DESCRIPTION")==null ?"":getIntent().getStringExtra("IN_DESCRIPTION");

            IN_PICTURE = getIntent().getStringExtra("IN_PICTURE")==null ?"":getIntent().getStringExtra("IN_PICTURE");
            IN_LINK = getIntent().getStringExtra("IN_LINK")==null ?"":getIntent().getStringExtra("IN_LINK");
        }

        @Override
        public void setActionListeners() {

        }

        private void publishFeed(){
            final Feed feed = new Feed.Builder()
                    .setMessage(IN_MESSAGE)
                    .setName(IN_NAME)
                    .setCaption(IN_CAPTION)

                    .setLink(IN_LINK)
                    .build();
            simpleFacebook.publish(feed, new onPublishListener());
        }

        class OnLoginListener implements SimpleFacebook.OnLoginListener{


            @Override
