public class FBActivity extends FragmentActivity {

    private LoginButton loginBtn;
    private Button postImageBtn;
    private Button updateStatusBtn;

    private TextView userName;

    private UiLifecycleHelper uiHelper;

    private static final List PERMISSIONS = Arrays.asList("publish_actions");

    private static String message = "Sample status posted from android app";

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        uiHelper = new UiLifecycleHelper(this, statusCallback);
        uiHelper.onCreate(savedInstanceState);

        setContentView(R.layout.activity_facebook);

        userName = (TextView) findViewById(R.id.user_name);
        loginBtn = (LoginButton) findViewById(R.id.fb_login_button);
        loginBtn.setUserInfoChangedCallback(new UserInfoChangedCallback() {
            @Override
            public void onUserInfoFetched(GraphUser user) {
                if (user != null) {
                    userName.setText("Hello, " + user.getName());
                } else {
                    userName.setText("You are not logged");
                }
            }
        });

        postImageBtn = (Button) findViewById(R.id.post_image);
        postImageBtn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View view) {
                postImage();
            }
        });

        updateStatusBtn = (Button) findViewById(R.id.update_status);
        updateStatusBtn.setOnClickListener(new OnClickListener() {

            @Override
            public void onClick(View v) {

            }
        });

        buttonsEnabled(false);
    }

    private Session.StatusCallback statusCallback = new Session.StatusCallback() {
        @Override
        public void call(Session session, SessionState state,
                Exception exception) {
            if (state.isOpened()) {
                buttonsEnabled(true);
                Log.d("FacebookSampleActivity", "Facebook session opened");
            } else if (state.isClosed()) {
                buttonsEnabled(false);
                Log.d("FacebookSampleActivity", "Facebook session closed");
            }
        }
    };

    public void buttonsEnabled(boolean isEnabled) {
        postImageBtn.setEnabled(isEnabled);
        updateStatusBtn.setEnabled(isEnabled);
    }

    public void postImage() {
        if (checkPermissions()) {
            Bitmap img = BitmapFactory.decodeResource(getResources(),
                    R.drawable.ic_launcher);
            Request uploadRequest = Request.newUploadPhotoRequest(
                    Session.getActiveSession(), img, new Request.Callback() {
                        @Override
                        public void onCompleted(Response response) {
                            Toast.makeText(FBActivity.this,
                                    "Photo uploaded successfully",
                                    Toast.LENGTH_LONG).show();
                        }
                    });
            uploadRequest.executeAsync();
        } else {
            requestPermissions();
        }
    }

    public void postStatusMessage() {
        if (checkPermissions()) {
            Request request = Request.newStatusUpdateRequest(
                    Session.getActiveSession(), message,
                    new Request.Callback() {
                        @Override
                        public void onCompleted(Response response) {
                            if (response.getError() == null)
                                Toast.makeText(FBActivity.this,
                                        "Status updated successfully",
                                        Toast.LENGTH_LONG).show();
                        }
                    });
            request.executeAsync();
        } else {
            requestPermissions();
        }
    }

    public boolean checkPermissions() {
        Session s = Session.getActiveSession();
        if (s != null) {
            return s.getPermissions().contains("publish_actions");
        } else
            return false;
    }

    public void requestPermissions() {
        Session s = Session.getActiveSession();
        if (s != null)
            s.requestNewPublishPermissions(new Session.NewPermissionsRequest(
                    this, PERMISSIONS));
    }

    @Override
    public void onResume() {
        super.onResume();
        uiHelper.onResume();
        buttonsEnabled(Session.getActiveSession().isOpened());
    }

    @Override
    public void onPause() {
        super.onPause();
        uiHelper.onPause();
    }

    @Override
    public void onDestroy() {
        super.onDestroy();
        uiHelper.onDestroy();
    }

    @Override
    public void onActivityResult(int requestCode, int resultCode, Intent data) {
        super.onActivityResult(requestCode, resultCode, data);
        uiHelper.onActivityResult(requestCode, resultCode, data);
    }

    @Override
    public void onSaveInstanceState(Bundle savedState) {
        super.onSaveInstanceState(savedState);
        uiHelper.onSaveInstanceState(savedState);
    }

}

This is complete code, which provides login, status update, image update to the point.
