java.lang.UnsupportedOperationException: Session: an attempt was made to request new permissions for a session that has a pending request

Question 1

Is there a particular reason you don't want to use the UiLifecycleHelper? That class is there specifically to make your life easier, and so you don't run into problems like this.

If you must, the easiest way is to look at the code inside UiLifecycleHelper, and copy them to the appropriate methods in your Activity.

For your specific Activity, I see two things wrong:

You're not opening the Session at any time (you directly call requestNewPublishPermissions, but you need to open the session first). Calling "new Session" does not open it.
You're not overriding the onActivityResult method, which is necessary to pass information back to the active session.

Question 2

try the following code. it is simplest sample to post the update:

put the code after the seeson login in:

session.addCallback(new StatusCallback() {

    @Override
    public void call(Session session, SessionState state,
        Exception exception) {
        List<String> PERMISSIONS = Arrays
            .asList("publish_actions");
        session
            .requestNewPublishPermissions(new Session.NewPermissionsRequest(
                getActivity(), PERMISSIONS));

        Request request = Request.newStatusUpdateRequest(
            session, "Temple Hello Word Sample",
            new Request.Callback() {
                @Override
                public void onCompleted(Response response) {
                    L.d("fb:done = "
                        + response.getGraphObject() + ","
                        + response.getError());
                }
            });
        request.executeAsync();

    }

});
