Its all about session management.

//Check for active session -
Session session = Session.getActiveSession();

// if it doesnt exist create one-
if(session ==null)
session= new Session(getApplicationContext) 

// if it is not open open it first

    if (!session.isOpened() && !session.isClosed()) {
        session.openForRead(new Session.OpenRequest(this)
        .setPermissions(Arrays.asList("basic_info"))
        .setCallback(statusCallback));
    }
    else
    {
        Session.openActiveSession(getActivity(), this, true, statusCallback);
    }

    // callback listner fires when session state changes
    private class SessionStatusCallback implements Session.StatusCallback {
        @Override
        public void call(Session session, SessionState state, Exception exception) {
            //If your session is opened
            if(session.isOpened()
              publishData(session);
        } 

Method to publish your request -

    public void publishData(Session session)
    {
     OpenRequest open = new OpenRequest(this);
            open.setLoginBehavior(SessionLoginBehavior.SUPPRESS_SSO);
            open.setPermissions(Arrays.asList(new String[]{"email", "publish_actions", "user_birthday", "user_hometown"}));
            open.setCallback(this);
                    session.openForPublish(open);
    }

publishData defination can also be -

public void publishData(Session session)
        {
Bundle params = new Bundle();

params.putByteArray("message", "some message".egtBytes());
params.putByteArray("name", "some name".getBytes());
params.putByteArray("link", "some link".getBytes());
params.putByteArray("description", "Some description".getBytes());
params.putByteArray("picture", "picture.url".getBytes());

Request postToWall = Request.newRestRequest(session, 
                                                    "/" + pickedUsersId.get(0) + "/feed", params, HttpMethod.POST);
postToWall.setCallback( new Request.Callback() 
{

    @Override
    public void onCompleted(Response response) 
    {
         // get response
        Log.e(TAG, response.toString());

    }
});
Request.executeBatchAsync(postToWall);
}
