I am currently trying to implement the MVP pattern on Android. However, I came to think about memory leaks (since the presenter holds a reference to the activity - the view). My question is, should I set the view of the presenter to null say onDestroy of the activity?
This is a problem because then a singleton class will hold a reference to Activity, which consequently prevents it from ever being garbage collected. When your Activity is destroyed, it will be useless to the user, but will still occupy memory (RAM). Apart from taking precious memory, the presenter might receive events like successful API response, which will trigger a view.doSomething method, which can cause crashes (working with destroyed Activity's UI is not something you should ever do, the Android framework will throw exceptions).
Generally, Presenters are not so widely scoped so it's not an issue. If your presenters are scoped to live longer than Activity, you need to manually set the view reference to null to solve the problem.
To solve the described issues, you need to use something like userRepository.clear() or eventbus.unsubscribe(this). The implementations of such methods should cancel all in-flight requests and remove the references to subscriber/listener (presenter).If you do it right, you don't even need to set presenter's view reference to null. Garbage collector is smart enough to figure out your Activity and Presenter objects are holding reference to each other, but no other component is holding reference to them and delete both of them from Memory.However, my recommendation is to do it anyway, since it's an easy operation which does not have to be repeated everywhere (can be done in BasePresenter class) and may save you if you forget to clear some reference manually.
If Presenter's lifetime is not longer then Activity's, there is no need to set view to null. The important part is to stop background thread where your presenter executes its work. If you stop Presenter's background thread in onDestroy, then the thread is terminated and doesn't keep a link to the Activity anymore. So both Activity and Presenter can be collected by GC soon.
when im the presenter (not the organizer) and sharing my screen, why am i not able to see a poll? Or more important the poll result? It is necessary for my presenter to respond on the results but its not working, they cant see the results.
Presenters can NOT see the poll questions and they can NOT see the results, unlike the audience. This is very unpractical, and currently the only solution seems to be to make the presenter organiser, which is obviously something we would like to avoid.
Presenter mode is working like a charm, when it's available. But for some reason it's not available for all documents in the same space, and I can't figure out if there's something in some documents that cancels out the option?
Also, when in presenter mode the URLs to anchor points within a document doesn't work. Is it not supposed to?
Is it possible that some of the pages have not been converted to the new editor? As I understand it presenter mode only works on pages that are constructed in the new editor. Here's a link to That info - present-your-page-with-presenter-mode . Unfortunately I do not have presenter mode on my instance where I can verify all of this.
Whenever I start a Powerpoint slideshow, the slideshow itself appears on monitor #1, and on monitor #2 I get a "presenter view". I can use the top-bar UI to switch between the two monitors (slideshow on #2, presenter view on #1) - that works fine. However, this setting doesn't persist.
March Meeting 2024 will allow attendees and presenters the choice between an in-person or virtual experience, both taking place March 3-8. Join us for an extra special week as we celebrate the 125th anniversary of APS.
This virtual session will provide you with detailed guidance on strategies and techniques that can help you craft a successful presentation. By attending the live offering of the webinar, you will have the opportunity to ask questions of the presenters and share any insights or lessons learned from your own experiences.
We encourage all OLC conference presenters to attend the live webinar, as you will learn critical logistical information for both onsite and virtual presentations. If you are unable to participate live, the recording will be made available.
Presenter(s) must register for APTA CSM. No honoraria, registration, or payment of expenses is provided to poster presenters. If you are only coming to CSM to present your poster, you will need to purchase an 'Exhibit Hall Only' pass available online closer to the conference date, or onsite. If you have guests you want to bring along to view your poster presentation, they must also purchase an Exhibit Hall Only pass to enter Exhibit Hall A.
Whether you are invited faculty or an abstract presenter, the following resources will help you along your journey as a participant in Heart Rhythm 2024. Scroll down for additional individualized resources per role.
I'm Chairing a session at HRS2024. How do I see who the presenters are in my session so that I can contact them?
Please view your chair invitation on our faculty management platform. Log in with your HRS ID and password. On the top navigation menu, select "Messages" then "Invitations" in the drop down menu. From here, you will see your list of sessions. For any with a Chair role, when viewing the invitation, you can select the "+" to the left of "Session Information" which will show you all presentations and invited faculty for that presentation. Their email addresses will also be provided so that you may contact them to prepare your session.
Faculty and presenters must upload their presentations to the online portal, Orchestrate. Login information will be emailed to you in March 2024. Your upload should be completed by May 8, 2024 to ensure successful upload and that the presentation will be available to present onsite.
What does the area we are presenting in Boston look like?
Oral abstract presentations will feature a head table and chairs on stage along with a podium. When it is your turn to present, please step up to the podium. You will have a podium microphone, a presenter view screen, and a slide advancer/mouse pointer. There will also be a confidence monitor down stage for you to follow along when you are not presenting.
However, the moderated poster sessions will all follow the same format. Each session is 90-minutes in length. This will include 9 total abstract presentations. Each abstract presenter is assigned a 5-minute time slot to present their science followed by 5 minutes of moderated discussion.
Session Chairs: Thank you for volunteering to chair a session. You can work with the presenters to introduce them and the presentations, to facilitate the Q & A, and to keep the session running smoothly. Please see our tips for moderators.
As a presenter, you are required to sign the NCTE Speaker Agreement. Please log in to the Speaker Service Center to sign the agreement, confirm your acceptance, and to see your session schedule. Login information was sent via email on August 7 and August 18, 2023. Please email NCTEe...@ncte.org if you did not receive this email.
The expectation is that all presenters are to register and attend the Convention in person. This request is out of respect for the attendees who will travel to Columbus expecting to see live presenters and to ensure a positive experience for the attendees.
