Images. Many apps have lots of them to show, whether downloaded from the Internet, cached on internal storage, or loaded from from system-supplied providers like contacts and media. Loading images properly can be very complicated, yet loading them improperly can exacerbate common problems, like running out of memory. Many developers turn to image loading libraries to handle this problem.

In this 45-minute webinar, we will look at some of the criteria to consider when choosing an image loading library. Then, we will do deep dives into the code for two apps that exemplify the use of such libraries. One app will look at using Picasso (along with Retrofit) to download Stack Overflow questions with their askers' avatars. The other app will populate a list with the videos on the device, complete with thumbnails loaded by the Universal Image Loader library.

This is an online event, hosted using a Dozeo meeting space. It should work on any desktop browser with Adobe Flash 11.5 support. Notably, this means that Linux users will likely need Google Chrome (not Chromium) to get the Flash support. You can check your system compatibility to confirm that your browser should work. Audio for the presentation will also be online, so speakers or headphones are strongly encouraged. Groups wishing to attend are welcome to do so -- the tickets are per-connection to the meeting space, not per-person.

Subscribers to the CommonsWare Warescription have access to a discount code for this event -- if you are a subscriber, visit your Warescription page for details. However, discount codes are only available for the first 8 attendees per time slot.

Registrants will be emailed instructions, including instructions for logging into the meeting space, ~24 hours before the webinar.

Note that if fewer than three people sign up for the webinar for your chosen time slot, the webinar will be cancelled. You will get a full refund of your purchase.
