One of the hardest things about with Android is working with images.
In their uncompressed form, they take up vast quantities of memory. Even the best-written apps routinely suffer crashes and slowdowns due to the demands of images and animations.
This talk will show you how Facebook cut its image load time by two thirds, while reducing crashes and improving scroll speed. It will also cover how you can use these same techniques with the new open-source library, Fresco (http://frescolib.org)
I will cover some poorly documented features in the Android SDK and NDK that Fresco takes advantage of, including some Android source code walkthroughs.
