I’ve been witness to some technical Android UI performance discussion between
Joaquim Vergès (developer of the recently released and awesome Falcon Pro twitter client) and Romain Guy (Google Android engineer), and by reading them I realized how often we ignore some very clear guidelines that even lint tells us (such as overdrawing issues), that impact in the framerate of our scrolling in Android apps.
After all the discussion, Romain Guy synthesized his analysis
in a post in his web. Very recommended reading for a Sunday morning IMHO.
