Android pulls in a number of external Open Source projects - and sometimes tends to stick with an outdated version even when newer versions have significant advantages.
Some projects have since been abandoned upstream.
This session will explore what projects need updating, why some projects were kept at old versions (e.g. there may have been license changes), what projects may even need replacing, and how much of that we can do without breaking compatibility too badly.
