135: You can’t learn everything

Donn’s on a roll again this week and talks to us about his experience having developed Android for a while. In the early days of Android development, as app developers we felt like we had a decent grasp of everything you needed to know to pump out decent apps.

But with the time, and the latest updates, that has become a tricky thing. This is a good problem to have for the ecosystem but it can make it seem very daunting for developers, both new and old.

Donn gives his 2 cents on this subject.
