Now in Android a new, open source, real-world app - eher devoha: Google mit einer neuen, monströsen Vorzeigeapp.
Firstly, it showcases best practices, opinionated designs, and solutions to complex real-world problems which other sample apps don’t handle. It does so with an open source implementation of a real world app. Secondly, it helps you (the developer) keep up to date with the areas of Android development which interest you most. It is a working app planned for publication on the Play Store.
