1. sample projects provided by the android team

5. Standup Timer
The Standup timer application is used to control the standing meeting time, similar to the stopwatch countdown. It can remind everyone that the speech time has reached, so that each participant can use the same time. From the code of this project, you can learn how to use time functions. In addition, the code of this project is the design idea of strictly separating view and model.
