Use Vitamio to create your Android universal player (9)-Online playback (online TV)

 

Preface

If you don't want to watch videos on your own, you can watch TV in the traditional way, such as CCTV and Hunan TV. This chapter collects the addresses of hundreds of TV stations on the Internet and presents them in multi-level classification mode, greatly enriching the content of online playback.

Body

I. Objectives

Add a TV station under an online video topic by using multi-level directory classification.

 

 

Ii. Main Code

The TV station address is currently in an XML file, so the code in this article is mainly to parse XML data.

This is the first article written on the new Macbook Pro. Many are not used to it. The mouse is still discarded within one day, which is a step closer to IOS. The series of articles do not emphasize certain technologies, however, multiple technologies are involved as much as possible. Only by fully understanding various technologies can appropriate technologies be used as appropriate. Optimization is implemented first, so you don't have to worry about every detail in one step.
