Android uses Vitamio to build its own universal player (9)--online playback (online TV) _android

Objective

If you do not want to find the video, the traditional way to watch TV is also good, such as CCTV, Hunan TV and so on. This chapter collects hundreds of television stations from the network address, uses the multi-level classification method to present, greatly enriches the on-line broadcast part the content.

Series

1. Android uses Vitamio to build its own universal player (1)--ready

2, Android uses Vitamio to build its own universal player (2)--gesture control brightness, volume, zoom

3, Android use Vitamio to build their own universal player (3)--local playback (main interface, video list)

4, Android use Vitamio to build their own universal player (4)--Local playback (fast search, data storage)

5, Android use Vitamio to build their own universal player (5)--Play online (play cool video)

6. Android uses Vitamio to build its own universal player (6)--Play Online (playlist)

7, Android use Vitamio to build their own universal player (7)--Play Online (download video)

8, Android uses Vitamio to build its own universal player (8)--Detail optimization

Body

I. Objectives

To add the TV station in the online video column by the multilevel catalogue classification method.

Second, the main code

   TV's address is currently in the XML file, then the code is mainly parsing XML data.

This article is a new start MacBook Pro on the first article, a lot of not accustomed to, still in a day to successfully discard the mouse, from iOS another step closer: A series of articles does not emphasize the use of a technology, but as far as possible involves a variety of technologies, only to fully understand the various technologies in the appropriate time to use the appropriate technology. First realize after optimization, do not have to one-step entangled in every detail.

The above is on the Android Vitamio development broadcast online TV related information, follow-up continue to add.
