Android online video playback

During this time, I always saw online video playback materials and summarized them as follows:

1. You don't have to say anything about playing a local video, whether it's videoview, surfaceview, or mediaplayer.

2. Online playback server video:

A. You can use videoview or surfaceview to play a video in progressive download format.

B. Streaming Media videos can also be used (this is the best and most popular. It's a pity that I have read some materials and I haven't done it yet ...)

The code for implementing progressive download video playback is attached below:

I am writing the URL to death. Otherwise, you can enter the URL through edittext. The video in the URL must be in progressive download format. (You can use code to convert a video to a progressive download format. You can also use quicktime to export the video to a progressive download format)
