Network video is not http protocol is rtsp
This is a streaming media
You play your local files that are already playing
operationNetwork can not be so engaged

1. Ensure that you can open http streaming media address on a computer browser
2 There http streaming and rtsp, setDataSource url can be directly transmitted, but time-consuming preparation stage of streaming media, you can not call the start function directly after prepare, need to meidplayer registered OnPreparedListener functions. In onPrepared function to call start function.
You also have the class to write the first comment there, but did not.

mediaPlayer.setDataSource ("http://192.168.1.114:8080/webdav/china.3gp");

Here the usage right.

Should:

Uri uri = Uri.parse ("http://192.168.1.114:8080/webdav/china.3gp");
mediaPlayer.setDataSource (this, uri);
