Mediaplayer's method of obtaining the total duration of audio and video files

1. Local file

Query the Duration field of the database audio or video view.

This method is effective for local files stored on mobile phones, but does not work for online files on the network.

2. Online files

For online files, the total duration can be obtained through the getduration method of mediaplayer after the mediaplayer prepareasync receives onprepared.

You can use the preceding method to obtain the total duration of a local ape music file after prepare is completed. Although the ape file will be scanned into the database, sometimes the scanning duration is incorrect, this method can be used for correction.

Of course, correcting a media scan error is the best way to solve the incorrect ape file duration scan.
