Android development Local and network MP3 Music Player (19) Notify Media Library to update newly downloaded MP3

Implementation features:

Notify Media Library Updates

Tangled up a few days, Baidu to a method that can be updated in Android 4.4, notify Media Library.

The Media Library is updated and the app is reopened to see the new songs, but this is still not perfect.

After the post will be implemented, the download music will be successful after you update the Media Library, update the local music list.

Because, there is no own server, so the network music all related functions (including search music, download music, download lyrics) can not guarantee the timeliness, suggestions, as soon as possible to download and practice; If you download, already because I collected the server change rule, please give me a message, if can solve, I will present a new source when I am free.

Until the current source download:
