How to Register New File Type Association with MP3 in Android Studio

While working with mp3 file in your res\raw when Run the app (Shift+F10) android studio will ask for New File Type Association. There are two ways to handle this:

First:

Check the option "Open matching files in associated application" and click OK.

Second:

You can add manually and also remove the file association (If you have previously incorrectly associated "*.mp3" with something else, then Android Studio warns you and allows you to delete the old association).

Select File -> Settings (Ctrl+Alt+S) -> File Types -> Files Opened In Associated Applications

Click on the + sign

Add "*.mp3"

Click OK.

Note:

Resource names must contain lowercase a-z, 0-9 or underscores.
