It is always good to search the community before asking. I just searched for the word ringtone.

How do you to set a sound as a ringtone?

Hello friends! I'm a newbie at App Inventor development. I created a simple app that plays or pauses an audio file when the user clicks the play button. It also changes the button image based on the audio's status. [blocks] Please let me know how I can make it so that the user can set that audio file as a ringtone. Thank you very much for the help.
