I am working on an app that, among other things, provides alarms in emergencies. I would like to add a setting that will allow users to receive alarms with sound even if their phone is muted. As far as I am aware, this could be hacked by playing an mp3 through media services, as if the app was a music player left to play in the background, but that doesn't seem extremely kosher.
Does anyone know a 'neater' way to do this? Can I somehow allow my users to prioritise my app over the mute button?
Thank you very much.
