Is there platform functionality missing to enable this?
I think the only platform pieces that are really missing is the ability to directly set a ringtone. Especially now that we have WebAudio landed (has it been uploaded to v1.2?) that should make some of the above even easier I think. What we might be missing is an mp3 encoding API. Is that part of WebAudio? Though I suspect you can work around that by simply grabbing chunks from the existing file, though it might be pretty painful to do so. You can work around the ability to directly set a ringtone by saving the edited song using DeviceStorage and then letting the user manually go over to the settings app and set the ringtone there. But it would definitely be better if we had a built-in app which responded to a WebActivity specifically and which allowed directly setting a ringtone. That both results in a better UX, and means that the ringtone-editing-app wouldn't need to be a privileged app. / Jonas _______________________________________________ dev-b2g mailing list [email protected] https://lists.mozilla.org/listinfo/dev-b2g
