Hello 2012 and, I have a pretty broad question. What music and ringtone types does Android support to play without adding extra apps out there? I have a hobby music site and clients can download mp3, amr, m4a, aac files for free. I intend to add an ogg library too, so that developers can add ogg files to their livewallpapers etc. http://www.smokingkitty.com So, which is best for Android clients in the broad spectrum when they visit my hobby music site, if per say they want to either download a full song and/or a ringtone? Also what are the specific html attributes to add for Android for the downloads to go smoothly?
