After the continuation is complete, the switch remains connected until the party that detects the communication hangs up. The part of the conversation is to use

A good user experience is a predictable one. if your app plays media it's important that your users can control the volume of your app using the hardware or software volume controls of their device, bluetooth headset, or headphones. Similarly, where appropriate and available, the play, stop, pause, skip, and previous media playback keys shocould perform their respective actions on the audio stream used by your app. Identify Which Audio Stream to UseThe first step to creating a predictable audio
