I'm trying to build AOSP 7 and want to remove all volume controls expect media volume. So volume up\down control only media volume
I found that 8 has config_single_volume in framework core config.xml.
<!-- Flag indicating whether all audio streams should be mapped to
one single stream. If true, all audio streams are mapped to
STREAM_MUSIC as if it's on TV platform. -->
<bool name="config_single_volume">false</bool>
How to make it on older 7 android version?
