have you tried not using APK’s to do the volume change? I mean, arraytype 100 supports
com.android.settings.settings$SoundSettingsActivity and possibly volume setting as well. I haven’t thought about this, but it would streamline your watchface a lot!
tested com.android.settings.settings$SoundSettingsActivity and it takes you right into the volume sliders, very handy but not what you were looking for.
Are you using audiomanager.adjust.raise/lower for the volume call on the apk?
