As many of you might know, Android has many volume streams such as:
STREAM_ALARM The audio stream for alarms
STREAM_DTMF The audio stream for DTMF Tones
STREAM_MUSIC The audio stream for music playback
STREAM_NOTIFICATION The audio stream for notifications
STREAM_RING The audio stream for the phone ring
STREAM_SYSTEM The audio stream for system sounds
STREAM_VOICE_CALL The audio stream for phone calls
I have been using content observer. I can detect change in one volume stream so far but I would like to know how to detect change in any of the aforementioned streams. I have followed the approach in this answer https://stackoverflow.com/a/15292255/2433261
Edit: Before you flag this question as duplicate, please notice that I want to detect change if any of the volume streams changes in amplitude.
