None of the (AudioManager.STREAM_*
) volumes go to 100 (int).
A valid stream volume for setStreamVolume(...)
is between 0 and getStreamMaxVolume(int streamType)
.
Each stream can have a different max volume int, like 8, 10, or 16 from what I remember. Might even be different on different devices.
I hope that is enough to point you and future visitors in the right direction.
