How to get current system volume level (Music, Alarm, Voice Calls) and set it on seekbar in your Android App?

This video shows the steps to access the volume level of different stream types of your phone and set it on seekbar in your Android App.

It also uses textview to display the volume levels in integer form.

For setting the volumes from your App, please refer to the below page:
