Volume Control Not Working in my App

Question

I'm developing a game and when the game is playing the volume control is not working. Can anyone give me the solution?

It is in AndEngine

Answer 1

I found the solution. Where the keycodes are handled return false and volume will start working. I was handling back button and returning true in all cases there. So what I did was that I returned true only when keypressed is back else return false and my problem solved.
