java - Cant stop playing sound in other Activity with MediaPlayer in Android

Question

I'm trying to play a background sound in my Android application. I'm using a seperate class as a Soundmanager. And in my first activity, i start the sound and i want it to play through 2 other activitys. And in my third class i want it to stop and another sound should play. But im having a problem stopping that sound and don't know why. I guess it has something to do with that im using the class Context in my Soundmanager class.

Does anyone know how to make the sound stop? I'll link my Soundmanager class becuase that is the only one that is relevant i guess. Im pretty new to programming, so please be gentle.

Answer 1

Make all of your methods and class variables in SoundManager static (and pass in a Context for the methods that require one).

I would suspect that you are maybe creating a new instance of SoundManager in each of your Activities, which would create multiple instances of SoundManager. Making it statically accessible will mean all Activities are modifying the same variables.

Another note, I don't think you have to have an Activity Context, so try passing in your application's Context via context.getApplicationContext(). This will avoid tying the MediaPlayer object to any specific Activity.
