I am trying to write a music player in Android, and was trying to use service to play music in infinite loop in background.

The question is, if I use service binder then the service will likely to be terminated with the activity when the activity is in the background. How to make sure the service can keep running without the activity and in activity some of the service's method can still be called? Is using foreground service with binder a solution? The service will not be killed in this way? Thanks in advance!
