I start a service from my main activity using startService(). The service checks for sockets on localhost. When it receives a socket, it reads data from it. I would like to hide the notification bar when it receives socket with specific data. I already coded a function hideNotificationBar() which is located in my main activity. The problem is I don’t know how to call this function in main activity from service.
Thanks for any help!

    Send a Broadcast from Service. Register your Activity to receive this broadcast and act upon it.

    This approach solves the problem of storing/acquiring the reference to Activity, which might become inactive during the lifetime of your Service.

    The downside is that you can only send simple types, Bundle or classes implementing Parcelable via a broadcast Intent.
