Static variable in Foreground Service

Issue

My question is very simple. I have a foreground service that, when activated, runs indefinitely until the user stops it. In the I MainActivity, I need to know if the service is running or not (image if the user closes the app but the foreground service is still running, when he reenters the app, I need to know if the service is already running). Is it viable to have a companion object on the Service with a status variable so that I can access its status? Something like this:

@AndroidEntryPoint
class SomeForegroundService: Service() {

    companion object {
        var status = 0
    }
....

And then somewhere in my MainActivity...

SomeForegroundService.status == 1

Is this prone to memory leaks? Whats a better solution (not counting with checking every running system service)

Solution

What you need is to bind the service

https://developer.android.com/guide/components/bound-services

If you use bindService(intent, connection, 0) without the Context.BIND_AUTO_CREATE flag, it will only bind to existing service, and return false if the service does not exist.
