Hi! This block of code has inappropriate blocking method call warning. Does anyone know why?

CoroutineScope(<http://Dispatchers.IO|Dispatchers.IO>).launch {
    try {
        network.socketFactory.createSocket().use {
            it.connect(InetSocketAddress("8.8.8.8",53),1500)
            validNetworks.add(network)
            checkNetwork()
        }
    }
    catch (e:Exception){
        Timber.e(e)
    }
}

Why you use block use ? Did you need close the socket after end of checkNetwork() ?

[Tin Tran]

Yes I want to close it

Each of the method inside the launch should be cancellable so that once the coroutine is canceled, the execution will be canceled gracefully. Please check your use of the socket and see if any part of it is not cancellable.

I changed to use suspendable methods instead. Thanks
