Monitor internet connection in android

Create a class that notifies observe classes about the network connection and disconnection.

/**
 * Internet Util class to observer connection.
 */
class InternetConnectionUtil constructor(context: Context, listener: (Int) -> Unit) {
    init {
        val connectivityManager = context.getSystemService(CommonActivity.CONNECTIVITY_SERVICE) as ConnectivityManager
        val networkRequest = NetworkRequest.Builder().build()
        connectivityManager.registerNetworkCallback(networkRequest, object : ConnectivityManager.NetworkCallback() {
            override fun onAvailable(network: Network) {
                super.onAvailable(network)
                listener(1)
            }

            override fun onLost(network: Network) {
                super.onLost(network)
                listener(0)
            }
        })
    }

}

After that create a ViewModel which would observe the InternetConnectionUtil

class LiveVideoViewModel: ViewModel() { 
 private val _internetStateFlow = MutableStateFlow(-1)
    val internetStateFlow = _internetStateFlow.asStateFlow()
    fun monitorInternetConnection(context: Context) {
        InternetConnectionUtil(context) {
            _internetStateFlow.value = it
        }
    }
}

Then it's time to observe it either in Activity or Fragment depend on your use case

lifecycleScope.launch {
    viewModel.internetStateFlow.collect {
            if (it == 1) {
                //internet connected
                Log.d("network_connection:", "internet connect= $playerFragment")
            } else {
                //internet lost
                Log.d("network_connection:", "internet disconnect=  $playerFragment")

            }
        }
}
