Android Weekly Issue #410

Dark Mode: three Lint checks to help

夜间模式的Lint检查.

Connectivity State on Android 10 and Above

网络检查的API现在更新了.

不再使用CONNECTIVITY_ACTION和NetworkInfo了, 而要用: NetworkCallback.

API 24+:

val cm = context.getSystemService(CONNECTIVITY_SERVICE) as ConnectivityManager
cm.registerDefaultNetworkCallback(ConnectivityCallback())


class ConnectivityCallback : NetworkCallback() {
    override fun onCapabilitiesChanged(network: Network, capabilities: NetworkCapabilities) {
        val connected = capabilities.hasCapability(NET_CAPABILITY_INTERNET)
        notifyConnectedState(connected)
    }
    override fun onLost(network: Network) {
        notifyConnectedState(false)
    }
}

需要提供后向兼容.
