Tarmoq ulanishining mavjudligini qanday aniqlash mumkin?

Androidda tarmoq ulanishining mavjudligini aniqlash uchun odatda ConnectivityManager sinfi ishlatiladi. Bu yordamida faol tarmoq ulanishi bor yoki yo'qligi va uning turi (Wi-Fi, mobil ma'lumotlar va boshqalar) tekshiriladi.

Tarmoq mavjudligini tekshirish misoli:

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetwork = cm.getActiveNetworkInfo();
boolean isConnected = activeNetwork != null && activeNetwork.isConnectedOrConnecting();

Android API 29 dan boshlab, NetworkCapabilities dan foydalanish tavsiya etiladi:

ConnectivityManager cm = (ConnectivityManager) context.getSystemService(Context.CONNECTIVITY_SERVICE);
Network network = cm.getActiveNetwork();
NetworkCapabilities capabilities = cm.getNetworkCapabilities(network);
boolean hasInternet = capabilities != null && capabilities.hasCapability(NetworkCapabilities.NET_CAPABILITY_INTERNET);
