Determine network connectivity

    /**     * 判断网络是否可用, 在使用网络请求是预先使用此方法进行检查, 以节省资源.     *     * @return 可用状态     */    publicstaticbooleanisNetAvailable() {        Context context = App.getAppContext();        ConnectivityManager manager = (ConnectivityManager)             context.getSystemService(Context.CONNECTIVITY_SERVICE);        NetworkInfo info = manager.getActiveNetworkInfo();        returnnull && info.isAvailable() && info.isConnected());    }

Determine the network type

Connectivitymanager conman = (Connectivitymanager) context. Getsystemservice(Context. CONNECTIVITY_service);//3Gstate Mobile = Conman. Getnetworkinfo(0). GetState();Wifistate WiFi = Conman. Getnetworkinfo(1). GetState();if (mobile = = Networkinfo. State. CONNECTED|| Mobile = = Networkinfo. State. Connecting) {//TODO:inchMobile do something} else if (WiFi = = Networkinfo. State. CONNECTED|| WiFi = = Networkinfo. State. Connecting) {//TODO:inchWiFi Do something}
