除非他们连接了Wi-Fi,否则我不希望我的用户甚至尝试下载某些内容.但是,我似乎只能判断是否启用了Wi-Fi,但他们仍然可以拥有3G连接.
android.net.wifi.WifiManager m = (WifiManager) getSystemService(WIFI_SERVICE);
android.net.wifi.SupplicantState s = m.getConnectionInfo().getSupplicantState();
NetworkInfo.DetailedState state = WifiInfo.getDetailedStateOf(s);
if (state != NetworkInfo.DetailedState.CONNECTED) {
return false;
}
然而,国家不是我所期望的.即使连接了Wi-Fi,我也会OBTAINING_IPADDR成为状态.
