networking - Android InetAddress.getByName(ip).isReachable(timeout) always returns false -

-

i see 24 similar questions asking inetaddress.isreachable() instance never returns true, when network otherwise reachable, 1 exception of tests against 127.0.0.1.

if (inetaddress.getbyname("google.com").isreachable(2000)) {     system.out.println("visible"); } else {     system.out.println("not visible"); }

and permissions

<uses-permission android:name="android.permission.internet" /> <uses-permission android:name="android.permission.access_network_state"/>

this code started within thread (of course). app needs know if specific ip accessible (not google, in above example). behaves same in emulator.

is there better way test network connectivity?
