Maybe I'm missing something, but I don't see you describing your DNS client anywhere. Does the bionic libc do that?

Thanks Csillag,

I did tried busybox and it produces the similar error. The only difference is with busybox, I can't even ping "localhost" which is defined in /etc/hosts. Ping to IP address works fine.
Note: I am building busybox statically linked.

Do you know how does android applications resolve names or how do I get the android ping to work with name?

Thanks.

I think the thing is that android userland tools (bionic libc) does
not use resolv.conf nor nss. You should use busybox for this purpose.
