getaddrinfo() failing in Android?

I'm building a C library we have using the Android NDK build chain. Things are working in general, but the following section is causing problems:

#include <netdb.h>
...
    struct addrinfo* addr_result;

    struct addrinfo hints;
    memset(&hints, 0, sizeof(hints));
    hints.ai_family = AF_INET;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = IPPROTO_TCP;

    LOGD("host name: %s", name);
    result = getaddrinfo(name, GCSL_NULL, &hints, &addr_result);
    LOGD("result: %d", result);

getaddrinfo is returning an error code of 7, which translates to "EAI_NODATA".

I tried forcing "name" to easy urls like "www.google.com" and "http://www.google.com" but nothing works.

I'm debugging using the emulator, which in general is able to connect to the Internet from other applications.

Insure that you have INTERNET permission in AndroidManifest.xml.

It looks like this could be caused by an emulator DNS bug:
