Implement DNS pre-fetcher/resolver using InetAddress or Runtime.getRuntime().exec() in ANDROID

The HTTP connection to a hostname for the first time takes little longer than subsequent requests. Especially, DNS lookup takes long.

I am trying to implement a basic DNS pre-fetcher/resolver using InetAddress or Runtime.getRuntime().exec() in order to improve the HTTP requests performance in ANDROID java without using any third-party library.

Thank you, Niz

Try this. It just determines the ip address of the host from its hostname supplied via String param. Hope it helps you.

public boolean webSiteAvailable(String url) {
try {
    InetAddress ipAddr = InetAddress.getByName(url);
    if (ipAddr.equals("")) {
        return false;
    } else {
        return true;
    }
} catch (UnknownHostException e) {
    e.printStackTrace();
    return false;
}
}
