private static byte[] convert2Bytes(int hostAddress) {
    byte[] addressBytes = { (byte)(0xff & hostAddress),
            (byte)(0xff & (hostAddress >> 8)),
            (byte)(0xff & (hostAddress >> 16)),
            (byte)(0xff & (hostAddress >> 24)) };
    return addressBytes;
}

public static String getApIpAddr(Context context) {
    WifiManager wifiManager = (WifiManager) context.getSystemService(Context.WIFI_SERVICE);
    DhcpInfo dhcpInfo = wifiManager.getDhcpInfo();
    byte[] ipAddress = convert2Bytes(dhcpInfo.serverAddress);
    try {
        String apIpAddr = InetAddress.getByAddress(ipAddress).getHostAddress();
        return apIpAddr;
    } catch (UnknownHostException e) {
        e.printStackTrace();
    }
    return null;
