You can use this.

((WifiManager) mContext.getSystemService(Context.WIFI_SERVICE)).getDhcpInfo().serverAddress

Full Code

private String getHotspotIPAddress() {

    int ipAddress = mContext.getSystemService(Context.WIFI_SERVICE)).getDhcpInfo().serverAddress;

    if (ByteOrder.nativeOrder().equals(ByteOrder.LITTLE_ENDIAN)) {
        ipAddress = Integer.reverseBytes(ipAddress);
    }

    byte[] ipByteArray = BigInteger.valueOf(ipAddress).toByteArray();

    String ipAddressString;
    try {
        ipAddressString = InetAddress.getByAddress(ipByteArray).getHostAddress();
    } catch (UnknownHostException ex) {
        ipAddressString = "";
    }

    return ipAddressString;

}
