How to use Twilio AndroidSDK behind sock proxy with Java System Property

Question

I will use Twilio AndroidSDK. i need using Twilio AndroidSDK behind socks5 proxy.

I wrote this code under ClientActivity.java in twilio-mobile-quickstart

NEW IDEA: no use ProxySelector. only Systems Property Connecting..

protected void onCreate(Bundle savedInstanceState) {
    System.setProperty("java.net.useSystemProxies","true");
    System.setProperty("proxyHost","[Proxy Server Addr]");
    System.setProperty("proxyPort","[Proxy Server Port]");
    System.setProperty("http.proxyHost","[Proxy Server Addr]");
    System.setProperty("http.proxyPort","[Proxy Server Port]");
    System.setProperty("https.proxyHost","[Proxy Server Addr]");
    System.setProperty("https.proxyPort","[Proxy Server Port]");
    System.setProperty("socketsProxyHost","[SOCKS5 Server Addr]");
    System.setProperty("socketsProxyPort","[SOCKS5 Server Port]");

I get new errors. can't connecting SSL. i feel my device connect to host directlly.

Twilio this https connection can't connect with proxies? :(

in closed network, detect this log:

Anyone might have an idea where did i do wrong? Thanks in advance.

Twilio developer evangelist here.

I'm afraid the Twilio Client Android SDK does not currently support SOCKS proxies, which is why you are seeing these issues.

I recommend you get in touch with Twilio support with your requirements and they will be able to notify you if proxy support is added to the SDK.

Let me know if that helps at all.
