Send StringBuilder Contents over a Socket

See more Socket/SSL/TLS Examples

Demonstrates Socket.SendSb, which encodes the contents of a StringBuilder using StringCharset and sends the resulting bytes.

// Important: Don't forget to include the call to System.loadLibrary
// as shown at the bottom of this code sample.
