一、

    由於專案需求，需要早android裝置上架一個websocket服務，可以供瀏覽器呼叫。但是移動裝置的ip是不固定的，也就是說到作為服務端，移動裝置並不能完全滿足客戶端的需要。後來想到了用一臺中轉伺服器，在這臺伺服器上架上websocket服務，然而移動端和pc端都是作為websocket的客戶端存在。

二、

       如過websocket要走wss通訊，就需要載入證書。載入證書之前首先的有證書，下面是一個做自簽證書的步驟：http://blog.csdn.net/langeldep/article/details/54846720

如果以上命令列還不能滿足你製作證書，你也可以用KeyStore Explorer  這個工具製作，很方便快捷。

                                     s = ExampleServer.getIstance(address, SigninActivity.this
 
);
                                    // ExampleServer s =  new ExampleServer(address,SigninActivity.this);
