WebSocket with Android and ionic2

Dear Guys,
(new to ionic…)

I try to get WebSocket work in an ionic2 Android app.
In browser mode it is working fine.

I installed https://github.com/knowledgecode/WebSocket-for-Android and followed all the instructions:

  • installed cordova-plugin-whitelist
  • set a Content-Security-Policy (CSP)
  • set config.xml:
    < access origin=""/>
    < allow-intent href="ws://
    /:"/>
    < allow-intent href=“wss:///:*”/>

but there is no connection to my server when i test with ionic run android

connect(){
this.ws = new WebSocket(“ws://192.168.178.170:8000”);

this.ws.onopen = () => {
  console.log('open');
};

this.ws.onmessage = (event) => {
  console.log('new message: ' + event.data);
  this.messages.push(event.data);
};

this.ws.onerror = () => {
  console.log('error occurred!');
};

this.ws.onclose = (event) => {
  console.log('close code=' + event.code);
  this.connect();
};

Did i missed something?

Did you find any fix?
