How to load stream layer on android mobile?

Question

I've publish the stream service using arcgis geoevent server.

And I've get the stream layer result from arcgis server rest url  (http://192.168.1.107:6080/arcgis/rest/services/GeoEvent/GPSVehicles/StreamServer ).

When I copy the html and javascript from web (REST URL > view in Javascript > view source ) to mobile using cordova, the connect becomes error.

A web socket connection to the stream service running at http://myserver:port/arcgis/rest/services/GeoEvent/GPSVehicles/StreamServer could not be established.

How to develop a map running on mobile with stream layer?

Environment:

ArcGIS Server 10.4.1

ArcGIS GeoEvent 10.4.1

ArcGIS API for JavaScript 3.19 (compact)

Visual Studio 2015 (Tools for Apache Cordova)

Android API (no specify)

Furthermore, on streamLayer "connection-error" event, the error message:

Error: Failed to construct 'WebSocket': Refused to connect to 'ws://leo:6180/arcgis/ws/services/GeoEvent/GPSVehicles/StreamServer/subscribe?outSR=102100' because it violates the document's Content Security Policy.
