I have added plugin cordova-plugin-whitelist

added chrome extension i run this app in android device and debug i chrome browser

this is my server HTTP request call

callserver(methodname, metadata, metainfo){
    var TIMEOUT_REQUEST =10;

  var request = {
    "MetaData": metadata,
    "MetaInfo": metainfo
  };
  const httpOptions = {headers: new HttpHeaders({'Content-Type': 'application/json'})};

  return this.http.post(this.URL+methodname,request,httpOptions).pipe(
    catchError(this.handleError)
  );
  }
