Below line gives error as below as        device.getInternetConnection() return enum not String.            
callableStatement.setString("InternetConnection", device.getInternetConnection());


Multiple markers at this line
      - The method getInternetConnection() is undefined for the type Device
      - The method setString(String, String) in the type CallableStatement is not applicable for the arguments (String,
       Device.getInternetConnection)


Here  device.getInternetConnection()); returns the enum  InternetConnection

      public enum InternetConnection{
            
            WIFI("08"),
            CELLULAR("06");
            
            InternetConnection(String ip){
                  this.ip = ip;
            }
            
            private final String ip;
            
            public static InternetConnection getFromIP(String ip) {
                  for(InternetConnection pc : InternetConnection.values()) {
                  if(pc.getIP().equals(ip))...
                       ......
                  }
                  throw new IllegalArgumentException("This iP: " + iP + " does not exist");
            }
            
            public String getIP() {
                  return ip;
            }
      }

How to change my callable statement setter to accommodate enum instead of string?
please advise

I need to download a sharepoint file to Android.  I know how to easily download files to android from repositories which does not need any kind of authentication.

But Sharepoint being an authenticated system, I need to understand how I can achieve this programmatically.

I know about jshare which is a paid solution. I do not want to go for a paid solution. But I would like to have a free program solution for this.

Any help is much appreciated.
