Android Question JRDC

[Trevor Parr]

Hi
I currently have an app which is a few years old now which works fine with RDC and was done with version 4.3 of B4A, I needed to upgrade it to provide more functionality so thought I would use the new JRDC2 functionality, however I'm having a few issues.. the server side is fine, I can test the connection is open and running via my browser, but the client just crashes out all the time sometime after SendJob (DbRequestManager) has been called.. and never actually connects to the JRDC server

In attempt to identify the problem I reverted back to a very simple test app.. see below.. which has the same issue.. any indicators as to the problem would be greatly appreciated (note: I have just changed the <myipaddress> rather than show actual ip)

Sub Process_Globals
   Dim reqManager As DBRequestManager
   Type DBResult (Tag As Object, Columns As Map, Rows As List)
   Type DBCommand (Name As String, Parameters() As Object)
End Sub

Sub Activity_Create(FirstTime As Boolean)
    If FirstTime Then
        'reqManager.Initialize(Me, "http://192.168.0.100:1")
        reqManager.Initialize(Me, "http://<myIPAddress>:3013/rdc")       
    End If
End Sub

Sub Activity_Click
    GetAnimal("1")
End Sub

Sub GetAnimal(Name As String)
    Dim cmd As DBCommand
    cmd.Initialize
    cmd.Name = "select_animal"
    cmd.Parameters = Array As Object(Name)
    reqManager.ExecuteQuery(cmd, 0, Null)
End Sub

Sub JobDone(Job As HttpJob)
   If Job.Success = False Then
     Log("Error: " & Job.ErrorMessage)
   Else
     If Job.JobName = "DBRequest" Then
       reqManager.HandleJobAsync(Job, "ReqManager")
     End If
   End If
   Job.Release
End Sub

Sub ReqManager_Result(result As DBResult)
   'work with result
End Sub

these are the libraries used:

Can you post the error message?

Hi Erel

No error really given it just crashes, the tablet is running Andriod 5.1, funnily enough I get the error, then around 10 seconds later I get the same error..

Apologies forgot to attach the following error in the log, is this related to an outdated core library?

Yes.

You will need to use HttpUtils2 source code instead of the compiled library. I recommend you to upgrade to the latest version of B4A.
