I have used B4A for several years but I have only just tried using B4J, and I am still testing things out with small sample apps. I have used B4JPackager successfully in several previous trials. Now I am trying to package an app and get an error. This is my first non-UI app, but that might not be connected.
Here is the app ...
... and here is the error ...
Can you tell me where I should be looking?
Here is the app ...
B4X:
'Non-UI application (console / server application)
#Region Project Attributes
#CommandLineArgs:
#MergeLibraries: True
#End Region
Sub Process_Globals
Dim url As String ' URL passed from caller
Dim dest As String ' Destination file from caller
End Sub
Sub AppStart (Args() As String)
If (Args.Length = 2) Then
url = Args(0)
dest = Args(1)
Else
ExitApplication ' Missing argument
End If
downloadAndSave ' Do the job
StartMessageLoop
End Sub
'Return true to allow the default exceptions handler to handle the uncaught exception.
Sub Application_Error (Error As Exception, StackTrace As String) As Boolean
Return True
End Sub
Sub downloadAndSave
Dim destDir As String ' Destination folder
Dim destFilename As String ' Destination file
dest.Replace("/", "\")
Dim p As Int = dest.LastIndexOf("\")
destDir = dest.SubString2(0, p)
destFilename = dest.SubString(p + 1)
Dim j As HttpJob
j.Initialize("", Me)
j.Download(url)
Wait For (j) JobDone(j As HttpJob)
If j.Success Then
File.WriteString(destDir, destFilename, j.GetString)
End If
j.Release
StopMessageLoop
ExitApplication... and here is the error ...
Can you tell me where I should be looking?
