Hello,
I have an application working for a few years ago that connects with a server using JSON-Rest web services, it is still not using the ResumableSub method of downloading resources, until now I had a huge JobDone Sub where I have a Select -Case statement filtered by Job.JobName in order to get the correct event in each case.
But now I am rewriting the code using Resumable Subs(I have more than 40 web methods to rewrite) and I´m getting a problem in the HttpJob module, at the begining all was working fine, I use the wait for statement and every web request have its own sub and returns its data in the right way, but I have started to get an error in the HttpJon module:
The problem is in this line of the HttpJob module:
tr.Initialize2(File.OpenInput(HttpUtils2Service.TempFolder, taskId), Encoding)
It seems that there is a problem with the temporal file.
An example of one of the subs that download data from the server:
And I use the sub in this way:
What could be the problem?

It seems that there is a problem with the temporal file.
An example of one of the subs that download data from the server:
B4X:
Sub GetGarbages(garbages As List) As ResumableSub
Dim job1 As HttpJob
Dim list1 As List
Dim p As JSONParser
Dim ret As Boolean
'Send a GET request
garbages.Initialize
list1.Initialize
job1.Initialize("GetGarbages", Me)
job1.Username=User
job1.Password=Password
job1.Download(UrlGetGarbages)
Log(job1.GetString)
Wait For (job1) JobDone (job1 As HttpJob)
If job1.Success Then
If job1.GetString.StartsWith("[") Then
p.Initialize(job1.GetString)
Else
If job1.GetString.IndexOf("[") > -1 Then
p.Initialize(job1.GetString.SubString(job1.GetString.IndexOf("[")))
Else
p.Initialize(job1.GetString)
End If
End If
'Error android 2.3
list1 = p.NextArray
Dim map1 As Map
For n=0 To (list1.Size-1)
map1 = list1.Get(n)
Log(map1)
Dim garbage As CGarbage
garbage.Initialize
garbage.garbage=map1.Get("Garbage")
garbage.GarbageId=map1.Get("GarbageId")
garbages.Add(garbage)
Next
Else
Try
Log("Error GetGarbages: " & job1.ErrorMessage)
Logger.SaveMessage("GetGarbages Error",job1.ErrorMessage)
Catch
ToastMessageShow("Error GetGarbages: " & job1.JobName, True)
End Try
End If
ret=job1.Success
job1.Release
Return ret
End SubAnd I use the sub in this way:
B4X:
Dim garbagesList As List
garbagesList.Initialize
wait for (servGet.GetGarbages(garbagesList)) Complete (Result As Boolean)
If Result=True Then
AppDBUtils.SaveGarbages(AppDBUtils.GetSQLInstance,garbagesList)
End IfWhat could be the problem?
that was the only Sub where I do that, the problem was that I was using the old code as a pattern and I didn´t realiza of that line.
