Android Question Job1.Download2 -> sending message to waiting queue of uninitialized activity (submitjob)

[KMatle]

Hi guys,

I got stuck with this little problem (there are some similar threads but nothing helped).

Using B4A 3.80

Dim Job1 As HttpJob
    Job1.Initialize("CheckDevice", Me)
    Job1.Download2("http://www.xxxx.yyy/register/register.php", _
      Array As String("Action", "CheckRegister", "Imei", imei, "Mail", RegMail.Text))

in Activity_Create(FirstTime As Boolean)

works perfect.

But when I move it to a sub the logs show "sending message to waiting queue of uninitialized activity (submitjob)" and JobDone is not called.

Of course I tried to DIM Job1 in Globals but this didn't work either.

For sure a simple thing but I need a push in the right direction.

Job1.Initialize("CheckDevice", Me)

ME is the Activity the job is called... probably your activity with the sub... Did you dim and initialize the job in your sub in an other way?

What´s the content your your sub?

 

[KMatle]

Here's the code (simplified):

This works

Sub Activity_Create(FirstTime As Boolean)
 
    Dim Job1 As HttpJob
    Job1.Initialize("CheckDevice", Me)
    Job1.Download2("http://www.xxxx.yyy/register/register.php", _
      Array As String("Action", "CheckRegister", "Imei", imei, "Mail", RegMail.Text))
 
End Sub
 
Sub JobDone (Job As HttpJob)
 
...
 
End Sub

This doesn't work for the first time (with the message above):

Sub Activity_Create(FirstTime As Boolean)
   CheckDev
End Sub
 
 
 
Sub JobDone (Job As HttpJob)
...
 
End Sub
 
Sub CheckDev
 
    Dim Job1 As HttpJob
    Job1.Initialize("CheckDevice", Me)
    Job1.Download2("http://www.xxxx.yyy/register/register.php", _
      Array As String("Action", "CheckRegister", "Imei", imei, "Mail", RegMail.Text))
 
 
 
End Sub

 

[DonManfred]

Did you call CheckDev from another Activity?

 

[KMatle]

No. For a test I made a new project with the code lines above only.

Will upload the project this evening. Must be something very stupid.

 

[KMatle]

Here's the code.

Sub Process_Globals
    'These global variables will be declared once when the application starts.
    'These variables can be accessed from all modules.

End Sub

Sub Globals
    'These global variables will be redeclared each time the activity is created.
    'These variables can only be accessed from this module.

   
   
    Private Button1 As Button
End Sub

Sub Activity_Create(FirstTime As Boolean)
    'Do not forget to load the layout file created with the visual designer. For example:
    Activity.LoadLayout("1")
    'just a button to trigger
   
   
   
End Sub

Sub Activity_Resume

End Sub

Sub Activity_Pause (UserClosed As Boolean)

End Sub
Sub JobDone(Job As HttpJob)
    ProgressDialogHide
    If Job.Success Then
        Dim res As String
        res = Job.GetString
        Log("Response from server: " & res)
        Dim parser As JSONParser
        parser.Initialize(res)
       
    Else
        ToastMessageShow("Error: " & Job.ErrorMessage, True)
    End If
    Job.Release
End Sub
Sub checkd
    Dim Job1 As HttpJob
    Job1.Initialize("CheckDevice", Me)
    Job1.Download2("http://www.b4x.com/print.php", _
      Array As String("first key", "first value :)", "second key", "value 2"))
End Sub


Sub Button1_Click
    checkd
End Sub

Log:

** Activity (main) Resume **
** Service (service1) Destroy **
** Service (service1) Create **
** Service (service1) Start **
Connected to B4A-Bridge (Wifi)
Installing file.
** Activity (main) Pause, UserClosed = false **

** Activity (main) Create, isFirst = true **
** Activity (main) Resume **
sending message to waiting queue of uninitialized activity (submitjob)
** Service (httputils2service) Create **
** Service (httputils2service) Start **
Response from server: POST variables:

}


GET variables:

array(2) {
  ["first_key"]=>
  string(14) "first value :)"
  ["second_key"]=>
  string(7) "value 2"
}
** Activity (main) Create, isFirst = false **
** Activity (main) Resume **
** Activity (main) Pause, UserClosed = false **
** Activity (main) Create, isFirst = false **
** Activity (main) Resume **

By the way: I wonder why every example about httputils(2) is placed in Activity_Create(FirstTime AsBoolean) ONLY. Is there a special reason for it?

This code (I call www.b4x.com/print.php copied from Erels httputils2 example) only works from the 2nd call. At call #1 the message above occurs and I don't have a clue.

There is a Layout with a simple button to trigger checkd.

Problem solved:

@Erel : When I test an app using httputils2 and set some breakpoints arround initializing the httpjob then the behaviour occurs (doesn't come back to job done & message is logged but works after the 1+n'th try). Seems that this kind of process doesn't want any interruption.

Without breakpoints between, it works without any problems.

 

[Erel]

I've ran Testapp in debug(rapid) mode with the breakpoints you set and wasn't able to reproduce this issue. Can you describe the exact steps?

 

[KMatle]

I used "Debug (legacy)"

1. See picture (I set breakpoints to subs: JobDone , checkd and button1_click
2. After install press the button
3. Step trough debugger with "Step to the next line F8" (I used my mouse to click it)
4. After Job1.Download2 is executed, the message "sending message to waiting queue of uninitialized activity (submitjob)" occurs.
   

 

[KMatle]

I took your php script to demnonstrate. Setting breakpoints outside of this - let's say "little time corridor between Job.Download2 and JobDone" - is ok.

 

[Erel]

Why don't you use the rapid debugger?
