Android Question HttpJob JobDone problem

[giada]

Hi,
i have an app that use HttpJob and Wait For (j) jobDone(j As HttpJob) for different kind of request.
All works correctly but yesterday the app (running on different tablet but only one had the problem) on a request not had JobDone event so all other successive httpjob request was blocked.

I think to have correctly implemented the code, how can i solve this problem? Is not a frequent event so is not simply replicable but it's appen...

I post significant part of my code:

Sub UpdateConfig
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"ESTRAGGO CONFIG OLD")
    wait for ([B]InitFileConfigOld[/B]) complete (result As Boolean)
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"FINITO")
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"ESTRAGGO PAZIENTI")
    wait for ([B]EstraiPazienti[/B]) complete (result As Boolean)
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"FINITO")
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"ESTRAGGO SOGLIE")
    wait for ([B]ChiediSoglie[/B]) complete (result As Boolean)
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"FINITO")           
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"ESTRAGGO APPUNTAMENTI")
    wait for ([B]ChiediAppuntamenti[/B]) complete (result As Boolean)
    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"FINITO")
End Sub

And each of bold sub is similar:

Sub InitFileConfigOld As ResumableSub
    Dim j As HttpJob
    Dim jg As JSONGenerator
    Dim m As Map
    Dim stringConfig As String = ""
    Dim NowFix As Long
    Dim s As String
    Dim Intent1 As Intent
    Dim sie As String
    
    If MyId <> "" Then
        NowFix = DateTime.Now/1000
        s = NowFix
        Intent1.Initialize("android.intent.action.SEND","")
        Intent1.PutExtra("cmd","deviceID")
        Intent1.putExtra("signPls", s)
        Intent1.SetPackage(Package)
        Intent1.SetType("text/plain")
        'Log(Intent1)
        StartActivityForResult(Intent1)
        Wait For ion_Event (MethodName As String, Args() As Object)
        If -1 = Args(0) Then 'resultCode = RESULT_OK
            Dim k As Intent = Args(1)
            MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"extra: " & k.ExtrasToString)
            If k.HasExtra("senderid_enc") Then
                sie = k.Getextra("senderid_enc")
                'Log(sie)
                m.Initialize
                m.Put("device_id",MyId)
                m.Put("epoch",NowFix)
                m.Put("senderid_enc",sie)
                jg.Initialize(m)
                stringConfig = jg.ToString
                'Log(stringConfig)
                j.Initialize("",Me)

    Else
        MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"id non presente")
        Return False
    End If
End Sub

In the log i see at a certain time :

04/10/21 18:23:55_196 ESTRAGGO CONFIG OLD
04/10/21 18:23:55_461 extra: Bundle[{senderid_enc=YCafpX......
04/10/21 18:23:55_482 SAVER APPEAR
04/10/21 18:24:16_629 OXY stop-start scan
04/10/21 18:24:18_517 PRESS stop-start scan
04/10/21 18:24:18_730 TEMP stop-start scan
04/10/21 18:24:46_846 OXY stop-start scan

But after there isn't the log for j.succes or j.error (all the other time there is and the ion_event is correct)

After 15minutes the sub UpdateConfig restart (called from a timer) but in the log there isn't the print ESTRAGGO CONFIG OLD as if the resumable sub UpdateConfig doesn't start!!!!!!

Suggestions? Thanks

Before this event i see error for a restart of the server (correctly managed with j.error inside JobDone event) ...
only one app have this problem, othes istances of the app correctly work also after the server restart...

Do you need to run the requests sequentially - one by one? If not then simply remove the Wait For lines in UpdateConfig.

 

[giada]

i need to do it sequentially but the problem is that no JobDone event cause all HttpJob in the app not working

 

[Erel]

JobDone should always be raised eventually. You can make the timeout shorter with Job.GetRequest.Timeout = 5000

 

[giada]

The problem is in this case is exactly that the JobDone there isn't also after many times...and this blocked everythings!

 

[Erel]

You need to debug it. First step is to add:

Log("Before wait for: " & ServerRiferimento & "/tablet_get_cfg")
Wait For (j) jobDone(j As HttpJob)
Log("After wait for: " & j)

I have 3 print in the code :

MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"extra: " & k.ExtrasToString)
......
Wait For (j) jobDone(j As HttpJob)
                If j.Success Then
                    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"SUCCESS " & j.GetString)
                    ....
                    
                Else
                    MyLog(Main.LIVELLO_DEBUG_MAIN_PAGE,"http get error : " & j.ErrorMessage)
                    ...

but no print in the log
