Hi,
I start an app with a pushservice. When the message is clicked, a download starts. Everything runs fine, until ... see my comments.

B4X: 
Sub schreib
   If writing=True Then Return
   writing=True
   Label1.Text=Basis.t_saving & "x"
   ' The 3 lines above are executed. I can see label1.text

   Msgbox ("vor deletepic","")
' not executed. I see no msgbox
   Label1.Text="1"
' not executed
...

When I am in debug mode, the app is alive and I start the push notice, everything runs fine. But when the app is not allive and has to be started via the push notice, I cannot debug.

Strange ...

Right, thanks! But the debugging info does not help me, the logs I created are not there.

It seems that the app hangs at a certein point without any reason, but not in debug mode. Some timing problem?

It does not crash, it behaves beyond all logic. You won't see much here ...

The problem is - I do not know that. And it has nothing to do with the push service, I checked that.

It is a simple sub in an activity module.

B4X: 
Sub schreib
   If writing=True Then Return
   writing=True
   Label1.Text=Basis.t_saving
   ' All the follwing lines are executed in debug mode.
   ' And in release mode, I see no changes on the screen, the sub deeletepic seems to be executed, but not readphoto.

   ' Msgbox ("vor deletepic","")
   ' Label1.Text="1"


   CallSubDelayed (Me,updatescreen(1))
   
   Basis.deletepic (Main.photonumber)
   ' Msgbox ("vor readphoto","")
   ' Label1.Text="2"
   
   CallSubDelayed (Me,updatescreen(2))
   Basis.readphoto (Main.photonumber & ".dat")
   Dim s As String
   s=Main.hostname & "_downloaded.php?nr=" & Main.photonumber & "&p=" & Settings.pnr
   DoEvents
   Dim jobx As HttpJob
   jobx.Initialize ("x",Me)
   Log (s)
   ' Msgbox (s,"")
   ' Label1.Text=s
   jobx.Download (s)
   CallSubDelayed (Me,updatescreen(3))

DonManfred already explained why CallSubDelayed (Me,updatescreen(1)) does not work as expected. You should start by fixing that.

OK, the file is attached. After pressing the only button "Do it" the procedure starts.

In debug mode:

Module synch, line 179: Module show should open. But it does not.

B4X: 
      Main.script="Draw/"
      Activity.finish
      StartActivity (Show)

In release mode:

Now it crashes, I tried USB debugging but I get no log (I disconnected, the device is in USB debug mode, connection to the computer is established.

But I know it is in this sub, because this line "Basis.readphoto (Main.photonumber & ".dat")" takes quite a few seconds, so that the tex of the label ("2") should be visible.

B4X: 
Sub schreib
   If writing=True Then Return
   writing=True
   Label1.Text=Basis.t_saving
   
   ' Msgbox ("vor deletepic","")
   Label1.Text="1"


   ' CallSubDelayed (Me,updatescreen(1))
   
   Basis.deletepic (Main.photonumber)
   ' Msgbox ("vor readphoto","")
   Label1.Text="2"
   
   ' CallSubDelayed (Me,updatescreen(2))
   Basis.readphoto (Main.photonumber & ".dat")
   Dim s As String
   s=Main.hostname & "_downloaded.php?nr=" & Main.photonumber
   DoEvents
   Dim jobx As HttpJob
   jobx.Initialize ("x",Me)
   Log (s)
   ' Msgbox (s,"")
   Label1.Text=s
   jobx.Download (s)
   ' CallSubDelayed (Me,updatescreen(3))
End Sub

Someone please help me. Charge something if you want, or let me donate, whatever.

OK, now I see what you're trying to do. Schreib is in fact the sub called by unzip_UnZipDone and unzip_unzipprogression, two events raised by my Archiver lib. Contrary to Erel, I raise all my events in their thread. If you want to run these events in the main thread to perform an operation that requires to be run in this UI thread (e.g. displaying a MsgBox, updating a view, etc.), you have to call your code with CallSubDelayed. So your solution could simply be CallSubDelayed(Me, "schreib") in the two events. BTW, you should rename this function to add an underscore in its name. And stop running in Debug Mode. Different thread = Release Mode. It's not an option.

I know that, but I did not have more info.

Now I did 2 things:

1. Removed the libraries I do not need for the test. Maybe you can test now.
2. Inserted some msgboxes. It happens between here
B4X: 
Basis.debuginfo ("starting unzip",False)
ar.AsyncUnZip (Main.outdir,fname,Main.outdir,"unzip")
and here
B4X: 
Sub unzip_UnZipDone(CompletedWithoutError As Boolean, NbOfFiles As Int)
   ' Msgbox (CompletedWithoutError, NbOfFiles)
   Basis.debuginfo ("unzipdone starting schreib",False)
   CallSubDelayed (Me,schreib)
End Sub

Sub unzip_unzipprogression (count As Int, filename As String)
   Basis.debuginfo ("unzipprogression starting schreib",False)
   CallSubDelayed (Me,schreib)
End Sub
These subs are never reached. The program crashes after 1 second.

Thank you!

I have taken the callsubdelayed out long ago, because I do not need them. It has nothing to do with that.

Screenshot is of no value. "the application has been stopped".

It happens while unzipping is working. But I see your point, will try to get further info.

This is the log file. I do not know how to provide more information.

It happens between

ar.AsyncUnZip (Main.outdir,fname,Main.outdir,"unzip")

and these subs ar never reached

Sub unzip_UnZipDone(CompletedWithoutError As Boolean, NbOfFiles As Int)'
Sub unzip_unzipprogression (count As Int, filename AsString)
