Android Question How to know which list is the problem [SOLVED]

[AHilberink]

Hi,

Using crashlitics I got the following message:

{"Version":"3.94dg","Error":"java.lang.RuntimeException: Object should first be initialized (List).","Stack":"java.lang.RuntimeException: Object should first be initialized (List).........

What is the easiest way to investigate which list is causing this? I see the name of the sub, but I need to know the list name to check why this happens.

Kind regards,
André

You don't get the error when you develop? It's only something that your users experience?

Look at the sull stacktrace in the crashlytics console. There must be more infos, codefile, linenumbers ect. than just this oneliner

This not always happening and not during my development and tests. It has something to do with specific use and I need to know when it happens. That way I can check during development connected to my device.

I just paste the first line, but this is the whole message:

The key lines are:
at ciris.chauffeur.opdrachten._doen(opdrachten.java:1597)
at ciris.chauffeur.opdrachten._btndoen_click(opdrachten.java:860)
They are you original subs.

The relative java file is ciris.chauffeur.opdrachten
In Object/src/ciris/chauffeur/opdrachten.java go to the line number (actual line number in editor).
Just prior to that are comment lines that represent the B4A source file.

Look for calls to doen and btndoen.

(make sure to look at the files that were used to release the version where the error was found)

 

[DonManfred]

check opdrachten.java at lin 1597
it should give you an further idea.

Otherwise you need to debug more. add a check for the list being initialized, ect.

 

[Sandman]

And what is the code in the sub mentioned in the message?

was the part I was looking for.

Using this I can look on which part of my code needs attention.

 

[AHilberink]

check opdrachten.java at line 1597

I found the part. I do a this:

            Huidigen.Initialize
            Huidigen=DBUtils.ExecuteList(Main.SQL1,"SELECT Huidige FROM "&Main.DBAanvulling&" WHERE OpdrachtID="&OpdrachtID,Null,0)
            For i=0 To Huidigen.Size - 1

It seems on DBUtils.ExecuteList the Initialize will be gone after no result or something. I think the Huidigen.Size does the crash because of this. I will do more testing.

Thanks all for helping me out.
