iOS Question [RESOLVED] App Unexpected Crash, very little to go on

Jmu5667 · Oct 19, 2021

Hi

I managed to get this using iReleaselogger, I have KSCrash in the app but when the app is started again, error report count is zero.

B4X:

SignalHandler 11

)

No idea what it means but seems to be related to b4xloadingindicator. Is there any docs or resources availble to teach us how to read the trace in B4i ?

Regards

John.

Does it also happen in debug mode?

Jmu5667 · Oct 19, 2021

No, only in release. I think I may have tracked it down. In a code module I was calling a func in main with callsub2(Main,"show_busy",False), (this make the indicator visible or not), I have changed it to CallSubDelayed2(Main,"show_busy",False). The crash was very intermittent.

Do you think this could be the cause ?

Jmu5667 · Oct 19, 2021

Happened again, but did not have iReleaseLogger running. I will keep testing.

Just crashed again, and got this:

Jmu5667 said:
callsub2(Main,"show_busy",False)

Why not: Main.Show_Busy(False) ?

Try to disable the indicator and see if it happens.

Jmu5667 · Oct 20, 2021

Ok, will try it.

Jmu5667 · Oct 20, 2021

This is the latest crash information having changed the callsubdelayed to the direct call, Main.Show_Busy(False).

If the app is put do the background should the indicators be hidden ?
The next test I will not turn the indicators on at all.

I am using B4i Version: 7.80 BETA #1, iphone os version 14.8, issues was detected pres 14.8

Erel · Oct 20, 2021

When does the error happen?

SignalHandler errors are in many cases related to missing PList descriptions.

Jmu5667 · Oct 20, 2021

This is the procedure:

In the app there is a user function call TPA(Timed Personal Alert). It allow the user setup an timed alarm for doing a task. The user selects the end time, entered some notes and clicks a toolbar button to confirm their selection. A process is started to connect to a socket server and send the request. On the connection is made to the server the packet of data is sent. The app is expecting '$ok_data' to come back from the server. We are doing testing to see how the app handles a faulure in not receiving the '$ok_data'. The app will try 10 time to complete the process before giving up.

This is our log from the app for the last crash, not using the indicators at all:

I know it is alot to look at, I am now wondering has this got to do the connection to the server and the cls_tpa_sender::Initialize which called when an attempt is made to connect and send.

Regards

John.

My uneducated guess is that somewhere you have an event sub or Wait For call, with a parameter with the wrong type.

Ok, I will now check this in debug mode

Jmu5667 · Oct 20, 2021

In the cls_tpa_sender class, I discovered that I was Initializing the socket class (Dim ws_data As cls_sockets) after the socket was closed. Most of the code was taken from the Android version as alot of the code is compatable. I removed this, and have re-enabled the on screen indicators. I also put a test condition in so it will try the process for ever. I started testing @ 10:39 and iRelease logger is connected and so far no errors.

I wonder could this have beem the issue all along ?

It is safer to Dim the variable again before you call Initialize.

Ok, point taken, I will close this thread, all seems to be ok now.
