watchface crash - need help

You have to interpolate between the lines. Find the address in the debug.xml file which is closest to but not higher than the line number listed in the CIQ log.  The error is in that line.

Thank you for replying, truly appreciated. I think I've done exactly what you sugessted.

the PC address 0x10002660 converts to 268445280 and when looking at the debug.xml file, the closest line I can find is line190 in the onUpdate function in my view class (on address 268445257). 

On that line I make the call to the parent onUpdate: View.onUpdate() and after that call my onUpdate function exits. 

The next address in my debug.xml (268445282) sits with the Rez.mcgen file on line  42. "parent=globals/Rez/Layouts". 

This is line 41-44 in the rez.mcgen file:

(line 41) module Layouts {
(line 42)        function WatchFace(dc as Graphics.Dc) as Array<WatchUi.Drawable> {
(line 43)            var local_Rez_Fonts_DexArial64 = (WatchUi.loadResource($.Rez.Fonts.DexArial64) as Graphics.FontReference);
(line 44)            var rez_cmp_local_custom_drawable_69553608316995649298 = new Background();

First, I am not very familiar with mcgen files, I believe they are compiler generated (?) and this particular section seems to have something to do with my custom drawable and custom font.

The app runs fine in the simulator but not on the target. 

The CIQ_LOG file also has this: Details: "Could not find symbol '00800a91'"

is this information usable in any way? 00800a91 converts to 8391313 but didn't find anything in the debug.xml on that address. 

If you try to search for 00800a91 and 8391313 in all the files created during the compilation then I think you'll be able to find out what that symbol is supposed to be. (Though if it's not found then maybe you won't find it???)

Anyway, I suppose you tested it in the simulator, and there everything works as expected?

I built a side-load to one of the users having this issue and got some more details in the crash log file:

    Line: 190
    Function: onUpdate

It refers to line 190 in the onUpdate function in my view class. Line 190 looks like this:

View.onUpdate(dc);

It's the call to the parent onUpdate()

I am using relative layouts with text-areas to tailor the UX for different screens sizes. 

The crash log reveals some problem related to "Toybox_WatchUi_TextArea_>>fitTextToArea>" I am not sure what he problem is. The watch face loads fine in the preview mode and looks like it should,but when the use applies the watch face it crashes. Not able to reproduce the problem in sim, and I don't think every Fenix 5X user have this problem (but not sure). I know that text areas only works for CIQ > 3.1 but that should not be a problem with the Fenix 5. 

Could it be a bug with text-areas? 

Where is fitTextToArea in your code? I don't see anything like that in TextArea or Drawable in the docs.

Hi, I don't have that anywhere in my code. 

we can't help if you don't post your relevant code. If you think it's called from onUpdate, then show us your onUpdate, preferrably with some comment to show line 190

BTW I found this: developer.garmin.com/.../Graphics.html

Hi, line 190 in my onUpdate function is a call to the parent onUpdate. 

Are you drawing using dc calls or using layouts? If you're drawing on dc then you don't need to call parent onUpdate
