watchface crash - need help

Hi, I have a few users (on Fenix 5x) having problems to apply my watch face. It downloads onto the device okey and it shows up as a preview as it should, when they go into watch face settings, but when the users selects "apply" to aply the watch face, it crashes and the watch loads the previous/default watch face. I have not been able to reproduce on Fenix5 or Fenix 5X Plus (I dont have a Fenix 5x).

I have received the CIQ_LOG file from one of the users and it has the following:

Error: Symbol Not Found Error
Details: "Could not find symbol '00800a91'"
Time: 2024-02-03T03:51:27Z
Part-Number: 006-B2604-00

  - pc: 0x300015aa
  - pc: 0x10002660

Only the last PC address (0x10002660) points to my source code when I lookup in the debug.xml file, none of the others do (is that normal?).

0x10002660 translates to 268445280. The closest I can find in the debug.xml file is this:

It seems to point somehwere after line 190 in my DexFaceView file (it is the very last part of the onUpdate function) and before line 43 in the Rez.mcgen file (no clue what that file is doing?).

My code looks like this:

DexFaceView.mc:

Rez.mcgen

My watch face uses layouts, with custom drawables and a custom font. I have not had any issues with it except with these two users. I am afraid I am way out of my waters here, so any help or hints with debugging this is greatly appreciated. TIA

hi, I am using layouts. Relative layouts with text-areas, to adopt the UIs to various screen sizes.

Solved it by removing text-areas from my layouts for the Fenix 5x and replaced with labels. It seems Fenix 5x does not properly handle text-areas (that includes multiple fonts), which it should since it supports API 3.1.0. Text areas require API level 3.1.0 according to https://developer.garmin.com/connect-iq/api-docs/Toybox/WatchUi/TextArea.html

Text areas work fine to compile and runs fine in the sim but crashes on target when the user applies the watch face.

This layout makes the watch face crash on target (fenix 5x):

<text-area id="TimeLabel" x="center" y="55%" width="100%" height="30%" justification="Graphics.TEXT_JUSTIFY_CENTER | Graphics.TEXT_JUSTIFY_VCENTER" color="Graphics.COLOR_WHITE">
        <fonts>
            <font>Graphics.FONT_NUMBER_HOT</font>
            <font>Graphics.FONT_NUMBER_MEDIUM</font>
            <font>Graphics.FONT_NUMBER_MILD</font>
        </fonts>
    </text-area>

And this one works:

 <label id="TimeLabel" x="50%" y="65%"  font="Graphics.FONT_NUMBER_MEDIUM" justification="Graphics.TEXT_JUSTIFY_CENTER" color="Graphics.COLOR_WHITE" background="Graphics.COLOR_TRANSPARENT"/>

nothing else was changed

We have the same problem with fenix 5x / tactix charlie users. Did you get any news on that?

Fsallstrom over 1 year ago in reply to 4806789

No. I did not get anywhere with it. When I tried register a bug report I got back that the problem is probably in my code. I dont believe there is a problem in my code, instead I think that some devices that should be able to support text areas based on their CIQ level actually don’t. I’ve seen it with some fenix devices and edge devices. If you have experienced the same problem you should go in and file a bug report and I’ll endorse it.

This one is helpful:

Not sure yet, that it fully fixes the problem, but worth a try.
