First App Frustrations

CNEMCSE 7 days ago

I'm having some trouble with my first app and I wonder if anyone has any advise. I've been working on this for a few weeks now, and everything is working beautifully in the simulator. I finally uploaded it to my Descent Mk2i and the app is crashing when I select one option from the initial menu view, and behaving strangely in another mode (the app is a navigation utility utilizing MapTrackView. when I launch the map view, I check for a current location and pop open a 'waiting for gps' view until GPS stabilizes. it should popview back to the map view, but instead it pops 2 views back to the main menu)

for the app crash, I found the CIQ_LOG.YAML file in /Garmin/Apps/Logs on the device, but it seems pretty useless. it;s not returning any stack information at all

Error: Unexpected Type Error
Time: 2024-11-17T18:07:24Z
Part-Number: 006-B3258-00
Firmware-Version: '26.10'
Language-Code: eng
ConnectIQ-Version: 5.0.1
Filename: GuideMe
Appname: GuideMe Navigator
Stack:

I also don't understand the ConnectIQ-Version. I'm using SDK 7.3.0, not 5.0.1 and the watch itself is running 3.3.0

Anyone have any suggestions for how to get better debugging info? (System.println doesn't seem to be available on the device logs)

Is there anything after stack, like pc values? Those can be translated and will point you to the code. If you installed from the app store, you'll see that in the ERA reports.

nope, nothing at all after Stack:

I side loaded it via USB cable though, I don't have my account set up to upload to the app store yet. do I need to install it from the app store to get debug info?

ERA basically just translates th pc values for you giving you a "friendly" stack trace

I'm only guessing, but are you null checking things you need to null check?

When you use "Build for Device" in the VSC command palette, make sure you specify a debug build. You'll see the "friendly" stack trace (if there is one) right on the device.

One way to test Connect IQ apps is to include System.println() statements at strategic points in your app. Within Visual Studio Code, these println() statements will output to the console. On a device, println() statements write to an <APPNAME>.TXT file in the /GARMIN/APPS/LOGS directory in the device file system.

These log files are not automatically created, so they must be manually created on the device and named to match the name of the app’s corresponding PRG file. For example, to log output from /GARMIN/APPS/MYAPP.PRG, you must create /GARMIN/APPS/LOGS/MYAPP.TXT.

Note that if you upload an app to the store, the PRG will be renamed to an unpredictable string of letters and numbers. In this case, you can find the mapping from your app to its filename by looking at garmindevice.xml. (It's not beautified, so you'll have to format it to make it human-readable. e.g. In VS Code: CTRL-SHIFT-P / CMD-SHIFT-P > Format Document.)

That's strange. I would expect the version in the log to reflect the CIQ version on your watch. You could try posting a bug report about this, and see if the Connect IQ team has an explanation for you.

VERY helpful, thank you!

I'm not 100% sure I know how to generate a 'debug' build. I used 'Start Debugging' option from the visual code Run menu, but I'm still not getting a stack trace, and just getting the IQ! crash logo on the device

When you do a "Build for device" from the VSC command palette, you are given the option to build a release build or a debug build. This only works with sideloads. If you installed from the store, look at your ERA reports.
