Why won't this icon draw on my watch face? - solved (kind of)

googjf 2 days ago

Been trying for 3 hours to put a bluetooth icon on my watch face (at this point I don't even care if it's actually connected to my phone or not).

Why doesn't this work:

dc.drawBitmap(20, 10, bluetooth24px); ?

I downloaded a 24 pixel bluetooth icon from the internet (as a .png file). I put it in Resources>Drawables.

I'm pretty sure I've coded most of it correctly because in the drawables.xml file, if I substitute the launcher.svg icon for my bluetooth.png icon then that draws on the screen just fine. I have tried everything I can think of but I'm out of ideas. I have tried changing background colours just in case it was trying to print black on black.

Is a 24 pixel .png too small to see? Is .png the wrong format? It's a Fenix 6X Pro, using the simulator in Visual Studio Code

Thank you for any insights anybody might be able to provide.

I will leave this here in case any other rookies like me are looking for information in the future. I have no idea why it wouldn't work, but I just downloaded a different icon from the internet and now it works.

To ensure your icon displays well across devices with different resolutions, consider using a vector graphic (SVG) instead of a PNG. In the resource definition, you can specify scaleX or scaleY as a percentage of the screen size to maintain consistent sizing.

In your source code, you can continue to use the bitmap resource as usual - no changes are needed. The compiler will automatically generate appropriately sized bitmaps for each supported device.

Another option is to use BmFont to create a custom font with the icons you want that can easily be sized for devices in the same way other custom fonts can be sized. Here's a thread with a TTF file with icons that works with bmfont: https://forums.garmin.com/developer/connect-iq/f/discussion/6777/where-to-find-standard-garmin-icons-for-use-in-apps-watchfaces
