Thanks for your help. The new version shows the canvas/sprites now, and adding the dead ladybug didn’t break it. Good progress. However, I also noticed that, while the canvas and sprites appeared at that point, it still displayed old images (in particular, with the frog facing to the left instead of the right), even though the sprites were correct in the app and in Preview on the web. It did work when I download the .apk file, so I figured something must be wrong with Live, or something was cached on my phone.
I tried exiting the Live app using the Android “back” button, backing out with the the Live app’s Back button, restarting Live Test on the website, ending and restarting the app with Android - all with no luck. I finally ended up uninstalling and re-installing Live, and that mostly made things better.
However, it still exhibits several intermittent problems. For example, the Live app will crash periodically (see attached image with error details from the last crash), the Ladybug sprite will either freeze in place or slowly migrate down the screen on its own without responding to the phone’s tilting, the slider that’s on a timer will stop moving, the debug label will stop updating (even though the frog keeps moving), the app will show a collision between the frog and ladybug even when they’re halfway across the screen from one another.
All in all, it’s a pretty frustrating experience.
Here’s a link to the latest version of the app (which is your version with the dead ladybug added, and a few minor code changes):
