I'm using png bitmaps with transparency for my watchface supporting 20+ amoled watches.
Works fine on all devices except FR165/Venu Sq 2 for which the simulator fails at drawBitmap2 call, with message:
Error: Unhandled Exception
Exception: Source must be native color format
Stack: - onUpdate() at (my drawBitmap2 line ...)
I've tried changing the drawable bitmap definition attributes to no avail.
Is it just device file bugs? Making sure the compiler.json files contain an imageFormats section containing png solves the simulator problem at least ...
Currently using 7.2.1.
Also, see bitmap native color format venusq2 discussion.
