As i remember BitmapFactory.decode* can create sacaled images from file of data without creating big image. do you try this approach ?
ill try that
Size: a a a

however, this would require that i decompress inside of onDraw
MG
i might be able to do it inside of setBitmapImage, tho im not sure if that would work
MG
wait that would interfere with my recording since it would store pre-scaled images instead of original scale images
MG
tho i could just have it store the cache directly...
MG
ok, so it crashed, i fixed the crash, and now it is broken
MG
setImageBitmap: measured
scale: scaling bitmap from 1440x2844 to 16777215x16777215
MG
aaand
resolveAdjustedSize cannot be called if the view is not attatched to anythingMG
ughhhhhh
MG
welp lets try setting it in onViewAttatchedToWindow
MG
nope, still doesnt work

any ideas how to do this WITHOUT doing it in onDraw?

you can do it in background. after you know exact values of scale. (on measure is a good point).
MG
btu you said that i shouldnt create objects in onMeasure
MG
also onMeasure can return false values since it is usually called multiple times on the same view before a final measurement
MG
so it would also produce multiple un-needed scaled bitmaps
MG
which is why i do my scaling in onDraw, as it is the only place i can be gaurenteed of correct measurements

how i will solve this problem:
1) onMeasure/onLayout/onDraw calculate what scale we need.
2) If current cached value is not valid - launch coroutin that will prepare image for needed scale
3) when corouting finished - set new cached scale and image and force view to redraw

what function will trigger background task - depends on your layout. onDraw indeed will be best place in most cases
