How to fix “canvas: trying to use a recycled bitmap error”?

Question

I\'m creating a RecyclerView to show a Grid of pictures. When selecting one of them, it should open a new activity with a transition.

I\'m using Glide l

Answer 1

I solved by adding this:

Glide.with(activity).clear(view);

before load the image:

Glide.with(activity)
                .load(imageUrl)
                .apply(options)
                .placeholder(R.drawable.loading_image)
                .error(R.drawable.not_found)
                .into(view);

See docs:

Answer 2

Move bitmap.recycle(); to another place in the code where this bitmap is really no longer needed.

Answer 3

I don't know much about canvas (I don't use animations that often) but if you don't find any way to fix this, you could try using this library instead: https://github.com/codepath/android_guides/wiki/shared-element-activity-transition

Answer 4

I suspect that once in a while your bitmap gets into the recycled state just before the Canvas gets a chance to draw onto it here drawable.draw(canvas);.

A quick solution should be not to call bitmap.recycle();, which is not strictly required for android >2.3.3. If you still want to reclaim this memory forcefully, you'll have to find a way to check when the bitmap is indeed no longer needed (i.e., Canvas had a chance to finish its drawing operations).
