java.lang.IllegalStateException: BitmapFactory returned a null bitmap. Often this means BitmapFactory could not decode the image data read from the input source (e.g. network, disk, or memory) as it's not about coil HOT 5 CLOSED

I tried clearing the local cache data and reinstalling to no avail. Apparently this has something to do with loading links.

Your image is very tall (18,000 pixels) and the size isn't being constrained based on your ImageRequest. You need to set a bounding size and likely set scale(Scale.FIT) to ensure the image is decoded into memory at a smaller size (2000x2000 should be safe).

EDIT: I'd recommend using something like Telephoto for viewing this image as it has optimizations related to showing partial images on screen and panning and zooming. It has integrations with Coil.

Is there any other way to solve this problem? I added scale fit but it has no effect, and this problem will definitely occur with 20588 pixels.
Scale loads 18000 pixels high with no problem
But something went wrong when it reached 20588

.decoderFactory { source, options, loader ->
                    decoder{
                        val Bitmap = BitmapFactory.decodeStream(source.source.source().inputStream())
                        val result = DecodeResult(drawable =bitmap.toDrawable(app.resources), false)
                        result
                    }
                }

I checked the source code and rewrote decodeFactory. Now the 23,000 pixel high image has been loaded and is very clear. I'm not sure what the risks are with this implementation? And I think the implementation of BitmapDecode in the source code is relatively complicated. Should I pay attention to some more important logic for custom implementation? Can you give me some suggestions?
