Fix maxBitmapSize calculation with FILL for preventing too large bitmap crash on Android platform

[irgaly]

AsyncImage on Compose will exceeds maxBitmapSize limitation, and leads crash on some Android platforms.

• relates: Load very big image throw OOM #1349

Reproducer

• platform: Android 14 Emulator
• coil v3.3.0
• Reproducer condition:
  • The image has larger size than maxBitmapSize
  • The incoming constraints of AsyncImage are Infinity
  • The Scale config is FILL

Box(Modifier.padding(padding)) {
    Column(
        Modifier
            // IntrinsicSize leads the constraints to Infinity
            .width(IntrinsicSize.Max)
            .background(Color.Yellow.copy(alpha = 0.4f))
    ) {
        AsyncImage(
            model = ImageRequest.Builder(LocalPlatformContext.current)
                // 8000px x 4000px image
                .data("https://placehold.jp/8000x4000.png")
                .build(),
            contentDescription = null,
            Modifier.fillMaxWidth().aspectRatio(4f / 1f),
            // ContentScale.Crop is used on calculation as FILL
            contentScale = ContentScale.Crop,
        )
        Text("Title text")
        Text("Body text. Body text. Body text.")
    }
}

This layout is like this:

In this example, the AsyncImage receives Infinity constraints in ConstraintsSizeResolver.

Then, resolved size is Size(width = Undefined, height = Undefined) (Size.ORIGINAL).

Then, DecodeUtils.computeSizeMultiplier() will calculate as Scale.FILL to (dstWidth, dstHeight) = (4096, 4000). dstWidth is limited to maxBitmapSize. So the multiplier = 1.0f will be used.

Finally, AsyncImage will draw the bitmap with 8000px x 4000px, and this will cause crash on some Android versions (old versions or hardware limitation?).

java.lang.RuntimeException: Canvas: trying to draw too large(128000000bytes) bitmap.

Fix

The problem is DecodeUtils.computeSizeMultiplier(). When it computes with Scale.FILL, the multiplier and resulting bitmap will be larger than the size of maxBitmapSize.

I fixed computeSizeMultiplier() on this PR, by limiting the multiplier after calculating that with FILL or FIT. The multiplier will be limited to the both of the maxBitmapSize.width and the maxBitmapSize.height.

The test with FILL scaling.

I fixed lint error and updated API dump.
