Jetpack Compose 未在屏幕截图中捕获 rememberImagePainter

Question

我正在使用中的以下代码将我的可组合函数绘制到 canvas，然后将图像保存给用户 phone，效果很好，直到我在我的 Image 可组合项中使用 rememberImagePainter，并且在应用程序崩溃时不给我任何错误消息。

val bounds = capturingViewBounds ?: return@clickable
bitmap = Bitmap.createBitmap(
    bounds.width.roundToInt(), bounds.height.roundToInt(),
    Bitmap.Config.ARGB_8888
).applyCanvas {
    translate(-bounds.left, -bounds.top)
    view.draw(this)
}

我正在根据 if 语句将来自网络的 PNG 图像直接加载到此图像可组合项中。如果我在图像上使用文件夹中的普通可绘制对象，没有问题，只是当我从网络加载图像时它崩溃了

Image(
    modifier = Modifier
        .align(Alignment.CenterHorizontally)
        .size(48.dp),
    painter = if (player.playerImageUrl.isNotBlank()) {
        rememberImagePainter(data = player.playerImageUrl)
    } else {
        painterResource(
            id = setKitColour(kitColour)
        )
    },
    contentDescription = null
)

private fun setKitColour(color: String): Int {
    return when (color) {
        "Red" -> R.drawable.ic_shirt_red
        "Blue" -> R.drawable.ic_shirt_blue
        "Green" -> R.drawable.ic_shirt_green
        "Yellow" -> R.drawable.ic_shirt_yellow
        "White" -> R.drawable.ic_shirt_white
        else -> R.drawable.ic_shirt_black
    }
}

doesn't give me any error message when the app crashes

事实并非如此，至少在我的情况下我遇到了以下异常：

java.lang.IllegalArgumentException: Software rendering doesn't support hardware bitmaps

这是Coil中的一个known problem，可以通过指定allowHardware(false):

来修复

线圈2.0.0版本：

Image(
    rememberAsyncImagePainter(
        ImageRequest.Builder(LocalContext.current)
            .data(data = imageURL)
            .allowHardware(false)
            .build()
    ),
    contentDescription = null
)

线圈1.4.0版本：

Image(
    rememberImagePainter(
        data = player.playerImageUrl,
        builder = {
            allowHardware(false)
        }
    ),
    contentDescription = "..."
)
