Does Coil support imageByteArray?

[clint22]

When I'm trying to pass imageByteArray as a parameter into the load function it's throwing some error such as 'None of the following functions can be called with the argument supplied'. But it's working perfectly using Glide. Sharing my code snippet of what I have done using Coil and Glide.

Using Coil

val imageBytes = it.locationImage
val imageByteArray = Base64.decode(imageBytes, Base64.DEFAULT)

ivFloorMap.load(imageByteArray) {
crossfade(true)
placeholder(R.drawable.image_placeholder)
transformations(CircleCropTransformation())}

Using Glide

val imageBytes = it.locationImage
val imageByteArray = Base64.decode(imageBytes, Base64.DEFAULT)

Glide.with(context)
.asBitmap()
.dontTransform()
.placeholder(R.drawable.image_placeholder)
.load(imageByteArray)
.into(ivFloorMap)

Did anyone face the same issue?

It's not part of the base library, but it could be added pretty easily with a custom Fetcher:

class ByteArrayFetcher : Fetcher<ByteArray> {

    override fun key(data: ByteArray): String? = null

    override suspend fun fetch(
        pool: BitmapPool,
        data: ByteArray,
        size: Size,
        options: Options
    ): FetchResult {
        return SourceResult(
            source = ByteArrayInputStream(data).source().buffer(),
            mimeType = null,
            dataSource = DataSource.MEMORY
        )
    }
}

You can then add it to your ComponentRegistry when constructing the default ImageLoader. Check out here for an example.

Once that's done you can call imageView.loadAny(imageBytes) and it should work.

Wow. It worked perfectly. Thank you.

For all finding this issue in 2022:
2.1.0 has added support for ByteArray, see: https://github.com/coil-kt/coil/blob/main/CHANGELOG.md#210---may-17-2022 & #1202
