Coil doesn't support SVG by default.

According to documentation, you need to:

1. Add following dependency:

   implementation("io.coil-kt:coil-svg:$coil_version")
   

2. Set SvgDecoder as decoder:

   Coil 2.0.0 version:

   AsyncImage(
       model = ImageRequest.Builder(LocalContext.current)
           .data(svgImageUrl)
           .decoderFactory(SvgDecoder.Factory())
           .build(),
       contentDescription = null
   )
   

   Coil 1.4.0 version:

   Image(
       rememberImagePainter(
           data = svgImageUrl,
           builder = {
               decoder(SvgDecoder(LocalContext.current))
           }
       ),
       contentDescription = null
   )
   

p.s. note that if you set the decoder this way, Coil will not be able to work with non-SVG images in this painter, so if you want some general solution, you should check the url extension and add the decoder accordingly.

I was working on Jetpack Compose app and the urls I received from a remote API contained both .png/jpeg and .svg file extensions.

I added dependencies for both Coil Compose and SVG flavors for Coil Version 2.0.0 which is the latest version as of January 2023.

// Coil
implementation("io.coil-kt:coil-compose:2.2.2")
implementation("io.coil-kt:coil-svg:2.2.2")

I then chained decoderFactory(SvgDecoder.Factory()) to Image.Request builder.

val painter = rememberAsyncImagePainter(
                model = ImageRequest.Builder(context = LocalContext.current)
                    .data(urlPng or urlSvg)
                    .decoderFactory(SvgDecoder.Factory())
                    .error(R.drawable.empty_flag)
                    .placeholder(R.drawable.empty_logo)
                    .build()
            )

            Image(painter = painter, contentDescription = null)
            

The updated .components { add(SvgDecoder.Factory())} call mentioned by @jendress was not resolved in my case and so I went with decoderFactory().

Both urls with .png/.jpeg and .svg worked well and rendered the correct image without errors.

The syntax for adding a new decoder has changed a bit from 1.4.0 to 2.x.x.

val imageLoader = ImageLoader.Builder(context)
.components {
    add(SvgDecoder.Factory())
}
.build()

You can find the latest syntax here: https://coil-kt.github.io/coil/svgs/
