Coil 3.0: Images from the network aren't loading

[colinrtwhite]

Opening this preemptively to catch incoming issue when upgrading from Coil 2.0 to 3.0. You need to add one of Coil 3.0's new network dependencies:

implementation("io.coil-kt.coil3:coil-network-okhttp:3.0.4") // Only available on Android/JVM.
implementation("io.coil-kt.coil3:coil-network-ktor2:3.0.4")
implementation("io.coil-kt.coil3:coil-network-ktor3:3.0.4")

This change was made for two reasons:

• Coil now supports multiple networking libraries. You can use OkHttp on JVM/Android and Ktor if you need multiplatform support.
• Coil no longer has a hard dependency on OkHttp so you don't have to import it if you only load images from local sources (file system, content providers, resources, etc.).

You can set a custom OkHttpClient/HttpClient like so:

val imageLoader = ImageLoader.Builder(context)
    .components {
        add(
            OkHttpNetworkFetcherFactory(
                callFactory = {
                    OkHttpClient()
                }
            )
        )
        // OR
        add(
            KtorNetworkFetcherFactory(
                httpClient = {
                    HttpClient()
                }
            )
        )
    }
    .build()
