This is the image

import com.tarehimself.mangaz.getPlatform

@Composable
fun SearchResult(data: String) {
    Surface(
        modifier = Modifier.height(300.dp).border(
            width = 2.dp,
            color = Color.Transparent,
            shape = RoundedCornerShape(5.dp)
        ).padding(horizontal = 5.dp, vertical = 5.dp),
        color = Color.Transparent,
    ) {
        when (val resource = asyncPainterResource("https://www.example.com/image.jpg")) {
            is Resource.Loading -> {
                Text("Loading...")
            }
            is Resource.Success -> {
                val painter: Painter = resource.value
                Image(painter= painter, contentDescription = "Profile",modifier = Modifier.fillMaxSize())
            }
            is Resource.Failure -> {
                Surface(
                    modifier = Modifier.fillMaxSize(),

                }
            }
        }
    }
}

And this is the config

@Composable
fun App(){
    val kamelConfig = KamelConfig {
        takeFrom(KamelConfig.Default)
    }

    CompositionLocalProvider(LocalKamelConfig provides kamelConfig) {
        Surface(
            modifier = Modifier.fillMaxSize(),
            color = MaterialTheme.colors.background,

            ) {
            SearchScreen()
        }
    }
}

The error is happening on android

Same issue with 0.9.0

Frankly I gave up and went with my own image loader , it's not all that complicated once you get into it

[Tare]

I can link my repo if you want to see how it was implemented

[Luca Spinazzola]

An error with that example is expected. as that link you are loading is not an image.

Anyways. I just pushed a commit that makes BitmapDecoder errors more descriptive.

Your example will now return on failure:
