AdaptiveIcon isn't rendered

[apkelly]

Description
I have the following code to fetch and render adaptive icons, specifically the res/mipmap-anydpi-v26/ic_launcher.xml file.

@Composable
fun adaptiveIconPainterResource(@DrawableRes id: Int): Painter {
    val res = LocalContext.current.resources
    val theme = LocalContext.current.theme

    return if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
        // Android O supports adaptive icons, try loading this first (even though this is least likely to be the format).
        val adaptiveIcon = ResourcesCompat.getDrawable(res, id, theme) as? AdaptiveIconDrawable
        if (adaptiveIcon != null) {
            BitmapPainter(adaptiveIcon.toBitmap().asImageBitmap())
        } else {
            // We couldn't load the drawable as an Adaptive Icon, just use painterResource
            painterResource(id)
        }
    } else {
        // We're not on Android O or later, just use painterResource
        painterResource(id)
    }
}

This code work fine in the running app, and fine in the Android Studio preview, but fails with the following error in Paparazzi.

SEVERE: null: Failed to parse file /Users/andy/Development/mx51/vaa-android/x-paparazzi-tests/../core/ui/build/intermediates/packaged_res/geckoBankDebug/mipmap-anydpi-v26/ic_launcher.xml

Steps to Reproduce

1. Create a new Compose project with default icons in Android Studio.
2. Create a new Composable screen and use the method above to display the launcher icon on the screen.
3. Note that the screen renders fine in Android Studio and when run on a phone (Android O or later).
4. Record the paparazzi tests and note that the screen doesn't show the icon.

Expected behavior
The adaptive icon for the launcher icon of my app should be rendered correctly using the code above.

Additional information:

I'm seeing this too on 1.3.2 and 1.3.3. I'm struggling to deal with this on 1.3.3 because even if I handle the exception the test fails as exceptions were logged. Is there an expected fix date or version for this?

[jamesrapadmi]

Is there any update on this, this is still preventing us from updating to 1.3.3 or 1.3.4

If at any point you have access to RenderParams, set the following flag:

setFlag(
    SessionParams.Key("adaptiveIconMaskPath", String::class.java),
    "M50,0L92,0C96.42,0 100,4.58 100 8L100,92C100, 96.42 96.42 100 92 100L8 100C4.58, 100 0 96.42 0 92L0 8 C 0 4.42 4.42 0 8 0L50 0Z"
)

Value taken from $ANDROID_HOME/platforms/android-35/data/res/values/config.xml!string/config_icon_mask.

It's used either in com.android.layoutlib.brige.impl.RenderAction or android.graphics.drawable.AdaptiveIconLayout depending on the version of layoutlib.

I don't have access to RenderParams at any point, you can see the source above
