@cartland could you please check if these file locations make sense?

Every time someone merges a pull request, you will need to rebase on top of the main branch. Sometimes this is easy, but if there are conflicts you will need to resolve them.

The package should match the directory structure after /java. In this case, it should be com.example.snippets.jetpackwebkit

[cartland]

This snippet is supposed to match the snippet here:
https://developer.android.com/develop/ui/views/layout/webapps/jetpack-webkit-overview

// You still get your WebView instance the standard way.
val webView: WebView = findViewById(R.id.my_webview)

// To enable a modern feature, you pass that instance to a Jetpack Webkit helper.
if (WebViewFeature.isFeatureSupported(WebViewFeature.FORCE_DARK)) {
    WebSettingsCompat.setForceDark(webView.settings, WebSettingsCompat.FORCE_DARK_ON)
}

This snippet also adds additional code:

        // This is necessary to keep navigation inside your WebView
        webView.webViewClient = WebViewClient()

        // Enable JavaScript
        webView.settings.javaScriptEnabled = true

Is this additional code expected and required?

It wouldn't harm to retain these lines of code, so prefer to retain.

We should not add a new module. We should edit the build file for the existing misc module.

We should not add a new Gradle version catalog. We should edit the existing version catalog.

https://github.com/android/snippets/blob/main/gradle/libs.versions.toml

The name of this file appears to be a layout but the contents is an Android manifest file.

The code snippet uses R.layout.activity_main so you need the manifest file to match, activity_main.xml.

https://developer.android.com/guide/topics/resources/layout-resource

Then the contents will need to be updated to be a layout. For the snippet to compile, it can be a very simple layout file.

The original snippet has the imports. To include the snippets in the region tag, it would be easiest to include them as comments here. Region tags around the real imports above would not be stable because our style formatting tools in Android Studio and Spotless will reorder imports and comments, which would break region tags if you try to use them up there.

// import android.webkit.WebView
// import androidx.webkit.WebSettingsCompat
// import androidx.webkit.WebViewFeature
