Walkthrough

The Android playground app's debug manifest (apps/playground/android/app/src/debug/AndroidManifest.xml) is updated to include an <application android:usesCleartextTraffic="true" /> entry. This change is scoped to the debug source set and permits plaintext HTTP traffic, enabling a locally served WebView runtime script to load during development. Comments in the file note that this setting is not applied to release builds.
