superwall/Superwall-Android ? reverse-engineered prompt

Build me an Android SDK for in app paywalls that can be controlled remotely, so I can change the paywall without shipping a new app update.

I want it to work in Kotlin, with support for Java too, and to present the paywall inside the app using a WebView based screen. It should include the basic setup for adding it to an app, showing a paywall, and handling the main SDK flow cleanly. Please also include the tracking pieces for paywall views, conversion, trial starts, and simple analytics so I can see what is working. If it makes sense, add a debug mode or console screen for testing paywalls and localizations.

Use the current docs online if you need to confirm best practices, and make it feel like a real production library with a small example app or sample usage so I can try it quickly.
