Project description:
"I’m putting together an Android-only application and need an expert to walk me through everything involved in adding Google Play Billing as the core feature. Although I can handle basic Android Studio tasks, I want a clear, end-to-end understanding of best practices before I write a single production line of code.

Here’s what I’d like from you:

• A live or recorded technical walkthrough that covers project setup, Play Console configuration, and secure purchase-token handling.
• A small, clean sample project (Kotlin or Java) that compiles error-free in the latest Android Studio and demonstrates consumables, non-consumables, and subscription flows.
• A brief write-up explaining sandbox testing, common pitfalls, and the steps required when publishing an update that enables billing.

Acceptance will be based on your sample project running successfully in the sandbox environment and your explanations being detailed enough for me to replicate the process independently.

If you’ve already shipped apps with in-app purchases, please share a link or two so I can quickly verify your experience. Also let me know your timezone and preferred format for the walkthrough so we can schedule a session that works for both of us." (client-provided description)
