@NEHABHAT92

As a seasoned Android developer with over a decade of experience, I'd be thrilled to assist you in adding Google Play Billing to your Android app. Throughout my extensive career, I've worked on numerous projects involving in-app purchases and have successfully navigated the sometimes complex process of integrating these features. With me, you'll get far more than just a 'how-to' guide - you'll gain comprehensive insight into best practices and industry standards. Over the years, I have developed a streamlined and effective approach to project delivery that prioritizes clear communication, efficiency, and high-quality output. My team at NehaTech not only has deep proficiency in Android development but also in responsive website design - which is an added advantage since we can provide coherent guidance on handling billing across different platforms if needed. Additionally, my role has frequently involved creating mini-sample projects that precisely exhibit various features and flows for better comprehension. Providing sandbox testing instructions, outlining common pitfalls, and offering a step-by-step plan for future updates would be no hurdle for me. Overall, I am confident I can offer significant knowledge and a reliable support system to bring your in-app payment feature alive on Android.

@utpalmv

Hey there, I’ve implemented Google Play Billing in live Android applications and can guide you through the complete process before you write production code. This includes Play Console configuration, product setup, secure purchase-token handling, and understanding how Google expects billing flows to work in real-world apps. I can provide a clean, production-ready sample project (Kotlin or Java) that demonstrates consumables, non-consumables, and subscriptions, tested in the sandbox environment. I’ll also explain common pitfalls, testing flows, and what changes when enabling billing in an update so you can implement it confidently on your own. If you’d like to move forward, drop me a message with your timezone and preferred format (live walkthrough or recorded), and we can schedule the next steps. Best, UV

@sefunmioluyede55

Hello, I can support this as Project Manager / Technical Coordinator, working with a senior Android developer from Metasyn Enterprise Solutions who has implemented Google Play Billing (consumables, non-consumables, subscriptions) in real Android deployments. What you’ll receive (end-to-end, replicable): Walkthrough (live or recorded): Android Studio setup, Play Console configuration, product setup, licensing/test accounts, and secure purchase-token verification/handling (incl. recommended server-side validation patterns and client-side best practices). Clean sample project (Kotlin): Builds error-free on the latest Android Studio and demonstrates consumable, non-consumable, and subscription flows with clear structure and comments. Short written guide: Sandbox testing steps, common pitfalls (acknowledgement, pending purchases, signature/token handling, subscription states), and publishing an update that enables billing. Acceptance focus: Sample app runs successfully in the sandbox environment, and documentation is detailed enough for you to implement independently. Notes on portfolio: Some shipped apps are under NDA, but we can walk you through architectures, billing flows, and implementation decisions during the session, and we can share anonymised screenshots/code patterns where appropriate. Best regards, Oluwasefunmi Oluyede
