The bottleneck is migrating the existing Stripe in-app purchase flow to Google Play Billing without disrupting current customers. The root cause is the need to integrate Google Play Billing's API while preserving backend membership activation consistency. I will update the Android SDK and project to the latest standards, implement Google Play Billing hooks matching the current backend endpoints, and ensure seamless data flow for subscription activation. I will rebuild the signed .aab package and publish it to the production track, validating subscription integrity across platforms. What are your critical success criteria for verifying subscription integrity after migration?

@AndrewJSMAN

I’ve updated Play Billing flows in three Android apps, migrated Stripe to GPB for two of them, and handled SDK upgrades + signed .aab builds before. This is right in line. I’ll open the project in Android Studio Giraffe, bump all SDKs and dependencies to current stable, apply Google’s security policies and perf flags, then strip the Stripe module and wire in GPB v5 subscriptions and one-time purchases. A/B product IDs will map exactly to your backend SKUs so web/iOS parity is preserved; I’ll stub the real calls so you can slot them in later without breaking live users. After local validation, I’ll sign with your keystore, run a full Play Console upload, and publish to production track. All modified files will be in the returned project.

I can take the existing WombWisdom Android project through the complete Version 7 production release, including SDK/toolchain upgrades, UI/security/performance updates, signed AAB generation, Google Play Billing migration, testing, and production deployment. I’d first audit the current Gradle/Android configuration, dependencies, target SDK requirements, Stripe purchase flow, keystore, and existing backend contract. I’ll then migrate purchases to Google Play Billing, ensuring purchase verification and membership activation continue through your existing backend while keeping current web/iOS customers unaffected. The release process will include: Latest required Android SDK/toolchain migration Dependency/security updates and compatibility fixes UI/performance improvements identified during the upgrade Google Play Billing for subscriptions/in-app purchases Restore purchases and existing membership handling Signed .aab using your original keystore Internal/testing track validation before production Production Play Store submission Final Android Studio project with all changes documented I’ll pay particular attention to existing subscriptions, account mapping, purchase restoration, and backend verification so the migration does not disrupt current members. I’ll flag any additional customizations discovered during the audit before implementing them.

@demivision

Hi there, Employer, Thank you for outlining your requirements for updating the WombWisdom Android app. I understand you need to upgrade the project to the latest Android SDK, implement required UI and security improvements, optimize performance, and—most critically—migrate all in-app payments from Stripe to Google Play Billing, ensuring an uninterrupted experience for current users. You also require the updated project to be signed with your original keystore and published to the production track on Google Play, with validation that subscriptions and accounts remain consistent across platforms. With extensive experience in Android development, including SDK upgrades, Play Billing integration, and production releases, I am confident I can deliver a seamless transition. I have successfully migrated payment systems on several apps, ensuring strict compliance with Google’s latest policies and maintaining a smooth experience for existing subscribers. My background in both Java and PHP, alongside hands-on use of Android Studio and the Android SDK, positions me well to support your backend integration and guide any necessary adjustments. My approach would begin with a detailed assessment of your current codebase to identify areas needing modernization or optimization. I’ll then update dependencies, apply recommended security and performance enhancements, and revamp the payment flow to use Google Play Billing. Throughout, I’ll collaborate with you to verify backend endpoints, test for edge cases, and confirm all user data, purchases, and memberships remain unaffected. Once fully tested, I will publish the new bundle to production and provide you with the complete updated project. If you have additional enhancements in mind, such as minor UI tweaks or accessibility improvements, I’d be happy to discuss integrating those alongside the main update. Looking forward to working together to bring WombWisdom to its next release!

Hi there! I understand you need WombWisdom updated to the latest Android SDK and rebuilt as a signed .aab for Version 7, while keeping existing users and subscriptions safe. The main challenge is replacing Stripe with Google Play Billing without breaking the existing membership flow or affecting customers across Android, web, and iOS. I have relevant Android development experience with Android Studio, SDK upgrades, payment integrations, backend API connections, security updates, and performance optimization. My approach will be to first review the current project, Gradle setup, SDK requirements, and existing Stripe flow. I will then implement Google Play Billing and connect purchases with your existing backend endpoints. I will test new and existing subscription scenarios carefully before preparing the signed bundle and production release. I will also provide the complete updated Android Studio project with all modified source files and clearly flag any additional customizations before adding them. check our work [https://www.freelancer.com/u/ayesha86664] Could you share the current Android Studio project and confirm the target SDK required for Version 7? Let me know if you’re interested & we can discuss it. Best Regards Ayesha

@lazarr4

Hello, the biggest risk here is breaking existing subscriptions or billing flows during migration, since Play Billing has stricter validation and edge cases that the old Stripe integration might not handle. I’ve updated a few Android apps to Play Billing recently, mainly dealing with legacy payment systems and version jumps. The core is usually handling the new billing client, AIDL changes, and making sure purchase tokens map cleanly to your backend. I’d pull the latest Android Studio, bump all SDKs, then swap the Stripe code for Play Billing without touching the backend contract. After local testing I’d push a signed aab to internal track, validate upgrade paths and new purchases, then publish to production. If any stray edge cases pop up, we’ll patch them before final release. Let me know if you want the Play Console setup checked or any small tweaks folded in. Thanks, Lazar.

Hi. I can open the WombWisdom Android project, update it to the latest SDK, and rebuild it for you. I've worked extensively with Android App Development using Java and Android Studio, migrating legacy projects to current SDK versions and resolving dependency conflicts. My experience with Mobile App Development and the Android SDK covers updating build configurations, updating target API levels, and ensuring compatibility with newer Android versions. I've also handled PHP backends that connect to Android apps, so if WombWisdom has server-side components I can verify those integrations still work after the rebuild. - Open the project in Android Studio and audit the current SDK version, dependencies, and deprecated APIs - Update Gradle files, target SDK, and compile SDK to the latest stable versions while resolving any breaking changes - Rebuild the app, test on current Android devices, and verify all features including Play Billing integration if it's already implemented Are you planning to update Play Billing to the newer Google Play Billing Library version, or just ensure the current implementation compiles and runs on the updated SDK? I can start right away and keep you updated through Freelancer messages as I work through the migration. Best regards, Jordan Rafael
