Hello, my name is Hiren Kapuria, and I specialize in Android development with strong experience integrating secure third-party services like payment gateways, Firebase, and Google APIs. I’ve carefully reviewed your requirement to push a new release of your existing Android app by adding a production-ready payment solution while keeping the rest of the build stable. Here’s how I will approach it: Integrate Stripe (or equivalent) with Google Play Billing Library v5+ for full policy and PCI compliance. Implement one-time payments now, structuring the module for future subscription support. Deliver a clean, modular payment package with clear comments for maintainability. Prepare a signed AAB ready for Play Console rollout plus a debug build for testing. Provide step-by-step documentation for console configuration (keys, SHA-1, billing settings). Share a test plan validating successful payments, refunds/cancel flows, and compliance checks. You’ll also receive support during testing to ensure zero crashes/ANRs and smooth pre-launch verification. With your Git repo and merchant sandbox, I can complete this quickly and reliably. Let’s collaborate to make this release seamless and compliant, so your users get a secure and smooth checkout experience. Best regards, Hiren Kapuria
