Saya ingin membangun sebuah aplikasi Android yang sudah dilengkapi fitur pembelian dalam aplikasi (in-app purchase). Fokus utama saya saat ini adalah merilis versi Android terlebih dahulu; ke depannya, opsi cross-platform tetap terbuka, namun untuk proyek ini saya hanya memerlukan Android. Ruang lingkup pekerjaan: • Merancang dan mengembangkan aplikasi Android native atau menggunakan framework yang tetap menghasilkan performa setara native. • Mengintegrasikan Google Play Billing secara aman, termasuk alur pembayaran, verifikasi, dan penanganan langganan atau item satu kali beli. • Menyediakan antarmuka pengguna yang bersih dan intuitif, beserta alur onboarding singkat. • Menerapkan basis data lokal atau cloud (silakan rekomendasikan yang paling efisien). • Menyerahkan source code terstruktur, petunjuk build, dan satu versi rilis (APK/AAB) siap unggah ke Google Play Console. Kriteria keberhasilan: – Semua transaksi in-app terproses tanpa error dan tercatat di konsol pengembang. – UI/UX responsif di berbagai ukuran layar Android populer. – Kode dapat dibangun ulang di lingkungan standar Android Studio tanpa dependency tersembunyi. – Dokumentasi singkat berisi cara menambah item pembelian baru di masa depan. Bila Anda pernah mengimplementasikan Google Play Billing atau fitur serupa, sertakan contoh aplikasi atau repositori publik. Saya menantikan solusi yang stabil, mudah dirawat, dan siap di-scaling.

I've built Android apps with Google Play Billing before, and I see your core challenge here: getting in-app purchase logic solid and maintainable while keeping the UI clean across device sizes. The fact that you're thinking about future cross-platform options tells me you want a codebase that's structurally sound from day one, not a quick hack. I'd prioritize getting the billing flow bulletproof first - that means solid transaction verification, proper error handling, and a clear pattern for adding new items down the line. For the database layer, I'd recommend starting with local SQLite for simplicity, then documenting how to swap in cloud sync later if needed. On the UI side, I'd build with standard Android components that scale naturally rather than chasing every device variation. I've shipped apps to Play Console before and know exactly what needs to be in place - the AAB setup, the testing checklist, and how to structure your signing keys so you're not stressed about it. If you want to get into specifics about your app's core feature set or timeline, I'm here to figure it out. Corné

Your primary requirement is a stable Android application integrated with Google Play Billing for secure digital transactions. I can build the application using Flutter or React Native with clean architecture, fully implementing Google Play Billing API for both subscription and one-time purchase flows. To ensure transaction integrity, I will implement cloud-based backend receipt verification using Node.js or Laravel, preventing fraudulent purchases before unlocking features. You will receive structured source code, Android Studio build documentation, and a ready-to-upload AAB package. Similar API-driven mobile and web architectures are demonstrated in my portfolio: https://www.freelancer.com/u/albertc1996/14046021 and https://www.freelancer.com/u/albertc1996/14024890. Are your in-app purchase items strictly one-time products, or will you also require recurring subscription management? I can review the exact product list once details are provided.

Anda membutuhkan aplikasi Android dengan alur pembelian yang tidak hanya berhasil di perangkat, tetapi juga tervalidasi dan tercatat dengan benar di Google Play. Saya membangun aplikasi Flutter serta sistem pembayaran, webhook, dan langganan dengan pemisahan yang jelas antara status klien dan verifikasi server. Saya merekomendasikan Flutter agar rilis pertama tetap fokus pada Android sekaligus membuka jalur iOS tanpa menulis ulang aplikasi. Google Play Billing akan menangani produk sekali beli atau langganan, acknowledgement, consumption, restore purchase, pembatalan, transaksi tertunda, dan kegagalan jaringan. Token pembelian tidak akan dipercaya hanya dari perangkat. Backend ringan berbasis Firebase akan memverifikasi transaksi melalui Google Play Developer API, menyimpan entitlement pengguna, dan memproses perubahan status melalui notifikasi real-time. UI akan mencakup onboarding singkat, status loading/error yang jelas, dan tata letak responsif. Source code, konfigurasi environment, build APK/AAB, serta panduan menambah produk baru akan disertakan. Apakah produk Anda berupa langganan, pembelian sekali pakai, atau keduanya?

You need an Android app with in-app purchase capabilities and I will start by setting up the Google Play Billing Library. I will build this using Android native development with Kotlin, using the official Google Play Billing Library v6 for payment processing and subscription management, also I will implement a secure server-side verification for purchases to prevent fraud. The user interface will be designed with Material Design principles for clarity, including a simple onboarding flow. For the database, I recommend Firebase Firestore for its real-time capabilities and efficient data synchronization, so it will store user data and purchase history. I will not be using a third-party SDK for in-app purchases; Google Play Billing Library is the standard and directly integrates with the Play Store, also it provides all the necessary security and features out of the box. How will the app handle returning users who have already made a purchase and are coming back to the app? 8 reviews on here, everything delivered on time and on the agreed price so far, plus Preferred Freelancer status.

Hi there. This is an interesting project. Before anything else, one area I'd pay particularly close attention to is the integration of Google Play Billing, as a seamless payment experience is crucial for user satisfaction and retention. Your focus on a clean user interface and efficient database will be key. I recommend using Firebase for cloud storage due to its scalability and ease of integration with Android apps. This will not only streamline your data management but also enhance the overall user experience. I have implemented in-app purchases in previous projects, ensuring all transactions are error-free and well-documented. What specific features or items do you envision for the initial launch? Looking forward to engaging. Even if we don't end up working together, you'll still walk away with valuable insights from our discussion. Regards, Riyaaz

I have read your requirement and can develop the Android app with a secure and reliable Google Play Billing integration. I’ll implement the complete purchase flow for both one-time products and subscriptions, including product loading, purchase handling, purchase verification, restore purchases, subscription status and proper error/cancellation handling. I’ll also structure the billing layer cleanly so new products can be added later without changing the core app. For the app itself, I’ll build a responsive Android UI with a simple onboarding flow, efficient local/cloud data handling, and clean Android Studio project structure without hidden dependencies. I’ll thoroughly test the billing flow using Google Play test tracks before preparing the final AAB. You’ll receive the complete source code, build instructions, release-ready APK/AAB and documentation explaining how to add future in-app purchase items. Please message me with your app requirements and preferred tech stack. I can review the scope and start promptly. Best Regards Prachi Webix Infotech
