I need an Android-only MVP that lets customers discover our events, reserve a spot, pay, and then see the confirmed booking appear in their Google Calendar automatically. The flow is straightforward: event list → detail screen → seat/quantity selection → checkout → confirmation. Payment must accept credit or debit cards, popular digital wallets, and direct bank transfers from day one. If you already work with gateways that bundle these (for example Stripe or Razorpay alternatives), let me know which SDK you prefer and why; I’m open as long as all three methods are available to the user inside the app with a single, clean checkout experience. Calendar sync is limited to Google Calendar for this phase. Once a booking is successful the event details, date, time, and location should be pushed instantly to the user’s Google Calendar with a reminder set 24 hours before the event. Guests should also be able to remove or update their reservation and have the calendar entry reflect that change. Because this is an MVP, visual polish can be minimal; stability, simple navigation, and well-structured code matter more. I will want the full Android Studio project, a signed APK suitable for internal testing, and a short read-me that explains the build steps, third-party services used, and where to swap keys or credentials. Please note: I am only considering developers located outside India for this project.

I see you're looking for an Android MVP that integrates Google Calendar for event bookings, along with those payment options through Stripe or Razorpay. And one tricky part is making sure the calendar sync works smoothly, especially when updating or removing reservations. Many developers overlook the need to handle Google Calendar API's quota limits and error responses properly, which can lead to frustrating user experiences, so it's really important to get it right. I'll focus on building a stable app with straightforward navigation, I want to make sure the payment process is clean and supports all three methods right from the start. I’ll provide the full Android Studio project, a signed APK, and just a concise read-me to guide you through setup and integration. I'm ready to get started on this right away for $119, and I think we can make this MVP a success. Rajavel Android Developer | Stripe | Razorpay

Hi, I understand you're looking to develop an Android MVP event booking app that integrates seamlessly with Google Calendar and supports multiple payment methods, including credit/debit cards, digital wallets, and bank transfers. The project requires a smooth user flow from event discovery to booking confirmation. The primary technical challenge here is ensuring the payment gateway integration supports all specified methods from launch, while also maintaining robust security. My approach would involve assessing the most suitable payment gateway that meets these criteria and prioritizing a stable integration that aligns with your MVP scope. Additionally, ensuring the Google Calendar API is correctly implemented for automatic booking confirmation is crucial. I have extensive experience with PHP and payment gateway integrations, having developed similar solutions that prioritize user experience and security. Q1 – Which payment gateways are you considering, and do you have a preference based on your target market? Q2 – Are there any specific requirements or restrictions regarding the Google Calendar integration? Q3 – How do you plan to handle any potential changes in event details post-booking, and should these also update in the user's calendar? Looking forward to hearing from you.

I’ve built similar MVP apps that handle event discovery, booking, and calendar integration. For the payment flow you want, Stripe’s SDK covers credit/debit cards, digital wallets, and bank transfers in one clean checkout. If you prefer alternatives like PayPal or Razorpay, I can advise on the trade-offs and implementation complexity. To sync with Google Calendar, I’ll use the official API for instant event creation and updates, including removals, all with a notification set 24 hours before. This part is straightforward since I’ve done Google Calendar integration for reservations in past projects. A quick question: Do you have your Google API credentials ready, or should I guide you through that setup? Also, would you need user authentication, or is booking open without accounts for now? I’ll deliver a simple but solid Android Studio project with clear documentation, a signed APK for your tests, and well-structured code that’s easy to extend after MVP. Ready to get started as soon as you say!

IF YOU ARE NOT HAPPY YOU DON'T PAY! The part that usually breaks in this flow is the update/cancel sync. When the booking is written to Google Calendar through the Calendar API, the returned event ID has to be stored with the reservation. Without it, a change adds a duplicate entry instead of updating the original. Payment status should also come from the gateway's webhook, not from the app screen, so a dropped connection can't confirm a seat that wasn't paid. I'd deliver the full Android Studio project with list → detail → quantity → checkout → confirmation. You'd also get the 24h reminder, edit and cancel that update the same calendar entry, a signed test APK and a README showing where each key goes. Which country and currency will your customers pay in? That decides whether Stripe or a local gateway can offer cards, wallets and bank transfer in one checkout. Send me a message and I'll explain exactly how I'd approach your project.

I’m based outside India and can build this Android-only MVP as a clean native Kotlin app. I have 9+ years of Android/mobile engineering experience with payments, REST APIs, authentication, Google services, notifications, and Play Store releases. For the MVP I’ll implement: - Event list and details - Seat/quantity selection - Checkout and booking confirmation - Card, wallet, and bank-transfer payment flow - Google Calendar sync after successful payment - 24-hour reminder - Booking update/cancel with matching calendar changes - Signed APK + complete Android Studio project - README with build steps and credential configuration For payments, I’d select the gateway based on your target market and confirm that all three required methods are supported before integration. Stripe or Razorpay-style gateways are suitable depending on region and settlement requirements. The code will be structured for stability and future expansion rather than over-polishing the MVP. I’m available to start immediately.

Hi, Primary risk is payment confirmation timing and Google Calendar consistency: if a user closes the app between payment success and calendar insert, we must guarantee idempotent booking records and use server-side webhooks to confirm payment state before writing or removing events in Google Calendar. Also plan for permission flows, token refresh, and handling refunds/cancels that must update or remove the calendar entry. I built mission-critical systems that processed payments and synchronized external calendars. I led delivery of a payroll API and a tax-filing backend that required reliable webhooks, reconciliation, and secure credential handling; I have implemented Google Calendar API integrations and Android clients that handle OAuth consent and background sync. I can point to similar technical patterns from those projects on request. I will use Stripe Android SDK (PaymentSheet + PaymentIntents) as my preferred gateway because it supports card payments, Google Pay, and server-driven bank transfers/ACH flows in a single integration and has mature webhooks for confirmation and refunds. If you prefer another provider that bundles cards, wallets, and direct bank transfers, I can adapt quickly, but Stripe reduces integration complexity for an MVP. Implementation begins with a small server (Node or .NET) to host payment intents, manage bookings, and process Stripe webhooks; Android app will call that API. On successful payment webhook the server will create/update the Google Calendar entry via users' OAuth tokens and send status to the app. Cancellation or quantity changes trigger webhook-driven calendar updates. I will deliver the full Android Studio project, signed APK, and a concise read-me showing build steps, where to swap keys, and webhook setup. - Do you prefer Stripe or should I present an alternative gateway with comparable card/wallet/bank support? - Do you want bookings tied to user accounts (email+OAuth) or allow guest checkout with calendar OAuth per booking? Always up for a quick conversation if you have questions. Thomas Beigbeder

Hi, Fernando from Mexico. I want to build the Android MVP around the complete booking flow: event discovery, seat selection, multi method checkout, confirmed booking and Google Calendar synchronization. I’d use Android Studio with a clean MVP structure, PHP for the backend and a payment gateway supporting cards, wallets and bank transfers. NexoraTec works across mobile development, PHP, APIs and payment integrations. I’ll first implement event listing through successful booking and calendar creation, so the complete core flow can be tested before adding booking updates and cancellation handling. Should payments use Stripe or another gateway already available to your business, as this changes the SDK and bank transfer implementation? For Google Calendar, should users sign in with Google OAuth or use calendar authorization only after payment, as this changes the authentication and consent flow? Bests
