Project Overview
I am looking for an experienced Android application developer who can redesign and rebuild the existing application with a completely new UI/UX while maintaining all its existing features, functionalities, APIs, and database connectivity.
I need a complete, fully functional APK that I can hand over to my in-house developer for future maintenance and development.
Project Requirements
1. Remove Existing Login & Subscription System
- Remove the existing subscription and login system.
- Remove the existing payment-related restrictions.
- Keep all other existing features and functionalities intact.
2. Maintain Existing Database & Backend
- Preserve the existing database connectivity.
- All existing features must continue working with the actual backend and database.
- Maintain existing APIs, data structures, and backend functionality.
- Do not remove, disable, or replace any existing features.
3. Custom Login & Registration System
- Modify the login and registration flow according to my requirements.
- When a user opens the application for the first time, they must register using their mobile number.
- User mobile numbers and registration details must be stored in my database.
- The registration system must be connected to my backend.
4. Custom Payment Gateway Integration
- Remove the existing payment gateway integration.
- Integrate my preferred payment gateway.
- I need complete control over payment processing, subscription management, payment verification, and related logic.
- Payment-related functionality must be configurable through my backend.
5. Complete UI/UX Redesign
- Completely redesign the existing application's interface.
- Create a modern, clean, professional, and user-friendly design.
- Improve navigation, screen layouts, menus, and overall user experience.
- Organize all existing features into a well-structured interface.
- Ensure compatibility with different Android screen sizes.
6. Application Branding
- I will provide the new application name and logo.
- Replace the existing branding with my new branding.
- Update the application icon, splash screen, app name, and other branding elements.
7. Preserve Existing Functionality
- The redesign must not affect existing APIs, database connections, or backend operations.
- All existing features must work exactly as intended.
- Only the login, registration, payment system, and UI/UX should be modified.
Final Deliverables
The developer must provide:
1. Complete redesigned Android application.
2. Fully functional and installable APK.
3. New mobile number-based registration system.
4. User registration connected to my database.
5. Custom payment gateway integration.
6. Existing database and API connectivity maintained.
7. Complete Android Studio source code.
8. Backend/API integration details and configuration files.
9. Build instructions and project dependencies.
10. Final tested APK with all features working properly.
Important Technical Requirements
Before starting development, the developer must:
- Analyze the existing application architecture.
- Examine its existing APIs and database integration.
- Understand the complete application workflow.
- Identify all existing features and dependencies.
- Confirm that the existing backend can continue supporting the redesigned application.
Important: I do not need just a UI design, prototype, or demo APK. I need a complete working application with all existing features operational and properly connected to the actual backend and database.
The complete source code must be handed over to me so that my own development team can independently maintain, modify, and continue developing the application in the future.
Developer Qualifications
- Strong experience in Android application development.
- Experience with APK analysis and application migration.
- Knowledge of REST APIs, backend integration, and databases.
- Experience implementing mobile number-based authentication.
- Experience integrating payment gateways.
- Ability to redesign existing applications without breaking their functionality.
When Applying, Please Provide:
1. Your previous Android application development projects.
2. Your experience with existing APK analysis and rebuilding.
3. Your proposed technical approach.
4. Estimated development time.
5. Total project cost.
6. Confirmation that you will provide the complete source code and all project files.
I am looking for a reliable developer for a complete application redevelopment project, with potential for long-term collaboration.
