Who's Responsible for What in an Android Development Project
Definitive role matrix breaking down what the client provides (vision, API endpoints, brand assets) vs what Prap Techie executes (architecture, Kotlin code, QA, Play Store submission).
Unclear expectations cause more software project delays than technical bugs. When a client assumes the developer is handling privacy policy legal drafting, or a developer assumes the client is writing backend API documentation, sprints grind to a halt.
To guarantee zero friction and on-time delivery, we establish a crystal-clear division of responsibilities before kick-off. Here is the definitive breakdown of what you bring to the table as the client, and what Prap Techie executes as your studio.
1. What the Client Is Responsible For
As the product owner, your inputs define the business direction and scope boundaries of the project.
Core Client Responsibilities:
- Product Vision & Feature Scope: Defining what problem the app solves, key user personas, and the core V1 feature list.
- Backend API Endpoints & Access: Providing operational REST/GraphQL endpoints, API documentation (Swagger/Postman), or access to Firebase environments.
- Brand Assets & Copy: Supplying high-resolution logos, brand color codes (HEX/HSL), app icon graphics, and specific marketing text copy.
- Third-Party Developer Accounts: Maintaining active ownership of your Google Play Console developer account ($25 one-time registration fee with Google), payment merchant accounts (Stripe/PayPal), and third-party API keys (OpenAI, Firebase, Maps).
- Timely Sprint Feedback: Reviewing weekly APK/TestTrack builds and providing consolidated feedback within agreed-upon sprint windows.
2. What Prap Techie Studio Is Responsible For
As your dedicated engineering studio, we handle the complete technical translation of your vision into production-grade software.
[ CLIENT INPUTS ] [ STUDIO EXECUTION ]
• Product Vision & Features ──► • Clean Architecture Blueprint
• Backend Endpoints & Keys ──► • Kotlin & Jetpack Compose UI
• Brand Assets & Copies ──► • Room Offline Persistence Layer
• Google Play Console Account ──► • API Binding & Coroutines Engine
• Sprint Build Review ──► • Device QA & Play Store Submission
Core Studio Responsibilities:
- Technical Architecture & Blueprint: Crafting scalable MVVM/MVI clean architecture using modern Kotlin 2.0.
- Declarative UI Engineering: Building 60 FPS responsive visual interfaces with Jetpack Compose tailored for phones and foldables.
- API Integration & Network Layer: Implementing Retrofit/Ktor network calls with Kotlin Coroutines, automatic retry handling, and Room database offline caching.
- Device Quality Assurance: Testing the app across physical hardware devices running Android 5.0 (API 21) up to Android 15 (API 35).
- Release Hardening: Configuring ProGuard code obfuscation, signed Android App Bundles (.aab), and store asset formatting.
- Play Store Publishing Assistance: Uploading production binaries, configuring store listing parameters, and guiding your team through Google Play Console compliance checks.
Shared Collaboration Touchpoints
While responsibilities are distinct, certain milestones require joint collaboration:
- Kick-off Discovery: Aligning on wireframes, data schemas, and edge-case behaviors (e.g., what happens when the user is offline?).
- Intermediate Build Demonstrations: Testing interactive APK previews to confirm navigation flow and visual polish.
- Pre-Launch Sanity Check: Conducting a final end-to-end audit before promoting the build from Play Console Internal Testing to Production.
