I already run a PHP backend that issues JWT tokens and answers to POST requests. What I now need is a native Android application that authenticates with those tokens, sends the necessary POST calls, and then turns the JSON responses into a clean on-device experience. Core flow • The app signs in, receives the JWT, and transparently refreshes it whenever required. • Depending on the current token the interface must switch between three roles—Admin, Regular user, and Guest user—unlocking or hiding features accordingly. • Returned payloads include text blocks, images, and occasional data arrays that must be rendered as simple charts/graphs. What I expect as a deliverable 1. Full Android Studio project (Kotlin or Java) compiling without paid libraries. 2. Network layer that cleanly handles all POST requests (Retrofit/OkHttp or equivalent). 3. Reusable UI components for text, image galleries, and lightweight chart views. 4. Basic role-based navigation demonstrating how each user type sees different content. 5. Clear README explaining build steps and where to point the base URL for my server. When I can install the APK, sign in, browse data, and see the role switching in action, the job is done.

Hello! I can build the native Android application that integrates with your PHP backend, handles JWT authentication, and delivers a clean, role-based user experience. Here's how I can help: * Develop the Android Studio project in Kotlin, implementing a Retrofit/OkHttp network layer for secure POST calls and JWT management with transparent refresh. * Build reusable UI components to display text blocks, image galleries, and render simple charts from JSON array data. * Implement a clear navigation structure that switches dynamically between Admin, Regular, and Guest user interfaces based on the token's role. * Deliver a fully functional APK with a clear README for setup, including instructions for connecting to your server's base URL. To ensure the role logic aligns perfectly, could you share a sample of the JWT payload or the specific claim that defines the user role (e.g., `"role": "admin"`)? I'm ready to start development immediately.

Understood, the requirements are clear. The project scope aligns with what I’m looking for: finalizing the communication bridge between the mobile app and the ESP32, then routing text output through the ChatGPT API and returning it as a clean text-to-speech response. I’m interested in moving forward. Please share the GitHub repository link along with access, and provide the sample prompts that will be used. The expected end result is aligned: the ESP32 can be flashed with the finalized firmware, the Flutter app runs properly, prompts can be sent, and the spoken (TTS) response is played back successfully. Looking forward to the repository link and next details. Thank you.
