I have an existing Android app that is stable but still very lean on features. The immediate goal is two-fold: first, roll out a new “upload” capability inside the app (users need to be able to select a file—primarily images or PDFs—from local storage and send it securely to our backend); second, compile, sign, and publish the updated build to the Google Play Console so the change is live for all users. The current stack is Kotlin with standard Android Jetpack libraries; the backend is ready and exposes a REST endpoint for the upload, so the mobile side only needs to handle file selection, progress indication, and a simple success/fail response. If you prefer Java that’s fine—as long as the final APK/AAB plays nicely with our existing codebase. Deliverables • Updated versionCode / versionName and release notes prepared in the Play Console
