Three finished Android apps are ready for their final enhancement: integrating a hosting layer so user data and media can live on a reliable back-end instead of locally on the device. All UI assets, icons, and existing source code are packaged and waiting in the repository; the work now is purely feature addition, not bug fixing or UI tweaks. Scope of work • Choose or configure a hosting solution (Firebase, AWS, or any lightweight VPS—whichever fits best). • Wire the back-end to each app so login, uploads, and simple read/write actions pass through tested API calls. • Update the project settings, build files, and pro-guard rules where needed. • Provide clear build instructions and a short “read-me” detailing endpoints, keys, and deployment steps. Acceptance criteria • All three apps compile and run on the latest Android release without crashes. • Remote storage and retrieval succeed in emulator and at least one physical device test. • Source code, updated assets, and documentation are delivered in a single pull request or zipped folder. • The total effort can be broken into two milestones; I’ll distribute roughly USD 100 across them once each step is approved. No additional features such as in-app purchases, push notifications, or social media integration are planned for this phase, so focus stays entirely on a clean, lightweight hosting implementation.
