My Android app is ready for a closed track on Google Play, and I need thorough performance coverage across twelve consecutive days. The single focus is scalability testing—show me how the build behaves as user numbers, data volume, and concurrent sessions climb. You’ll work inside the Google Play Console closed testing flow (I’ll whitelist your accounts) and exercise the app on real Android hardware that spans low-end, mid-range, and high-end devices. Please note each model and OS version you bring to the table so we can correlate results later. Scope of work • Design realistic growth scenarios, gradually increasing simultaneous users, background sync traffic, and data-heavy actions. • Capture CPU, memory, battery, network, ANR, and crash metrics using Android Studio Profiler, Firebase Performance Monitoring, or any comparable tool you already master. • Deliver a short daily report and a comprehensive wrap-up document that flags every bottleneck, includes logcat traces or screen recordings for each reproducible issue, and ranks fixes by severity. Testing starts the moment you accept the Play Console invite. When you bid, confirm the devices you own and the tooling you’ll use so I know you can hit the ground running.
