I need a simple Android application whose single mission is to let me run functional, manual tests against the login flow of any build I install. The app should present a clean checklist-style interface where I can: • launch the target APK or activity, • step through predefined login scenarios (valid credentials, invalid password, empty fields, network error, etc.), • capture notes, screenshots and pass/fail status for each step, and • export the results to CSV or share them directly by email. No automation is required; everything happens through on-device interaction so the tester keeps full control. I will provide the exact test cases and acceptance criteria once the framework is in place. Deliverables • Android Studio project (Kotlin or Java) ready to build and sideload • APK for quick installation • Brief README describing how to add or edit test cases and how the results file is structured The job is complete when I can install the APK on a physical device running Android 9+ and reliably record a full set of login-flow results without crashes or data loss.
