I need a complete karaoke experience packaged as a native Android application. At minimum the app must: • display a catalogue of karaoke tracks that users can easily browse and search • play the instrumental track while scrolling the timed lyrics on-screen • let the singer record both audio and video of their performance, saving locally and shareable from within the app • generate a simple score at the end of each song so users can track improvements over time All screens should follow modern Material 3 guidelines and run smoothly on Android 10+. Kotlin is preferred, but Java is acceptable. I will provide the initial batch of instrumental tracks and timed-lyric files; please structure the project so that additional songs can be added later by dropping them into the correct folders or updating a small JSON manifest. Deliverables: 1. Play-store-ready APK and signed AAB 2. Clean, well-commented source code in a private Git repo 3. Brief README explaining how to add new songs, change colours, and rebuild the app 4. A short test video showing the score screen after a sample recording I’ll test on a Pixel 5 and a Samsung A32, so the layout must adapt to different resolutions. If you have previously worked with audio latency issues, please highlight that in your proposal.
