I want to develop an Android Video & Audio Player app with the following features: On app open, a loading image appears and storage & notification permissions are requested. The app has three bottom tabs: Video (shows all device videos with thumbnail & title), Audio (shows all audios with title), and Privacy (lock icon) for private files. A top search bar allows users to search videos & audios by keywords. Each media file has a three-dot menu with options: Play, Move to Private, Delete. Video & audio players allow tap to seek forward/backward, play/pause, volume control, mute/unmute, next/previous media, and a lock icon to lock/unlock the screen. Private files are stored securely in app-private storage, unlocked via PIN/password or optional biometric. Firebase Cloud Messaging integration allows sending notifications with photo, title, and clickable link. Banner-style ads appear after app open (not during media playback) and are clickable. Technical requirements: Kotlin, ExoPlayer for media, MediaStore & SAF for file handling, encrypted storage for private files, Firebase notifications, AdMob banners, clean & responsive UI. Deliverables: Source code + APK, README with build/run instructions, 7-day bugfix support. Budget: ₹10,000–₹15,000. Timeline: 2 weeks.
