NeonCast - Android Kotlin App Template

NeonCast is an enterprise-grade Native Android application template engineered for seamless TV screen mirroring, local media streaming, web video stream sniffing, and smart TV remote control playback. Built with 100% modern Kotlin and Jetpack Compose following MVVM Clean Architecture, this app delivers a smooth, highly responsive DLNA / UPnP TV casting experience optimized for maximum user engagement and monetization.

Whether you are launching a commercial TV streaming app, a smart remote control utility, or a web video stream sniffer application on Google Play, NeonCast provides a sleek neon dark theme UI, robust SSDP networking engine, and production-ready monetization out of the box.

Core Engine & Architecture

• 100% Native Kotlin & Jetpack Compose: Built with the latest Android standards ensuring smooth 60fps UI animations, fast load times, and a reactive component-based user interface.
• SSDP & DLNA/UPnP Discovery Engine: Built-in SSDP M-SEARCH multicast discovery engine for finding Smart TVs (Roku, LG WebOS, Samsung, Sony Bravia, Fire TV, Chromecast DLNA renderers) on local Wi-Fi.
• MVVM Clean Architecture: Professionally structured codebase utilizing Koin for dependency injection. Exceptionally easy to customize, rebrand, and maintain.
• Room Database & Automated Migration: Local SQLite persistence for saving cast history logs, bookmarks, and user preferences offline with `MIGRATION_1_2` support and local JSON backup/restore tools.

App Features for Users

• SSDP Radar TV Scanner & Signal Filter: Auto-scans local Wi-Fi subnets for DLNA / UPnP MediaRenderer devices (Roku, LG WebOS, Samsung Tizen, Sony Bravia, Fire TV, Chromecast) with live RSSI signal strength filtering (Strong/Medium/Weak), device speed test, custom device rename dialog, and manual IP connect.
• Media Hub (Videos, Photos, Audio): Browse device videos with built-in ExoPlayer preview modal and 4K UHD badge, photos with resolution tag & photo slideshow setup launcher, and audio with private listening mode.
• Photo Slideshow Setup Engine: Customize slideshow intervals (3s, 5s, 10s, 15s), transition animations (Fade, Zoom, Slide Right), and background music casting from local audio tracks.
• Web Video Stream Sniffer & Browser: Built-in web browser that automatically detects and extracts M3U8 (HLS), MP4, and DASH (.mpd) video streams from any website for 1-tap TV casting and URL bookmarking.
• TV Remote Control & Haptic Slider: Full-featured TV navigation pad with directional D-Pad (OK, Home, Back, Mute), interactive haptic volume slider, play/pause, seek +/- 10s, and live position progress tracking.
• Private Listening Mode: Route TV audio directly through smartphone headphones without disturbing others in the room.
• Cast History & Bookmarks Manager (with JSON Backup/Restore): Room DB local persistence for logging casted media & saved web video links with 1-tap re-cast and offline JSON backup & restore tools.
• Network Diagnostics & AP Isolation Test: Built-in AP isolation test wizard, router gateway latency ping check, and Wi-Fi signal diagnostic tools.
• Interactive Troubleshooting Guide: Step-by-step connection guide assisting users with router multicast settings, LG/Samsung/Roku pairing, and network troubleshooting.
• In-App Feedback System: Built-in user feedback form with category selection (Bug Report, Feature Request, Connection Issue) and automated email log launcher.
• Multi-Language Support (6 Languages): Pre-translated in English, Bahasa Indonesia, Español, Deutsch, Français, and 日本語 with 1-tap runtime switcher.
• Modern UI/UX Design: Sleek dark neon theme following Material 3 design standards with responsive layouts and 60fps micro-animations.

Monetization & Business Ready

• AdMob Integration: Pre-configured with Google AdMob Adaptive Banner, Interstitial Manager (60s policy capping), Native Advanced Cards, App Open Ads, and UMP GDPR Consent. Unit IDs are securely managed via local.properties.
• Google Play Billing 8.0 Logic: Pre-configured with the latest Google Play Billing Library 8.0 for seamless one-time lifetime upgrade purchases to PRO with non-consumable product verification.

Requirements & Prerequisites

• Android Studio: Android Studio Narwhal Feature Drop 2025.1.2 or Newer.
• Android OS: Minimum Android 8.0 (API level 26), Target API 35 (Android 15).
• Kotlin Knowledge: Basic understanding of Kotlin and Android development.
• AdMob Account: A Google AdMob account if you plan to monetize with ads.

Important Disclosures

• Third-Party Accounts & Fees: Distributing this app on Google Play requires a Google Play Developer account (subject to a one-time registration fee). Google also takes a commission on in-app purchases made via Google Play Billing.
• AdMob Approval: Monetizing with AdMob requires a separate, independent approval process from Google, which is outside the scope of this template purchase.
• Physical Wi-Fi Requirement for Real TV Testing: DLNA SSDP scanning requires a physical Android device connected to the exact same local Wi-Fi router network as the target Smart TV. Emulators operate on virtual NAT interfaces and will not discover physical TVs.
• Keystore Signing Failsafe: Release builds require a valid keystore.properties file to ensure release APKs/AABs are properly signed.
