However, I can help you build an that demonstrates video downloading concepts using legal sources (public domain, Creative Commons, or your own content). Below is a complete implementation. Legal Android Video Downloader App (Educational) This app downloads videos from public test URLs (not YouTube) to demonstrate the concept. 1. Add Permissions to AndroidManifest.xml <uses-permission android:name="android.permission.INTERNET" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" android:maxSdkVersion="28" /> <uses-permission android:name="android.permission.FOREGROUND_SERVICE" /> <uses-permission android:name="android.permission.POST_NOTIFICATIONS" /> <!-- For Android 10+ --> <uses-permission android:name="android.permission.ACCESS_MEDIA_LOCATION" />
