+The application dynamically links the unmodified Maven Central artifact
+`org.videolan.android:libvlc-all:3.7.7`. Its Java source JAR and original Maven POM
+are retained here. The binary AAR is fetched by Gradle and is not committed or
+copied into the application source ZIP.

+Rebuild/relink ReelBox with a replacement library by changing the dependency in
+`android/app/build.gradle.kts`, obtaining its corresponding sources, then building
+with a compatible Android SDK/NDK and Flutter toolchain. Sign a
+modified build with your own Android key; the distributed application imposes no
+additional restriction on modified builds. No private release signing key is
+required to rebuild or independently install the application.
+
+Full LGPL-2.1 and attribution notices are in `assets/licenses/` and are included in
+the APK and Flutter's in-app licenses list. ReelBox source is GPL-3.0; native
+components retain their upstream licenses. This is not an official VideoLAN app
+and includes no VideoLAN or KMPlayer branding. The LibVLC binary has not been
+modified. Preserve this file, the original POM and license notices in source
+redistributions.
