我无法复制你的例外，但是...

我不认为您可以只传递一个web页面的url，vlc不是WebView--它需要是一个可播放的文件，例如https://jell.yfish.us/media/jellyfish-3-mbps-hd-h264.mkv--并确保在清单中添加internet权限：

<uses-permission android:name="android.permission.INTERNET" />

我还认为，在实例化MediaPlayer之后，需要将布局中的videoView替换为org.videolan.libvlc.util.vlcVideolayout并将其传递到MediaPlayer.attachViews()。

我可以用这些步骤播放视频。

LibVLC也有一个示例项目，在其应用程序级build.gradle文件中，它们指定了jni目录：

android {
...
    sourceSets {
        main {
            jni.srcDirs = [] // Prevent gradle from building native code with ndk; we have our own Makefile for it.
            jniLibs.srcDir 'jni/libs' // Where generated .so files are placed
            assets.srcDirs = ['src/main/assets', '../assets/']
        }
    }
}
