推荐答案
的的file：/// android_asset 协议是一个特定的网页视图的事情。那就是：其他系统组件无法读取这些网址。
The file:///android_asset protocol is a WebView-specific thing. That is: other system components can't read those URLs.
的 MediaResourceGetter 不使用的WebView网络堆栈，因此并不理解的file：/// android_asset 的协议。
The MediaResourceGetter doesn't use the WebView's network stack and therefore doesn't "understand" the file:///android_asset protocol.
在您的其他问题，你提到你使用一个本地的HTTP服务器 - 尝试从服务于.MP4
In your other question you mentioned you use a local http server - try serving the .mp4 from that.
