以下代码（来自最终应用程序的片段）在iOS中运行良好，在Android Pixel 2 Simulator API 33上运行时没有任何错误。

import 'package:just_audio/just_audio.dart';
...
...
class _MyHomePageState extends State<MyHomePage> {
  late final WebViewController controller;

  final AudioPlayer player = AudioPlayer();

 @override
  void initState() {
    super.initState();

    controller = WebViewController()
      ..loadRequest(
        Uri.parse('https://renewfm.org/wp-content/themes/radiostation/showPlaying.php?device=web'),
      );

    //WidgetsBinding.instance.addPostFrameCallback( (_) async {
    //    await player.setUrl('https://renewfm.org/renewfm-stream.php');
    //    await player.play();
    //  }
    //);
    player.setUrl('https://renewfm.org/renewfm-stream.php');
    player.play();
  }
...

iOS开始播放它很好，有或没有WidgetsBinding.instance.addPostFrameCallback代码。Android的Android输出似乎表明它正在尝试播放：

D/BufferPoolAccessor2.0(19617): bufferpool2 0x77d419df0818 : 5(40960 size) total buffers - 1(8192 size) used buffers - 213/218 (recycle/alloc) - 5/432 (fetch/transfer)

但是没有音量。我把模拟器音量控制开了。
这是我的清单：
