我正在关注在Android中播放视频的教程， Tutorial Here

但是当我在模拟器上运行应用程序时，它给了我以下错误

        mediaController.setAnchorView(videoView);
        videoView.setMediaController(mediaController);
        videoView.setVideoURI(video);

        videoView.setOnErrorListener(new OnErrorListener(){

                videoView.start();
            }
        });
    }

    @Override

在此处添加此答案以帮助其他人解决此问题 - 我已经看到此错误主要发生在模拟器上，并且它似乎在设备上运行良好。可能是一个模拟器设置问题，如果我发现任何官方报告的问题，我将更新此线程。如果我尝试播放像wmv这样不受支持的格式，我只会在设备上看到这种情况。如果有人在模拟器上链接到此问题，请添加
