我的应用程序出现黑屏/冻结错误，我无法解决。所以我做了一个小应用程序，循环播放两个视频，试图重现错误。我成功了。
Android日志中的错误是：

我在互联网上看到的可能是我设置视频的方式，我应该使用SetURI，这有意义吗？
我使用的代码是：
using System;
using Android.App;
using Android.Content;
using Android.Runtime;
using Android.Views;
using Android.Widget;
using Android.OS;
using System.IO;
namespace SimpleVideoPlayer
{
[Activity (Label = "SimpleVideoPlayer", MainLauncher = true)]
public class MainActivity : Activity, Android.Media.MediaPlayer.IOnCompletionListener, Android.Media.MediaPlayer.IOnErrorListener
{
int flag = 1;
string path1 = Path.Combine(Android.OS.Environment.ExternalStorageDirectory.AbsolutePath, "cman/video1.mp4");
string path2 = Path.Combine(Android.OS.Environment.ExternalStorageDirectory.AbsolutePath, "cman/video2.wmv");
VideoView videoView;
protected override void OnCreate (Bundle bundle)
{
base.OnCreate (bundle);
RequestWindowFeature (WindowFeatures.NoTitle);
Window.SetFlags (WindowManagerFlags.Fullscreen, WindowManagerFlags.Fullscreen);
RequestedOrientation = Android.Content.PM.ScreenOrientation.Landscape;
// Set our view from the "main" layout resource
SetContentView (Resource.Layout.Main);
// Get our button from the layout resource,
// and attach an event to it
videoView = FindViewById<VideoView> (Resource.Id.videoView1);
// Seta esta classe como a classe a ser chamada quando o video acabar de ser executado
videoView.SetOnCompletionListener (this);
videoView.SetOnErrorListener (this);
videoView.SetVideoPath (path1);
videoView.Start ();
}
public void OnCompletion (Android.Media.MediaPlayer mp)
{
if (flag == 1) {
videoView.SetVideoPath (path2);
flag = 2;
videoView.Start ();
} else if (flag == 2) {
videoView.SetVideoPath (path1);
flag = 1;
videoView.Start ();
}
}
public bool OnError (Android.Media.MediaPlayer mp, Android.Media.MediaError what, int extra)
{
return true;
}
}
}
布局非常简单：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="25px"
android:minHeight="25px">
<VideoView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/videoView1" />
</LinearLayout>
非常感谢你。

为您的视频对象添加此侦听器
videoView.setOnInfoListener(infoListener);
infoListener将是这样的：
private OnInfoListener infoListener = new OnInfoListener() {
@Override
public boolean onInfo(MediaPlayer mp, int what, int extra) {
if(what==702 && extra == 0 && !mp.isPlaying()){
videoView.stopPlayback();
videoView = null;
// Now reinitialise the videoView and setVideoPath(String) and then start() again
}
return true;
}
};
