Question

我目前正在开发一款Android应用程序，其中包括一个视频播放器，它使用Android的VideoView通过HTTP加载mp4视频文件。它适用于安装了Android 5.1.1的Nexus 4以及安装了Android 4.4的平板电脑。

但是，使用Android 6.0后，视频流会在几分钟后意外终止（在Nexus 5和仿真器上测试）。正如您在日志输出中看到的那样，流将播放约5分钟，直到发生java.net.ProtocolException ，另外1分钟播放缓冲区为空。

添加唤醒和wifi锁似乎并没有阻止这种行为。

以下是视频播放器片段的布局配置：

<?xml version="1.0" encoding="utf-8"?>
<FrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".VideoActivity"
    android:keepScreenOn="true">

<VideoView
    android:id="@+id/video"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_gravity="center"
    />

    ...

部分代码：

videoView = (VideoView) v.findViewById(R.id.video);
videoView.setOnCompletionListener(this);
videoView.setOnPreparedListener(this);
videoView.setVideoURI(videoUrl);
videoView.seekTo(0);
videoView.start();

Android MediaPlayer Http流的mp4文件在几分钟后导致“Unexcepted end of stream”，仅在Android 6（M）上
