Question

我是Android开发和混合移动应用程序的新手，但我需要在混合移动应用程序中播放视频。我正在使用HTML5原生视频标签，我可以确认它在IOS上运行良好。

Android手机上发生的情况是当您按下播放按钮时，屏幕左侧空白，我可以在日志中看到以下几行：

我查看了stackoverflow.com并阅读了所有评论和建议，

设置WebChrome客户端和
在AndroidManifest.xml中启用硬件加速器

<?xml version='1.0' encoding='utf-8'?>
<manifest android:hardwareAccelerated="true" android:versionCode="30306" android:versionName="3.3.6" android:windowSoftInputMode="adjustPan" package="com.example" xmlns:android="http://schemas.android.com/apk/res/android">
    <supports-screens android:anyDensity="true" android:largeScreens="true" android:normalScreens="true" android:resizeable="true" android:smallScreens="true" android:xlargeScreens="true" />
    <uses-permission android:name="android.permission.INTERNET" />
    <uses-permission android:name="android.permission.CALL_PHONE" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" />
    <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
    <uses-sdk android:minSdkVersion="16" android:targetSdkVersion="23" />
    <application android:allowBackup="false" android:hardwareAccelerated="true" android:icon="@drawable/icon" android:label="@string/app_name" android:name="com.example.MyApplication">
        ... 
        ...
        ...
    </application>
</manifest>

我还检查了视频的内容类型和大小（1MB）：

http GET https://s3-ap-southeast-2.amazonaws.com/demovideos/video.mp4

HTTP/1.1 200 OK
Accept-Ranges: bytes
Content-Length: 1065903
Content-Type: video/mp4

节点： - 该应用程序使用HTML5编写，并使用PhoneGAP Wrapped。

如果你能告诉我为什么它不起作用，我真的很感激。请不要发送Stackoverflow链接，我已经尝试过所有这些链接。

提前多多感谢。

如果您尝试在模拟器上使用视频标记，我们发现存在问题。 Android版本的视频拍摄也存在问题=＆lt; 4.4.2

Answer 2

感谢您的帮助，我们发现有人通过调用代码来禁用代码中的硬件加密：

this.setLayerType（View.LAYER_TYPE_SOFTWARE，null）;
