无法在android API 25中的WebView内启动视频 [英] Video is not started inside WebView in android API 25
问题描述
我是android系统的新手，如果我的问题很琐碎，请提前抱歉，但是我找不到任何解决方案.
I'm new to android and sorry in advance if my question is trivial but I was not able to find any solution for it.
我正在处理一个android项目，我有一个WebView，它显示了Assets目录中的网页，我的网页具有如下所示的视频元素
I'm working on an android project and I have a WebView that displays a web page from the assets directory, my web page has a video element as shown below
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<title>video player</title>
</head>
<body>
<video width="400" controls autoplay loop muted>
<source src="./assets/video/video1.webm" type="video/webm">
</video>
</body>
</html>
下面是fragment中负责显示网页的Java代码:
Below is java code from the fragment that is responsible of displaying web page:
mWebView.setWebContentsDebuggingEnabled(true);
mWebView.getSettings().setJavaScriptEnabled(true);
mWebView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
mWebView.getSettings().setMediaPlaybackRequiresUserGesture(false);
mWebView.getSettings().setAllowFileAccess(true);
mWebView.setWebChromeClient(new WebChromeClient());
mWebView.setWebViewClient(new WebViewClient());
mWebView.loadUrl("file:///android_asset/www/video1.html");
我还通过为活动和应用添加android:hardwareAccelerated="true"来修改了AndroidManifest.
I also modified AndroidManifest by adding android:hardwareAccelerated="true" for both activity and application.
当我在具有API级别22的android TV模拟器上测试应用程序时，视频会自动启动，并且视频控件正常工作，但是当我使用具有API级别25的电视模拟器进行测试时，未显示视频，仅显示控件，但视频从未启动无论是通过控件还是自动，都只会显示一个白色块.
When I test application on android TV emulator with API level 22 video start automatically and video controls are working properly, but when I test it using TV emulator with API level 25 video is not displayed only controls are shown but the video never started either from controls or automatically, only a white block is displayed.
编辑1 :添加完整的HTML页面，清单配置和用于显示HTML页面的Java代码.
Edit 1: add full HTML page, manifest configuration and java code for displaying HTML page.
