Chromium WebView 中的 WebRTC 错误:“CheckMediaAccessPermission:不支持" [英] WebRTC error inside Chromium WebView: "CheckMediaAccessPermission: Not supported"

问题描述

我正在尝试在 WebView 中显示 WebRTC 聊天.根据本文档，WebView v36 支持WebRTC.对于我的测试，我使用的是带有 Chrome/39.0.0.0 的设备，并且我已经为 AndroidManifest.xml 文件添加了权限:

I'm trying to show WebRTC chat in WebView. According to this documentation, WebView v36 supports WebRTC. For my test I'm using a device with Chrome/39.0.0.0 and I have added permissions to the AndroidManifest.xml file:

<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.CAMERA" />
<uses-permission android:name="android.permission.RECORD_AUDIO" />
<user-permission android:name="android.permission.MODIFY_AUDIO_SETTINGS" />

但是当我进入聊天时，我看到一个 Chromium 错误日志(设备不显示\翻译任何内容，只有加载"进度条):

but when I enter into the chat, I see a Chromium error log (device doesn't show \ translate anything, only 'loading' progress bar):

W/AudioManagerAndroid: Requires MODIFY_AUDIO_SETTINGS and RECORD_AUDIO
W/AudioManagerAndroid: No audio device will be available for recording
E/chromium: [ERROR:web_contents_delegate.cc(178)] WebContentsDelegate::CheckMediaAccessPermission: Not supported.
E/chromium: [ERROR:web_contents_delegate.cc(178)] WebContentsDelegate::CheckMediaAccessPermission: Not supported.
W/AudioManagerAndroid: Requires MODIFY_AUDIO_SETTINGS and RECORD_AUDIO
W/AudioManagerAndroid: No audio device will be available for recording
D/ChromiumCameraInfo: Camera enumerated: front

在真实设备上测试，Android 5.1.1.

Tested on a real device, Android 5.1.1.

推荐答案

需要额外的权限请求

webView.setWebChromeClient(new WebChromeClient(){
        @TargetApi(Build.VERSION_CODES.LOLLIPOP)
        @Override
        public void onPermissionRequest(final PermissionRequest request) {
                request.grant(request.getResources());
        }
    });

更新但它不适用于音频捕获
