title: WebRTC error inside Chromium WebView: "CheckMediaAccessPermission: Not supported"
body: <p>I'm trying to show <code>WebRTC</code> chat in <code>WebView</code>.
  According to <a href="https://developer.chrome.com/multidevice/webview/overview" rel="nofollow noreferrer">this documentation</a>, <code>WebView v36</code> supports <code>WebRTC</code>. For my test I'm using a device with <code>Chrome/39.0.0.0</code> and I have added permissions to the <code>AndroidManifest.xml</code> file:</p>
  <pre class="lang-xml prettyprint-override"><code>&lt;uses-permission android:name=&quot;android.permission.INTERNET&quot; /&gt;
  &lt;uses-permission android:name=&quot;android.permission.CAMERA&quot; /&gt;
  &lt;uses-permission android:name=&quot;android.permission.RECORD_AUDIO&quot; /&gt;
  &lt;user-permission android:name=&quot;android.permission.MODIFY_AUDIO_SETTINGS&quot; /&gt;
  </code></pre>
  <p>but when I enter into the chat, I see a Chromium error log <em>(device doesn't show \ translate anything, only 'loading' progress bar)</em>:</p>
  <pre><code>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.
