WebRTC支持

WebRTC****支持

报错：Webcam Error
navigator.mediadevices.getusermedia not present in your browser

解决办法：

// 重新WebChromeClient

public class MWebChromeClient extends WebChromeClient {

    /**

     * 支持WebRTC

     * @param request

     */

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)

    @Override

    public void onPermissionRequest(PermissionRequest request) {

        request.grant(request.getResources());

    }

}

解决办法：

// 重新WebViewClient
public class MWebViewClient extends WebViewClient {
    /**

     * 解决SSL证书错误问题

     * @param view

     * @param handler

     * @param error

     */

    @Override

    public void onReceivedSslError(WebView view, SslErrorHandler handler, SslError error) {

        handler.proceed();

    }

}

总结：动态设置：setWebChromeClient(@Nullable WebChromeClient client)
当H5获取对应权限的时候，会走 onPermissionRequest(PermissionRequest request)回调，
这个时候客户端Check 下有没有该动态权限，如果没有就动态获取权限，然后再调用：
request.grant(request.getResources());
动态给H5授权，这样H5就可以获取到动态的权限，实现对应的功能了
