Change from CordovaWebView to SystemWebView in latest Cordova not working

I stuck in my old version Android App based on Codova
I updated My Android App to latest version android@7.0.0

Now where i used CordovaWebView for for Webview in my app as follows

<org.apache.cordova.CordovaWebView
         android:id="@+id/cordovaWebCallWebView"
         android:layout_width="match_parent"
         android:layout_height="match_parent" />

but it’s not present in latest version of Cordova. So I changed to it by below lines

 <org.apache.cordova.engine.SystemWebView
 android:id="@+id/SystemWebView"
 android:layout_width="match_parent"
 android:layout_height="match_parent" />

where i am using WebRtc for my App So I used following method of SystemWebView Class

cwv.setWebChromeClient(new WebChromeClient() {

            @Override
            public void onPermissionRequest(final PermissionRequest request) { 
                javaToJavascript.webrtcCallLog("web.java", "permission asked is"+Arrays.deepToString(request.getResources()),0); //This logs the type of permission asked
                Log.i("The list of permission asked is ", Arrays.deepToString(request.getResources())); // this askes for android.webkit.resource.AUDIO_CAPTURE permission

                getActivity().runOnUiThread(new Runnable() {
                    @TargetApi(Build.VERSION_CODES.LOLLIPOP)
                    @Override
                    public void run() {
                        Log.i("Value Of the permission asked is ", request
                                .getOrigin().toString());

                        request.grant(request.getResources());

                    }
                });

            }
        });

Now i got runtime error in my Main java file regarding classCastException

java.lang.RuntimeException: Unable to start activity ComponentInfo{com.simCard.web/com.simCard.web.WebCall}: java.lang.ClassCastException: com.simCard.web.WebCall$1 cannot be cast to org.apache.cordova.engine.SystemWebChromeClient
