How to change webview into Google webview in android 7.1.1

How to change webview into Google webview in android 7.1.1. I have only the android webview option in development mode, not the Google webview.

I was planning to use xposed to replace, but unfortunately it is not valid in android7.11. There may be a change to the android source code.

The following code:

package com.stardust.autojs.xposed.webview;

import android.content.pm.PackageInfo;
import android.content.res.XResources;
import android.os.Build;
import android.webkit.WebView;

import de.robv.android.xposed.IXposedHookZygoteInit;
import de.robv.android.xposed.XC_MethodHook;
import de.robv.android.xposed.XposedBridge;

import static de.robv.android.xposed.XposedHelpers.findAndHookMethod;

/**
 * 替换资源WEBVIEW
 */
public class WebViewReplaceHook implements IXposedHookZygoteInit {

//    public static boolean isReplaceWebView = false;


    @Override
    public void initZygote(StartupParam startupParam) throws Throwable {

//        isReplaceWebView = true;

        try{
            XResources.setSystemWideReplacement("android", "string", "config_webViewPackageName", "com.google.android.webview");
        }catch (Exception e){

        }


        findAndHookMethod("android.webkit.WebViewFactory", null, "getWebViewPackageName", new XC_MethodHook() {
            @Override
            protected void beforeHookedMethod(MethodHookParam param) throws Throwable {
                XposedBridge.log("getWebViewPackageName");
                param.setResult("com.google.android.webview");
            }
        });
    }
}
