1. Now Copy and paste the following codes into your WebView App. (MainActivity.java)

//improve WebView Performance
myWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
myWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
myWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webSettings.setDomStorageEnabled(true);
webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
webSettings.setUseWideViewPort(true);
webSettings.setSavePassword(true);
webSettings.setSaveFormData(true);
webSettings.setEnableSmoothTransition(true);

2. Now Open Your AndroidMainfest.xml file and add the following code under MainActivity.

android:hardwareAccelerated="true"

Here are the full codes…

MainActivity.java

package com.techedutricks.techedutricks;

import androidx.appcompat.app.AppCompatActivity;

import android.annotation.SuppressLint;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

private WebView myWebView;

@SuppressLint("SetJavaScriptEnabled")
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

myWebView = (WebView) findViewById(R.id.webview);
WebSettings webSettings=myWebView.getSettings();
webSettings.setJavaScriptEnabled(true);

//improve WebView Performance
myWebView.getSettings().setRenderPriority(WebSettings.RenderPriority.HIGH);
myWebView.getSettings().setCacheMode(WebSettings.LOAD_CACHE_ELSE_NETWORK);
myWebView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);
webSettings.setDomStorageEnabled(true);
webSettings.setLayoutAlgorithm(WebSettings.LayoutAlgorithm.NARROW_COLUMNS);
webSettings.setUseWideViewPort(true);
webSettings.setSavePassword(true);
webSettings.setSaveFormData(true);
webSettings.setEnableSmoothTransition(true);

//Load Website
myWebView.loadUrl("https://www.google.com");
myWebView.setWebViewClient(new WebViewClient());
}

public void onBackPressed(){
if (myWebView.canGoBack())
{
myWebView.goBack();
}
else {
super.onBackPressed();
}
}
}

AndroidMainfest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.techedutricks.techedutricks">

<uses-permission android:name="android.permission.INTERNET" />

<application

android:theme="@style/Theme.TechEduTricks">

<activity android:name=".MainActivity"
android:hardwareAccelerated="true"
>

</activity>
<activity android:name=".WelcomeScreen">
