Create a Web View App in Android Studio

Step 1:- Open Android Studio and create a new project.

1. Open Android Studio.
2. Click on “Start a new Android Studio project” or go to File > New > New Project.
3. Choose “Empty Activity” and click “Next”.
4. Name your project, choose a package name, select the language (Java/Kotlin), and set the minimum API level (usually, API 21 or higher is fine). Then click “Finish”.

Step 2: Add the WebView dependency

In your build.gradle file (usually located in the app folder), make sure you have the WebView dependency added. If it’s not there, add it like this:

implementation 'androidx.webkit:webkit:1.4.0'

Step 3: Add Internet Permission

Open your AndroidManifest.xml file from the manifests folder and add the following permission outside the <application> tag:

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

Step 4: Add WebView to the Layout

Open your activity_main.xml file from the res/layout folder. Replace the existing code with the following to create a basic layout with a WebView:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <WebView
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

Step 5: Set Up WebView in MainActivity

Open your MainActivity.java file from the java/com.yourpackage.yourappname/ folder. Replace the existing code with the following to set up the WebView:

package com.yourpackage.yourappname;

import android.os.Bundle;
import android.webkit.WebSettings;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import androidx.appcompat.app.AlertDialog;
import androidx.appcompat.app.AppCompatActivity;

public class MainActivity extends AppCompatActivity {

    private WebView webView;

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

        webView = findViewById(R.id.webview);
        WebSettings webSettings = webView.getSettings();
        webSettings.setJavaScriptEnabled(true); // Enable JavaScript

        webView.setWebViewClient(new WebViewClient());

        // Load initial URL
        loadUrl("https://www.example.com");
    }

    private void loadUrl(String url) {
        if (webView != null) {
            webView.loadUrl(url);
        }
    }

    @Override
    public void onBackPressed() {
        if (webView != null && webView.canGoBack()) {
            webView.goBack();
        } else {
            showExitDialog();
        }
    }

    private void showExitDialog() {
        new AlertDialog.Builder(this)
                .setTitle("Exit App")
                .setMessage("Are you sure you want to exit?")
                .setPositiveButton("Yes", (dialog, which) -> finish())
                .setNegativeButton("No", (dialog, which) -> dialog.dismiss())
                .show();
    }
}
