Webview In Android Project

A Webview is useful when you need increased control over the UI and advanced configuration options that will allow you to embed web pages in a specially-designed environment for your app.

You can add Webview to your app by following simple steps

> create a new android project.

> In the activity_main.xml file add this code for webview and don’t forget to give id to web view.

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:orientation="vertical"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <WebView
    android:layout_marginTop="10dp"
    android:id="@+id/webview"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    </WebView>



</LinearLayout>

After adding the above code you can see the preview of the webview in the design panel in the side.

> In the MainActivity.java file you have to add this code.

package com.example.web_view;

import androidx.appcompat.app.AppCompatActivity;

import android.graphics.Bitmap;
import android.os.Bundle;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;

public class MainActivity extends AppCompatActivity {

    WebView webView;

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

        webView = (WebView)findViewById(R.id.webview);
        webView.loadUrl("https://www.google.co.in");



    }
}

NOTE : webView.loadUrl(“ you can add link of any website you want to load here ");

You can get error when you try to run this code now. As to view a webpage in the browser you new internet connection you also need one here.

So we have to give internet permissions. We can do that in the AndroidManifest.xml file.

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

You can also get CLEAR TEXT NOT PERMITTED ERROR , in that case in the application section of manifest file add :

android:usesCleartextTraffic="true"

Your manifest file should look like this.

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.web_view">
<uses-permission android:name="android.permission.INTERNET"></uses-permission>

    <application
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:usesCleartextTraffic="true"
        android:theme="@style/AppTheme">
        <activity android:name=".MainActivity">
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
    </application>

</manifest>

Now you can run the code and see the output of web view.

Thank You , Happy Coding !
