Introduction

Android is one of the most popular operating systems for mobiles. In this article, I will show you how to create a Web Browser Android application using Android Studio.
Requirements
Steps to be followed
Follow these steps to create a web Browser Android application using Android Studio. I have included the source code above.
Step 1
Open Android Studio and start a New Android Studio Project.
Android Studio
Step 2
You can choose your application name and choose where your project is stored. If you wish to use C++ for coding the project, mark the "Include C++ support", and click the "Next" button.
Android Studio
Now, select the version of Android and select the target Android devices.
Android Studio
Step 3
Now, add the activity and click the "Next" button.
Android Studio
Add activity name and click "Finish".
Android Studio
Step 4
Go to activity_main.xml, This XML file contains the designing code for the app.
Android Studio
The XML code is given below.
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <android.support.constraint.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3. xmlns:app="http://schemas.android.com/apk/res-auto"
  4. xmlns:tools="http://schemas.android.com/tools"
  5. android:layout_width="match_parent"
  6. android:layout_height="match_parent"
  7. tools:context="abu.webview.MainActivity">
  9. <android.support.v4.widget.SwipeRefreshLayout
  10. android:id="@+id/swipe"
  11. android:layout_width="match_parent"
  12. android:layout_height="match_parent">
  14. <WebView
  15. android:id="@+id/webView"
  16. android:layout_width="match_parent"
  17. android:layout_height="match_parent"/>
  19. </android.support.v4.widget.SwipeRefreshLayout>
  21. </android.support.constraint.ConstraintLayout>
Step 5
We need to make network requests. So, add internet permissions in the AndroidManifest.xml file.
Android Studio
The AndroidManifest.xml code is given below.
  1. <?xml version="1.0" encoding="utf-8"?>
  2. <manifest xmlns:android="http://schemas.android.com/apk/res/android"
  3. package="abu.webview">
  4. <uses-permission android:name="android.permission.INTERNET"/>
  5. <application
  6. android:allowBackup="true"
  7. android:icon="@mipmap/ic_launcher"
  8. android:label="@string/app_name"
  9. android:roundIcon="@mipmap/ic_launcher_round"
  10. android:supportsRtl="true"
  11. android:theme="@style/AppTheme">
  12. <activity android:name=".MainActivity">
  13. <intent-filter>
  14. <action android:name="android.intent.action.MAIN" />
  16. <category android:name="android.intent.category.LAUNCHER" />
  17. </intent-filter>
  18. </activity>
  19. </application>
Step 6
Go to the app, right-click “Directory path”, then click on the path and add a new folder named “Assets” in the main folder. The below template shows how to add an error file. I have attached an error file.

Step 7
Go to Main Activity.java. This Java program is the back-end language for Android.
Android Studio
The Java code is given below.
  1. package abu.webview;
  3. import android.support.v4.widget.SwipeRefreshLayout;
  4. import android.support.v7.app.AppCompatActivity;
  5. import android.os.Bundle;
  6. import android.webkit.WebView;
  7. import android.webkit.WebViewClient;
  9. public class MainActivity extends AppCompatActivity {
  11. WebView webView;
  12. SwipeRefreshLayout swipe;
  14. @Override
  15. protected void onCreate(Bundle savedInstanceState) {
  16. super.onCreate(savedInstanceState);
  17. setContentView(R.layout.activity_main);
  19. swipe = (SwipeRefreshLayout)findViewById(R.id.swipe);
  20. swipe.setOnRefreshListener(new SwipeRefreshLayout.OnRefreshListener() {
  21. @Override
  22. public void onRefresh() {
  23. WebAction();
  24. }
  25. });
  27. WebAction();
  29. }
  32. public void WebAction(){
  34. webView = (WebView) findViewById(R.id.webView);
  35. webView.getSettings().setJavaScriptEnabled(true);
  36. webView.getSettings().setAppCacheEnabled(true);
  37. webView.loadUrl("https://www.google.com/");
  38. swipe.setRefreshing(true);
  39. webView.setWebViewClient(new WebViewClient(){
  41. public void onReceivedError(WebView view, int errorCode, String description, String failingUrl) {
  43. webView.loadUrl("file:///android_assets/error.html");
  45. }
  47. public void onPageFinished(WebView view, String url) {
  48. // do your stuff here
  49. swipe.setRefreshing(false);
  50. }
  52. });
  54. }
  57. @Override
  58. public void onBackPressed(){
  60. if (webView.canGoBack()){
  61. webView.goBack();
  62. }else {
  63. finish();
  64. }
  65. }
  66. }
Step 8
Now, either go to the menu bar and click "Make a project" or press ctrl+f9 to debug the error.
Android Studio
Step 9
Then, click the "Run" button or press shift+f10 to run the project. Select the "virtual machine" option and click OK.
