Android Studio 4.1 Development Essentials – Java Edition

By: Neil Smyth

Overview of this book

For developers, Android 11 has a ton of new capabilities. The goal of this book is to teach the skills necessary to develop Android-based applications using the Java programming language. This book begins with the steps necessary to set up an Android development and testing environment. An overview of Android Studio along with the architecture of Android is covered next, followed by an in-depth look at the design of Android applications and user interfaces using the Android Studio environment. You will also learn about the Android architecture components along with some advanced topics such as touch screen handling, gesture recognition, the recording and playback of audio, app links, dynamic delivery, the AndroidStudio profiler, Gradle build configuration, and submitting apps to the Google Play Developer Console. The concepts of material design, including the use of floating action buttons, Snackbars, tabbed interfaces, card views, navigation drawers, and collapsing toolbars are a highlight of this book. This edition of the book also covers printing, transitions, and cloud-based file storage; the foldable device support is the cherry on the cake. By the end of this course, you will be able to develop Android 11 Apps using Android Studio 4.1, Java, and Android Jetpack.

55.2 Creating the Implicit Intent

As outlined above, the implicit intent will be created and issued from within a method named showWebPage() which, in turn, needs to be implemented in the MainActivity class, the code for which resides in the MainActivity.java source file. Locate this file in the Project tool window and double-click on it to load it into an editing pane. Once loaded, modify the code to add the showWebPage() method together with a few requisite imports:

package com.ebookfrenzy.implicitintent;

 

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import android.net.Uri;

import android.content.Intent;

import android.view.View;

 

public class MainActivity extends AppCompatActivity {

 

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);
