Android App Development in Android Studio: Java + Android Edition For Beginners

Book Description

This book covers Android app design fundamentals in Android Studio using Java programming language. The author assumes you have no experience in app development. The book starts with the installation of the required development environment and setting up the emulators. Then, the simplest “Hello World” app is developed step by step. In the next chapter, basics of the Java programming language are given with practical examples. Screenshots and code snippets are clearly given in the book to guide the reader. After the Java lecture, 6 complete Android apps are developed again by step by step instructions.Each code line is explained. As the reader follows the development of the example apps, he/she will learn designing user interfaces, connecting interface objects to code, developing efficient Java code and testing the app on emulators and real devices. The sample apps developed in this book are as follows: 1. Headlight app: Learn the basics of app development and use buttons in your code. 2. Body mass index (BMI) calculator app: Using input boxes, performing calculations and displaying the results on the screen. 3. Simple dice roller app: Using random number generator functions, including images in your project, displaying images on the screen and changing the displayed image programmatically. 4. The compass app: Accessing the magnetic field sensor, setting required permissions, extracting the direction angle and animating a compass figure. 5. Show my location app: Creating a map project, setting required permissions, accessing GPS device and showing real time location on the map. 6. S.O.S. sender app: Adding SMS functionality, setting required permissions and sending real time location using SMS. This book includes 146 figures and 114 code snippets that are used to explain app development concepts clearly. Full resolution colour figures and project files can be viewed and downloaded from the the book’s website: www.android-java.website.

书名：Android Studio中的Android应用程序开发：Java+Android初学者版

本书介绍了Android Studio中使用Java编程语言的Android应用程序设计基础。作者假设您没有应用程序开发经验。本书从安装所需的开发环境和设置仿真器开始。然后，一步一步地开发出最简单的Hello World应用程序。在下一章中，我们将用实际例子介绍Java编程语言的基础知识。书中清楚地给出了截图和代码片段，以指导读者。Java讲座结束后，6个完整的Android应用程序将按照说明逐步重新开发。每行代码都得到了解释。随着读者跟随示例应用程序的开发，他/她将学习设计用户界面、将界面对象连接到代码、开发高效的Java代码以及在模拟器和真实设备上测试应用程序。本书中开发的示例应用程序如下：1.Headlight应用程序：学习应用程序开发的基础知识，并在代码中使用按钮。2.体重指数(BMI)计算器APP：使用输入框，进行计算，并将结果显示在屏幕上。3.简单的掷骰子APP：使用随机数生成器函数，将图像包含在您的项目中，在屏幕上显示图像，并通过编程更改显示的图像。4.指南针应用程序：访问磁场传感器，设置所需的权限，提取方向角，并制作指南针图形动画。5.显示我的位置APP：创建地图项目，设置所需权限，访问GPS设备，在地图上显示实时位置。6.S.O.S.发送者APP：添加短信功能，设置所需权限，使用短信发送实时位置。本书包括146张图和114个代码片段，用于清楚地解释应用程序开发的概念。全分辨率彩色图形和项目文件可以从该书的网站www.android-java.web上查看和下载。
