Android Programming for Beginners

Learn all the Java and Android skills you need to start making powerful mobile applications

Android Programming for Beginners

About This Book

• Kick-start your Android programming career, or just have fun publishing apps to the Google Play marketplace
• A first-principles introduction to Java, via Android, which means youll be able to start building your own applications from scratch
• Learn by example and build three real-world apps and over 40 mini apps throughout the book

Who This Book Is For
Are you trying to start a career in programming, but havent found the right way in? Do you have a great idea for an app, but dont know how to make it a reality? Or maybe youre just frustrated that "to learn Android, you must know Android." If so, Android Programming for Beginners is for you. You dont need any programming experience to follow along with this book, just a computer and a sense of adventure.

What You Will Learn

• Master the fundamentals of coding Java for Android
• Install and set up your Android development environment
• Build functional user interfaces with the Android Studio visual designer
• Add user interaction, data captures, sound, and animation to your apps
• Manage your apps data using the built-in Android SQLite database
• Find out about the design patterns used by professionals to make top-grade applications
• Build, deploy, and publish real Android applications to the Google Play marketplace

In Detail
Android is the most popular OS in the world. There are millions of devices accessing tens of thousands of applications. It is many peoples entry point into the world of technology; it is an operating system for everyone. Despite this, the entry-fee to actually make Android applications is usually a computer science degree, or five years worth of Java experience.

Android Programming for Beginners will be your companion to create Android applications from scratch-whether youre looking to start your programming career, make an application for work, be reintroduced to mobile development, or are just looking to program for fun. We will introduce you to all the fundamental concepts of programming in an Android context, from the Java basics to working with the Android API. All examples are created from within Android Studio, the official Android development environment that helps supercharge your application development process.

After this crash-course, well dive deeper into Android programming and youll learn how to create applications with a professional-standard UI through fragments, make location-aware apps with Google Maps integration, and store your users data with SQLite. In addition, youll see how to make your apps multilingual, capture images from a devices camera, and work with graphics, sound, and animations too.

By the end of this book, youll be ready to start building your own custom applications in Android and Java.

OpenCV Android Programming By Example

Develop vision-aware and intelligent Android applications with the robust OpenCV library

OpenCV Android Programming By Example
About This Book

• This is the most up-to-date book on OpenCV Android programming on the market at the moment. There is no direct competition for our title.
• Based on a technology that is increasing in popularity, proven by activity in forums related to this topic.
• This book uniquely covers applications such as the Panoramic viewer and Automatic Selfie, among others.

Who This Book Is For
If you are an Android developer and want to know how to implement vision-aware applications using OpenCV, then this book is definitely for you.

It would be very helpful if you understand the basics of image processing and computer vision, but no prior experience is required

What You Will Learn

• Identify and install all the elements needed to start building vision-aware Android applications
• Explore image representation, colored and gray scale
• Recognize and apply convolution operations and filtering to deal with noisy data
• Use different shape analysis techniques
• Extract and identify interest points in an image
• Understand and perform object detection
• Run native computer vision algorithms and gain performance boosts

In Detail
Starting from the basics of computer vision and OpenCV, well take you all the way to creating exciting applications. You will discover that, though computer vision is a challenging subject, the ideas and algorithms used are simple and intuitive, and you will appreciate the abstraction layer that OpenCV uses to do the heavy lifting for you. Packed with many examples, the book will help you understand the main data structures used within OpenCV, and how you can use them to gain performance boosts. Next we will discuss and use several image processing algorithms such as histogram equalization, filters, and color space conversion. You then will learn about image gradients and how they are used in many shape analysis techniques such as edge detection, Hough Line Transform, and Hough Circle Transform. In addition to using shape analysis to find things in images, you will learn how to describe objects in images in a more robust way using different feature detectors and descriptors.

By the end of this book, you will be able to make intelligent decisions using the famous Adaboost learning algorithm.

Style and approach
An easy-to-follow tutorial packed with hands-on examples. Each topic is explained and placed in context, and the book supplies full details of the concepts used for added proficiency.
