Android Application Development Cookbook - Second Edition

Overview of this book

The Android OS has the largest installation base of any operating system in the world; there has never been a better time to learn Android development to write your own applications, or to make your own contributions to the open source community! This “cookbook” will make it easy for you to jump to a topic of interest and get what you need to implement the feature in your own application. If you are new to Android and learn best by “doing,” then this book will provide many topics of interest. Starting with the basics of Android development, we move on to more advanced concepts, and we’ll guide you through common tasks developers struggle to solve. The first few chapters cover the basics including Activities, Layouts, Widgets, and the Menu. From there, we cover fragments and data storage (including SQLite), device sensors, the camera, and GPS. Then we move on more advanced topics such as graphics and animation (including OpenGL), multi-threading with AsyncTask, and Internet functionality with Volley. We’ll also demonstrate Google Maps and Google Cloud Messaging (also known as Push Notifications) using the Google API Library. Finally, we’ll take a look at several online services designed especially for Android development. Take your application big-time with full Internet web services without having to become a server admin by leveraging the power of Backend as a Service (BaaS) providers.

  • Transition-based animation: Animation based on starting and ending property change

  • Built-in animations: Some common transition effects, such as fade-in/out and movement

  • Resource file support: Save animation values to a resource (XML) file to load during runtime

  • Lifecycle callbacks: Receive callback notifications during the animation

A transition animation consists of the following:

  • Starting Scene: The view (or ViewGroup) at the start of the animation

  • Transition: The change type (see later on)

  • Ending Scene: The ending view (or ViewGroup)

  • Transitions: Android provides built-in support for the following three transitions:

    • AutoTransition (default transition): Fade out, move, and resize, then fade in (in that order)

    • Fade: Fade in, fade out (default), or both (specify order)

    • ChangeBounds: Move and resize
