Android App Development Essentials: Create Your First App
Explore the world of Android app development. This training course prepares you to create your very first Android app—helping you understand the technologies at work and prepare your computer for development and testing. Learn how to configure Android Studio, the Android SDK, and emulator software, and study the different files in a typical Android app: build scripts, the app manifest file, permissions tags, and icons. Finally, learn how an app is built from the bottom up, with screens, activities, and layouts. David Gassner shows how to define the visual presentation with XML and widgets, and control the logic with Java code. This simple overview is designed to provide you with everything you need to know to understand the Android development process. Later courses in the Essentials series concentrate on the specific skills you need to master.

Topics include:
- Installing Android Studio
- Creating your first Android Studio project
- Managing profile files, including Gradle scripts and support libraries
- Defining screens with activities
- Implementing designs in XML layouts

Android App Development Essentials: Local Data Storage
Android developers who need to manage and present data have many tools available to them in the application framework of Android. This course covers a variety of data persistence techniques, including storing data in shared preferences—key-value pairs—in JSON-formatted text files, and in relational databases with SQLite. Join David Gassner as he demonstrates these data management techniques. He also explains how to use relevant design patterns to model data with Java classes, and how to present data to the user with the Android SDK's ListView and RecyclerView components.

Topics include:
- Modeling data in POJO classes
- Customizing a ListView item display
- Displaying data in a RecyclerView
- Creating a custom array adapter
- Managing shared preferences with Java
- Creating and importing JSON data files
- Accessing SQLite from the command line
- Retrieving data with SQLite queries

Android App Development Essentials: Distributing Apps
Once you've created an Android app, it's time to share it with the world. Luckily, there are many avenues to distribution. This course focuses on the two primary channels: Google Play and the Amazon Appstore. The first step is to prepare your app, including cleaning up, minifying, and (optionally) obfuscating code to prevent others from decompiling and stealing it. Then you'll learn how to package and export an APK file for distribution. Author David Gassner then walks you through each step involved in releasing an app through Google Play or Amazon, including creating graphics and marketing copy, setting pricing, registering for developer programs, uploading the APK, and publishing the app. Finally, once your app is released, learn how to track its success with the built-in reporting features offered by both stores.

Topics include:
- Packaging apps in APK files
- Building a signed APK file
- Distributing through Google Play
- Adding app graphics
- Setting pricing
- Publishing the app
- Submitting an app to Amazon
- Tracking app use in Google Play and Amazon
