Overview of this book

This book starts with an introduction of Android Studio and why you should use this IDE rather than Eclipse. Moving ahead, it teaches you to build a simple app that requires no backend setup but uses Google Cloud or Parse instead. After that, you will learn how to create an Android app that can send and receive text and images using Google Cloud or Parse as a backend. It explains the concepts of Material design and how to apply them to an Android app. Also, it shows you how to build an app that runs on an Android wear device. Later, it explains how to build an app that takes advantage of the latest Android SDK while still supporting older Android versions. It also demonstrates how the performance of an app can be improved and how memory management tools that come with the Android Studio IDE can help you achieve this. By the end of the book, you will be able to develop high quality apps with a minimum amount of effort using the Android Studio IDE.

Chapter 7. Content Providers and Observers

In most apps, we need to persist data and often use SQLite for this purpose.

A very common situation is that of the list and detail views. By using content providers, we do not just provide a way of communication between apps but also save ourselves much work in our own app.

In this chapter, you will learn about:

  • Content providers

  • Consuming and updating data using a content provider

  • Changing projections to display Key Performance Indicators (KPIs) in your app

  • Communicating with other apps using content providers
