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.

Introduction


How can we detect whether there will be any performance issues with our app? What are the common problems in Android apps? And how can we fix these issues?

When it comes to performance, a few problems that could occur are as follows:

  • Memory leaks: Although Android comes with its own memory management system, memory leaks may occur.

  • Out of memory exceptions: Your app could easily run out of memory, resulting in a crash of your app. For example, think of processing large images on low-end devices.

  • Overdraw: Overdraw is the phenomenon of a pixel on a view being drawn more than once. It can result in an unresponsive or laggy user interface.

In the upcoming recipes, we will examine the problems listed here. The Android SDK and Android Studio come with some great tools to examine your app.
