Android's user interface is mainly based on direct manipulation, using touch gestures that loosely correspond to real-world actions, such as swiping, tapping and pinching, to manipulate on-screen objects along with a virtual key board for text input In addition to touchscreen devices, Google has further developed Android Tv for televisions, Android Auto for cars, and android Wear for wrist watches, each with a specialized user interface. Variants of Android are also used on notebooks, game consoles, digital cameras, and other electronics Android has the largest installed base of all operating systems of any kind. Android has been the best selling Os on tablets since 2013,andonsmartphonesitisdominantbyanymetric(soUrce:https://en.wikipediaorg/wiki/android_(operatinG_system)) In this ebook, we provide a compilation of android programming examples that will help you kick-start your own web projects We cover a wide range of topics, from Services and Views, to Google Maps and Bluetooth functionality. With our straightforward tutorials, you will be able to get your own projects up and running in minimum time Android Programming cookbook About the author Chryssa is a Computer Science graduate from Athens University of Economic and Business.

She has worked as a junior Software Engineer in the telecommunications area and currently works as an Android developer. Android Programming cookbook 1/143 Chapter 1 Android Tutorial For Beginners There are lots of reasons why more and more people are interested in learing how to be able to develop Android applications Unarguably, Android is the most popular mobile operating system, with almost 2 billion devices activated and it offers a unified approach to application development for mobile devices That means, that developers need only develop for Android, and their applications will be able to ruin on different devices powered by android. This particular asset gives Android endless possibilites! This means that and application that is designed to work on mobile phone devices can be also transfered to android powered TV sets or Android Car systems This is why, Android is an exciting space to make apps that can help you in every aspect of your life, can help you communicate, organize, educate, entertain or just to make your life casier in every device that they might run on In this special example, we are going to set our Android Development Studio IDE, make our very first Android application and discover the Android Development world in the easiest possible way The mobile development world can be very fun, because the direct results we see when creating our own application, can be highly motivating and rewarding 1.1 What is android? Android is a mobile operating system currently developed by Google, based on the linux kernel and designed primarily for touchscreen mobile devices such as smartphones and tablets. And as we said before, Android offers a unified approach to application development for mobile devices Android is an open-source operating system named Android. Google has made the code for all the low-level"stuff"as well as the needed middleware to power and use an electronic device and gave android freely to anyone who wants to write code and build the operating system from it. There is even a full application framework included, so third-party apps can be built and installed then made available for the user to run as they like The "proper"name for this is the Android Open Source Project, and this is w hat people mean when they say things like android is open and free. Android, in this iteration, is free for anyone to use as they like 1.2 Installing android studio In order to write an Android application, we are going to need a development environment. Google has made a very useful tool for all Android Developers, the Android Studio. Android Studio is the official IDE for Android development, and with a single download includes everything you need to begin developing Android apps. Included in the download kit, are the Software Development Kit (SDK), with all the Android libraries we may need, and the infrastructure to download the many Android emulator instances, so that we can initially run our application, without needing a real device So, we are going to download and install Android Studio Android Programming cookbook 2/143 First we have to have installed the Java Development Kit (DK) from Oracle. If you do not, please you should download the latest JDK from the Oracles special section here L Android Studio 2.1.2 Android Studio Android studio 62 8A EVE TRs Figure 1.1: Android Studio Installation-step I
