Hello, World. Welcome to Android application development!

Hello, World

This class teaches you how to build your first Android app. You’ll learn how to create an Android project and run a debuggable version of the app. You'll also learn some fundamentals of Android app design, including how to build a simple user interface and handle user input. Set Up Your Environment Before you start this class, be sure you have your development environment set up. Note: Although most of this training class expects that you're using Android Studio, some procedures include alternative instructions for using the SDK tools from the command line instead. Projects for Android. Notepad Tutorial. This tutorial on writing a notepad application gives you a "hands-on" introduction to the Android framework and the tools you use to build applications on it.

Notepad Tutorial

Starting from a preconfigured project file, it guides you through the process of developing a simple notepad application and provides concrete examples of how to set up the project, develop the application logic and user interface, and then compile and run the application. The tutorial presents the application development as a set of exercises (see below), each consisting of several steps. You should follow the steps in each exercise to gradually build and refine your application. The exercises explain each step in detail and provide all the sample code you need to complete the application.

When you are finished with the tutorial, you will have created a functioning Android application and will have learned many of the most important concepts in Android development. Who Should Use this Tutorial. Package Index. API Reference. Developer's Guide. Android provides a rich application framework that allows you to build innovative apps and games for mobile devices in a Java language environment.

Developer's Guide

The documents listed in the left navigation provide details about how to build apps using Android's various APIs. If you're new to Android development, it's important that you understand the following fundamental concepts about the Android app framework: Apps provide multiple entry points Android apps are built as a combination of distinct components that can be invoked individually.

For instance, an individual activity provides a single screen for a user interface, and a service independently performs work in the background. From one component you can start another component using an intent. Learn more: Just speak it: introducing Voice Actions for Android. Our mobile phones have become modern-day Swiss Army knives. An Android phone is a handheld computer, a music player, a notepad, a GPS navigation unit and more, all rolled into one sleek device that fits in your pocket. Today’s phones do so many things for us that sometimes we don’t even think about how we do them. Even though our phones do all these new things, the most natural way of interacting with a phone remains what it always has been: speaking. And to that end, we’re pleased to introduce Voice Actions for Android. Voice Actions are a series of spoken commands that let you control your phone using your voice. To use Voice Actions, tap the microphone button on the Google search box on your home screen, or press down for a few seconds on the physical search button on your phone to activate the “Speak Now” screen.

Speak any of these commands to perform a Voice Action on your phone: And of course, you can still conduct a Google search using your voice. Google Chrome Blog. Licensing Service For Android Applications. [This post is by Eric Chu, Android Developer Ecosystem. — Tim Bray] In my conversations with Android developers, I often hear that you’d like better protection against unauthorized use of your applications.

Android Cloud To Device Messaging. [This post is by Wei Huang, who helped implement this feature. — Tim Bray] In the just-launched Android 2.2, we’ve added a new service to help developers send data from servers to their applications on Android phones.

Android Cloud To Device Messaging

Android Cloud to Device Messaging (C2DM) makes it easier for mobile applications to sync data with servers. Most of the useful applications on your mobile phone use the Internet to keep users connected. Traditionally, many apps use polling to fetch data periodically. POP mail clients, for example, connect to the server every 15 minutes or so. Having the server push messages to the client asynchronously may be a superior choice for getting the latest data to your applications, resulting in fresher data and more efficient use of the network and your battery. Many of the Google applications on Android already use push to keep their data fresh, for example Gmail, Contacts, and Calendar. Here are a few basic things to know about C2DM: Developers Home.
