Hello, World. 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.
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.

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. So today, I’m pleased to announce the release of a licensing service for applications in Android Market. This simple and free service provides a secure mechanism to manage access to all Android Market paid applications targeting Android 1.5 or higher. At run time, with the inclusion of a set of libraries provided by us, your application can query the Android Market licensing server to determine the license status of your users.
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 (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. Eclipse Downloads. SDK Download. Before installing Android Studio or the standalone SDK tools, you must agree to the following terms and conditions.
