However, there are several other standards that should be followed for the android app to be easily extensible. This completes this tutorial on android application development. The following image shows how the android application should look like in the emulator.

Simply run the project as Android app and eclipse would automatically start the emulator (if its not already running), install the application on emulator and start the application’s main activity. Now we can see how it looks by using the ADT plugin to run the application. This completes our basic android application. TextView public class HelloAndroid extends Activity

the following code displays the text Hello, Android in the application’s main activity. The easiest of them all is the Text View which is used to display some text in the activity. As the checkbox suggests, this is optional, but an Activity is almost always used as the basis for an application.Īndroid provides several views to assist developers in the development. It can create a UI if it chooses, but it doesn't need to. An Activity is simply a class that can run and do work. This is a subclass of Android's Activity class. Another thing different from the traditional projects is that android projects have one (ore more) activity. For example, an application that is built against the 2.1 platform library will run normally on an AVD or device that is running the 2.3.3. Android applications are forward-compatible, which means an application will run on the platform against which it is built as well as all platforms that are released in the future. The target you choose here does not have to match the target you chose for your AVD however, the target must be equal to or lower than the target you chose for your AVD. For example, if you choose Android 2.1, your application will be compiled against the Android 2.1 platform library. While the creation of new project, it will ask the version of android that you would like to develop for.

If you can't find the Android project option in the create new project panel, probably you have some error in the installation of ADT plugin. To begin a new project, Go to Eclipse `-> File -> New -> Project ->` Android Project. The ADT plugin creates a template that you require for creating a new android project. Lets begin creating a new android project using eclipse. The Android SDK provides a testing and instrumentation framework to help you set up and run tests within an emulator or device. Test your application with the Testing and Instrumentation framework. See Managing Virtual Devices and Using Hardware Devices for more information. You need to create Android Virtual Devices (AVD) or connect hardware devices on which you will install your applications.

Set up Android Virtual Devices or hardware devices.

The basic steps for developing applications with or without Eclipse are the same: So now, lets start building a small application with android. This is all we need to do to begin developing android applications. The installation instructions for the same can be found here. In addition to this, for developing with eclipse, I also recommend using the ADT pugin. The basic components that you would need to begin development can be found here. It will present you with a window where you can chose the components to download.

Then you can download platforms and other components using the sdk manager.

It would install the SDK manager for android on Windows. If you are sure that you have a JDK, and the installation is still not recognizing the version, try going back and then coming forward again ). To install the Android SDK, run the exe file that you downloaded from the link. I assume that the installation of JDK and Eclipse are pretty straightforward and therefore would skip that. The first step before we can start developing the android app is to obtain Java Development Kit, Eclipse and finally the Android SDK.

Since there are a lot of tutorials for android app development out on the web, I would not be going into too much detail with things that are already available.

Through this post, I will demonstrate the basic process of developing an android application. This post follows the android app development process from the beginning and includes a few FAQs about environment setup, development and debugging.
