Make your first application

Android is a very popular operation system for smart phones. That reflects in the rich variety of applications that are made especially for it. The use of the Android operation system and applications is on the rises. We can explain that with the fact that the programming for Android is very simple and is doesn’t require any complex knowledge of programming.
The basis of all good applications is a simple graphical interface. Apple is a great example of the success based on the graphical interface. iPhone has shown that users are not only interested in hardware but also like the interface itself. This shows how important appearance is.

If you want to run your first application in the Android Emulator, you must create an Android Virtual Device (AVD). AVD defines the device settings used by the emulator.
To create an AVD you need to follow these steps:
- Go to Eclipse and select Window -> Android SDK and AVD Manager.
- Select virtual devices in the panel on the left.
- Click New.
- The Create New AVD dialog should appear.
- Type the name of the new AVD. Like “my AVD”.
- Choose a target. (The target is the version of the Android SDK which you want to run on the emulator. We recommend you choose the latest platform that you have installed and ignore the rest.)
- Then you just click on Create AVD.
After you create an AVD you need to go to Eclipse and start your first project. Go to File -> New -> Project. Then you select Android project and click Next. You need to give your project and application a name. Also you will need to choose the platform version that you choose for your AVD. Click Finish and start developing.
If you want to Run and test your application you need to select Run -> Run. Then select Android application.
