creating an android project with eclipse
An Android project contains all the files that comprise the source code for your Android app. The Android SDK tools make it easy to start a new Android project with a set of default project directories and files.This lesson shows how to create a new project using Eclipse (with the ADT plugin) .
Create a Project with Eclipse
1) In Eclipse, click New Android App Project in the toolbar. (If you don’t see this button, then you have not installed the ADT plugin—see Installing the Eclipse Plugin.)
2) Fill in the form that appears:

- Application Name is the app name that appears to users. For this project, use "My First App."
- Project Name is the name of your project directory and the name visible in Eclipse.
- Package Name is the package namespace for your app (following the same rules as packages in the Java programming language). Your package name must be unique across all packages installed on the Android system. For this reason, it's generally best if you use a name that begins with the reverse domain name of your organization or publisher entity. For this project, you can use something like "com.example.myfirstapp." However, you cannot publish your app on Google Play using the "com.example" namespace.
- Build SDK is the platform version against which you will compile your app. By default, this is set to the latest version of Android available in your SDK. (It should be Android 4.1 or greater; if you don't have such a version available, you must install one using the SDK Manager). You can still build your app to support older versions, but setting the build target to the latest version allows you to enable new features and optimize your app for a great user experience on the latest devices.
- Minimum Required SDK is the lowest version of Android that your app supports. To support as many devices as possible, you should set this to the lowest version available that allows your app to provide its core feature set. If any feature of your app is possible only on newer versions of Android and it's not critical to the app's core feature set, you can enable the feature only when running on the versions that support it.
Leave this set to the default value for this project.
Click Next.
3) The following screen provides tools to help you create a launcher icon for your app.
You can customize an icon in several ways and the tool generates an icon for all screen densities. Before you publish your app, you should be sure your icon meets the specifications defined in the Iconography design guide.
Click Next.
4) Now you can select an activity template from which to begin building your app.
For this project, select BlankActivity and click Next.
5)Leave all the details for the activity in their default state and click Finish.
Your Android project is now set up with some default files and you’re ready to begin building the app.
