<string name="app_name">Hello World</string>
<string name="hello_world">Collaboration Technologies</string>
<string name="action_settings">Settings</string>
</resources>
Running the Application :
Let's try to run our Hello World! application we just created. I assume
you had created your AVD while doing environment setup. To run the
app from Eclipse, open one of your project's activity files and click
Run icon from the toolbar. Eclipse installs the app on your AVD and
starts it and if everything is fine with your setup and application, it
will display the output Emulator window.
