8) Write the steps of connecting your android device to Eclipse.

Connecting Your Android Device to Eclipse:

1. Before we start, you must enable debugging mode on your Android device. Open the 'Applications' folder and select 'Development.' On the subsequent screen, ensure the 'USB Debugging' checkbox is ticked.

2. If you're developing on Windows, you'll need to install the USB driver for your device. Your first stop should be the list of OEM USB Drivers maintained by Google.

3. Connect the device to your computer using the appropriate USB cable.

4. Inside your Eclipse installation, open the 'Run' menu and select 'Run Configurations.'

5. Select the Android project you wish to run/debug and open the 'Target' tab.

6. Ensure 'Always prompt to pick device' is selected, click 'Apply' and 'Run.'

7. The 'Android Device Chooser' will open. If you've connected your device successfully, it will be listed under 'Choose a running Android device.' Select your device and click 'OK.'

8. Check your device - your app will have made the leap from Eclipse onto your screen!

9. Create a phonegap application to query the device orientation in the x, y, and z direction(Static Accelerometer).
