Open the command-line tool and create a new PhoneGap project using the PhoneGap CLI you installed before. This will create a new directory called DeviceApi in your current working directory; this can be done using the following command:

$ phonegap create DeviceApi

Move to the directory you just created:

$ cd DeviceApi

Add the platforms you want to test on the device API. For this example, we add the Android platform:

$ cordova platform add android

Delete all the files and subdirectories except index.html inside the www directory. Open the index.html file you will find in the www root folder and add the following HTML code snippet:

<button type="button" onclick="addCountry()">Add Canada</button> <br/><br/>
<button type="button" onclick="get1Data()">Get USA Data</button> <br/><br/>
<button type="button" onclick="getAllData()">Get All Data</button> <br/><br/&gt...
