# Where can I find cordova.js?

Cordova.js is a very important JavaScript file within Cordova/PhoneGap.
It allows you to access the hardware of your Android device via plugins.

IMPORTANT

Most plugins will ALMOST NEVER work if the link to cordova.js is missing!

<body>
    <div class="app">
        <h1>Apache Cordova</h1>
        <div id="deviceready" class="blink">
            <p class="event listening">Connecting to Device</p>
            <p class="event received">Device is Ready</p>
        </div>
    </div>
    <script src="cordova.js"></script>
    <script src="js/index.js"></script>
</body>

Examine the structure of the starting project (and of all the examples that follow).
In the code, the file cordova.js is on the same level as index.html.
As you can see, this file does not exist at all and you should not add it yourself!
Every time you compile the app for the browser or for Android, the compiler will add the cordova.js file to the project itself.
Cordova.js will contain the same functions for each platform, but the content of the functions are different!

# phonegap serve

Open the platforms/browser/www folder.
Here you will find a copy of the original project, plus some additional files including cordova.js.

# cordova run android

In the console you find the path to the compiled apk file.
Duplicate app-debug.apk to the desktop.
Change the extension .apk to .zip.
Unzip the app-debug.zip file and examine its contents.
Here you will find a copy of the original project, plus some additional files including cordova.js.

TIP

Now open both cordova.js files and you will notice that the content is different.
