Project Settings
================

You can set various application configuration parameters using a platform-agnostic configuration file, `config.xml`.
This file is based on the W3C [Packaged Web Apps (Widgets)](http://www.w3.org/TR/widgets/) specification.

The location of the `config.xml` file is different depending on the platform. The contents, in general, are not.

## Platform-Specific Properties

As with any abstraction layer, Apache Cordova cannot be a perfect silver bullet. As such, some native and platform-specific
properties, characteristics and behaviours are encapsulated as much as possible as `<preference>` elements inside the
`config.xml` file. The following sub-sections linked to are guides which go into more details about these preferences.

## config.xml Elements

The [Apache Cordova](http://cordova.io) project strives abstract away native platform specifics via web-inspired and web-based
abstractions that are heavily standards driven and adopted by the web community. Please take a few minutes to familiarize
yourself with the [config.xml specification](http://www.w3.org/TR/widgets/), to understand the type of application metadata the
Apache Cordova project aims to abstract and provide simple entry points for.

An example:

        <widget>
            <preference name="MySetting" value="true" />
            <plugins>
                <plugin name="MyPlugin" value="MyPluginClass" />
            </plugins>
            <access origin="*" />
        </widget>

A list of supported elements across major platforms which are supported in Apache Cordova follow.

### `<plugin>`

These elements map to native APIs that the application accesses. At
runtime, the Apache Cordova framework checks the `<plugin>` elements
and maps them to native code to enable your Cordova application to
access device APIs otherwise unavailable to typical web-based
applications.

### `<access>`

These elements define how your whitelist works. Please see the
[Domain Whitelist Guide](../whitelist/index.html) for more information.

### `<content>`

This element defines your application's start page relative to the
project's standard web assets root folder. The default is
`index.html`.
