Config.xml

Config.xml is a global configuration file that controls many aspects of a cordova application's behavior. This platform-agnostic XML file is arranged based on the W3C's Packaged Web Apps (Widgets) specification, and extended to specify core Cordova API features, plugins, and platform-specific settings.

For projects created with the Cordova CLI (described in The Command-Line Interface), this file can be found in the top-level directory:

app/config.xml

Note that before version 3.3.1-0.2.0, the file existed at app/www/config.xml, and that having it here is still supported.

When using the CLI to build a project, versions of this file are passively copied into various platforms/ subdirectories. For example:

app/platforms/ios/AppName/config.xml
app/platforms/blackberry10/www/config.xml
app/platforms/android/res/xml/config.xml

In addition to the various configuration options detailed below, you can also configure an application's core set of images for each target platform. See Customize icons topic for more information.

Attributes(type)
Only for platform:
Description
AllowInlineMediaPlayback(boolean)
iOS
Default: false
Set to true to allow HTML5 media playback to appear inline within the screen layout, using browser-supplied controls rather than native controls. For this to work, add the webkit-playsinline attribute to any <video> elements.
AndroidLaunchMode(string)
Android
Default: singleTop
Allowed values: standard, singleTop, singleTask, singleInstance
Sets the Activity android:launchMode attribute. This changes what happens when the app is launched from app icon or intent and is already running.

Sets the maxSdkVersion attribute of the <uses-sdk> tag in the project's AndroidManifest.xml (see here).
android-minSdkVersion(integer)
Android
Default: Dependent on cordova-android Version
Sets the minSdkVersion attribute of the <uses-sdk> tag in the project's AndroidManifest.xml (see here).
android-targetSdkVersion(integer)
Android
Default: Dependent on cordova-android Version
Sets the targetSdkVersion attribute of the <uses-sdk> tag in the project's AndroidManifest.xml (see here).
AppendUserAgent(string)
Android iOS
If set, the value will append to the end of old UserAgent of webview. When using with OverrideUserAgent, this value will be ignored.
BackgroundColor(string)
Android BlackBerry Windows
Sets the app's background color. Supports a four-byte hex value, with the first byte representing the alpha channel, and standard RGB values for the following three bytes.
For Windows, the alpha channel is ignored.
Note: transparent value will set the application tile background to the accent color on Windows.
BackupWebStorage(string)
iOS
Default: cloud
Allowed values: none, local, cloud.
Set to cloud to allow web storage data to backup via iCloud. Set to local to allow only local backups via iTunes sync. Set to none prevent web storage backups.
ChildBrowser(string)
BlackBerry
Default: enable
Disables child browser windows. By default, apps launch a secondary browser window to display resources accessed via window.open() or by specifying a _blank anchor target. Specify disable to override this default behavior.
CordovaWebViewEngine(string)
iOS
Default: CDVUIWebViewEngine
This sets the WebView engine plugin to be used to render the host app. The plugin must conform to the CDVWebViewEngineProtocol protocol. The 'value' here should match the 'feature' name of the WebView engine plugin that is installed. This preference usually would be set by the WebView engine plugin that is installed, automatically.
DefaultVolumeStream(string)
Android
Default: default
Added in cordova-android 3.7.0, This preference sets which volume the hardware volume buttons link to. By default this is "call" for phones and "media" for tablets. Set this to "media" to have your app's volume buttons always change the media volume. Note that when using Cordova's media plugin, the volume buttons will dynamically change to controlling the media volume when any Media objects are active.
DisallowOverscroll(boolean)
iOS Android
Default: false
Set to true if you don't want the interface to display any feedback when users scroll past the beginning or end of content. On iOS, overscroll gestures cause content to bounce back to its original position. on Android, they produce a more subtle glowing effect along the top or bottom edge of the content.
EnableViewportScale(boolean)
iOS
Default: false
Set to true to allow a viewport meta tag to either disable or restrict the range of user scaling, which is enabled by default. Place a viewport such as the following in the HTML to disable scaling and fit content flexibly within the rendering WebView:
<meta name='viewport' content='width=device-width, initial-scale=1, user-scalable=no' />
EnableWebGL(boolean)
OS X
Default: false
(OS X 4.0.0+) Set to true to enable WebGL on the web view.
ErrorUrl(URL)
Android
Default: null
If set, will display the referenced page upon an error in the application instead of a dialog with the title "Application Error".
ErrorUrl(string)
iOS
If set, will display the referenced local page upon an error in the application.
FullScreen(boolean)
Android
Default: false
Allows you to hide the status bar at the top of the screen.
Note: Recommended platform-agnostic way to achieve this is to use the StatusBar plugin.
GapBetweenPages(float)
iOS
Default: 0
The size of the gap, in points, between pages.
HideKeyboardFormAccessoryBar(boolean)
BlackBerry
Default: false
Set to true to hide the additional toolbar that appears above the keyboard, helping users navigate from one form input to another.
HideMousePointer(integer)
OS X
Default: -1
(OS X 4.0.0+) Sets the timeout for hiding the mouse pointer. Set to 0 for immediate, set to -1 for never.
InAppBrowserStorageEnabled (boolean)
Android
Default: true
Controls whether pages opened within an InAppBrowser can access the same localStorage and WebSQL storage as pages opened with the default browser.
KeepRunning(boolean)
Android
Default: true
Determines whether the application stays running in the background even after a pause event fires. Setting this to false does not kill the app after a pause event, but simply halts execution of code within the cordova webview while the app is in the background.
KeyboardDisplayRequiresUserAction(boolean)
iOS
Default: true
Set to false to allow the keyboard to appear when calling focus() on form inputs.
LoadUrlTimeoutValue(number in milliseconds)
Android
Default: 20000, 20 seconds
When loading a page, the amount of time to wait before throwing a timeout error.
LoadingDialog(string)
Android
Default: null
If set, displays a dialog with the specified title and message, and a spinner, when loading the first page of an application. The title and message are separated by a comma in this value string, and that comma is removed before the dialog is displayed.
LogLevel(string)
Android
Default: ERROR
Allowed values: ERROR, WARN, INFO, DEBUG, VERBOSE
Sets the minimum log level through which log messages from your application will be filtered.
MediaPlaybackAllowsAirPlay(boolean)
iOS
Default: true
Set to false to prevent Air Play from being used in this view. Available in default UIWebView and WKWebView.
MediaPlaybackRequiresUserAction(boolean)
iOS
Default: false
Set to true to prevent HTML5 videos or audios from playing automatically with the autoplay attribute or via JavaScript.
Min/Max Version(Regex)
Windows
Allowed values: /(Microsoft.+? | Windows.+?)-(MinVersion | MaxVersionTested)/i
Identifies the ecosystems and their min/max versions the app is compatible with. There are three parts to each value: the SDK, the version restriction, and the version value. These preferences are detected by beginning with Windows or Microsoft and ending in -MinVersion or -MaxVersionTested:
  • The SDK defines what specialized platform you want to target. The default is Windows.Universal. Valid values for these are defined in the AppxManifest schema, in the Package/Depednencies/TargetPlatform elements.
  • The version restriction defines application compatibility rules. For example, if the -MinVersion is set to 10.1.0.0, then OS versions which don't support at least 10.1.0.0 of the corresponding SDK won't be able to load it. Similarly you can also use -MaxVersionTested which specifies the highest-tested version of the SDK. If a new version of the corresponding SDK is released, it will run in compatibility mode for the specified version.
  • The version value is a 4-integer tuple in the form of major.minor.build.qfe.
If no preferences of these types are specified in your config.xml file, then Windows.Universal version 10.0.0.0 will be chosen by default.
Note: These preferences are only set in the appxmanifest files of the desired target-platform and not in the jsproj files.
Orientation(string) Default: default
Allowed values: default, landscape, portrait
Allows you to lock orientation and prevent the interface from rotating in response to changes in orientation.
NOTE: The default value means Cordova will strip the orientation preference entry from the platform's manifest/configuration file allowing the platform to fallback to its default behavior. For iOS, to specify both portrait & landscape mode you would use the platform specific value 'all'.
OSXLocalStoragePath(string)
OS X
Default: ~/Library/Application Support/{bundle.id}
(OS X 4.0.0+) Sets the directory for the local storage path.
OverrideUserAgent(string)
Android
If set, the value will replace the old UserAgent of webview. It is helpful to identify the request from app/browser when requesting remote pages. Use with caution, this may causes compitiable issue with web servers. For most cases, use AppendUserAgent instead.
PageLength(float)
iOS
Default: 0
The size of each page, in points, in the direction that the pages flow. When PaginationMode is right to left or left to right, this property represents the width of each page. When PaginationMode is topToBottom or bottomToTop, this property represents the height of each page. The default value is 0, which means the layout uses the size of the viewport to determine the dimensions of the page.
PaginationBreakingMode(string)
iOS
Default: page
Allowed values: page, column
Valid values are page and column.The manner in which column- or page-breaking occurs. This property determines whether certain CSS properties regarding column- and page-breaking are honored or ignored. When this property is set to column, the content respects the CSS properties related to column-breaking in place of page-breaking.
PaginationMode(string)
iOS
Default: unpaginated
Allowed values: unpaginated, leftToRight, topToBottom, bottomToTop, rightToLeft
This property determines whether content in the web view is broken up into pages that fill the view one screen at a time,or shown as one long scrolling view. If set to a paginated form, this property toggles a paginated layout on the content, causing the web view to use the values of PageLength and GapBetweenPages to relayout its content.
PopupBlocker(string)
BlackBerry
Default: enable
Enables the popup blocker, which prevents calls to window.open(). By default, popups display in a child browser window. Setting the preference to enable prevents it from displaying at all.
SetFullscreen(boolean)
Android
Default: false
Same as the Fullscreen parameter in the global configuration of this xml file. This Android-specific element is deprecated in favor of the global Fullscreen element, and will be removed in a future version.
ShowTitle(boolean)
Android
Default: false
Show the title at the top of the screen.
SplashScreenBackgroundColor
Windows
Default: #464646
Sets the splashscreen background color. Supports a CSS color name or a four-byte hex value, with the first byte representing the alpha channel, and standard RGB values for the following three bytes.
The alpha channel is ignored although transparent value will cause black/white background color in case of Dark/Light theme accordingly.
Suppresses3DTouchGesture(boolean)
iOS
Default: false
Set to true to avoid 3D Touch capable iOS devices rendering a magnifying glass widget when the user applies force while longpressing the webview. Test your app thoroughly since this disables onclick handlers, but plays nice with ontouchend. If this setting is true, SuppressesLongPressGesture will effectively be true as well.
SuppressesIncrementalRendering(boolean)
iOS
Default: false
Set to true to wait until all content has been received before it renders to the screen.
SuppressesLongPressGesture(boolean)
iOS
Default: false
Set to true to avoid iOS9+ rendering a magnifying glass widget when the user longpresses the webview. Test your app thoroughly since this may interfere with text selection capabilities.
TopActivityIndicator(string)
iOS
Default: gray
Allowed values: whiteLarge, white, gray.

Controls the appearance of the small spinning icon in the status bar that indicates significant processor activity.
uap-target-min-version(string)
Windows
This property sets the MinTargetVersion for the Windows UAP. If not specified, this is set to the initial release version 10.0.10240.0
Note: This preference is set in the jsproj file and not in the appxmanifest file. So users with OS version lower than this value would not be able to run the app.
UIWebViewDecelerationSpeed(string)
iOS
Default: normal
Allowed values: normal, fast
This property controls the deceleration speed of momentum scrolling. normal is the default speed for most native apps, and fast is the default for Mobile Safari.
WebSecurity(string)
BlackBerry
Default: enable
Set to disable to override web security settings, allowing access to remote content from unknown sources. This preference is intended as a development convenience only, so remove it before packaging the app for distribution. For the released app, all URIs should be known and whitelisted using the element, described in the Domain Whitelist Guide.
WindowSize(string)
OS X
Default: auto
(OS X 4.0.0+) Sets the size of the application window.
Accepts the format WxH for a specific width and height or the special values auto and fullscreen. The latter will open a borderless window spanning the entire desktop area. Please note, that this is different from the normal OS X fullscreen mode, which would never span multiple displays.
Note: The global cordova fullscreen preference has no effect in OS X.
WindowsDefaultUriPrefix(string)
Windows
Allowed values: ms-appx://, ms-appx-web://
Identifies whether you want your app to target the local context or remote context as its startup URI. When building for Windows 10, the default is the remote context (ms-appx-web://).
In order to have a local-mode application that is not impacted by Remote Mode capability restrictions, you must set this preference to ms-appx:// and not declare any <access> elements with remote URIs. The local mode is the default for Windows 8.1
WindowsStoreDisplayName(string)
Windows
A friendly name for the publisher that can be displayed to users.
WindowsStoreIdentityName(string)
Windows
Identity name used for Windows store. The identity defines a globally unique identifier for a package. A package identity is represented as a tuple of attributes of the package. See the identity page on the package manifest schema reference for further details.
WindowsStorePublisherName(string)
Windows
Publisher Display Name.
WindowsToastCapable(boolean)
Windows
Default: false
A value of true indicates that the app is allowed to provide 'toast notifications'.
deployment-target(string)
iOS
This sets the IPHONEOSDEPLOYMENTTARGET in the build, which ultimately tranlsates to the MinimumOSVersion in the ipa. For more details please refer to Apple's documentation on Deployment Target Settings
target-device(string)
iOS
Default: universal
Allowed values: handset, tablet, universal
This property maps directly to TARGETEDDEVICEFAMILY in the xcode project. Note that if you target universal (which is the default) you will need to supply screen shots for both iPhone and iPad or your app may be rejected.
windows-phone-target-version(string)
Windows
Sets the version of Windows Phone for which the package (resulting from cordova build) will target. If none is specified, it will be set to the same version as windows-target-version (if found).
windows-target-version(string)
Windows
Sets the version of Windows for which the package (resulting from cordova build) will target. If none is specified, it will be set to '8.1'.

feature

If you use the CLI to build applications, you use the plugin command to enable device APIs. This does not modify the top-level config.xml file, so the element does not apply to your workflow. If you work directly in an SDK and using the platform-specific config.xml file as source, you use the tag to enable device-level APIs and external plugins. They often appear with custom values in platform-specific config.xml files. See the API Reference for details on how to specify each feature. See the Plugin Development Guide for more information on plugins. NOTE: Most of the time, you do NOT want to set this directly.

Attributes(type)
Only for platform:
Description
name(string) Required
The name of the plugin to enable.

param

Used to specify what certain plugin parameters such as: what package to retrieve the plugin code from, and whether the plugin code is to be initialized during the Webview's initialization.

Attributes(type)
Only for platform:
Description
name(string)
iOS OS X Android
Required
Allowed values: android-package, ios-package, osx-package, onload.
'ios-package', 'osx-package' and 'android-package' are used to specify the name of the package (as specified by the 'value' attribute) to be used to initialize the plugin code, while 'onload' is used to specify whether the corresponding plugin (as specified in the 'value' attribute) is to be instantiated when the controller is initialized.
value(string or boolean)
iOS OS X Android
Required
Specifies the name of the package to be used to initialize the plugin code (when the 'name' attribute is android-package, ios-package or osx-package), specifies the name of the plugin to be loaded during controller initialization (when 'name' attribute is set to 'onload').

Examples:

<!-- Here is how to specify the Device API for Android projects -->
<feature name="Device">
   <param name="android-package" value="org.apache.cordova.device.Device" />
</feature>

<!-- Here's how the element appears for iOS projects -->
<feature name="Device">
   <param name="ios-package" value="CDVDevice" />
   <param name="onload" value="true" />
</feature>

<!-- Here's how the element appears for OS X projects -->
<feature name="Device">
   <param name="osx-package" value="CDVDevice" />
   <param name="onload" value="true" />
