This plugin displays and hides a splash screen while your web application is launching. Using its methods you can also show and hide the splash screen manually.
- Windows (`cordova-windows` version >= 4.4.0 is required)
__Note__: Extended splashscreen does not require the plugin on Windows (as opposed to Android and iOS) in case you don't use the plugin API, i.e. programmatic hide/show.
In the top-level `config.xml` file (not the one in `platforms`), add configuration elements like those specified here.
The value of the "src" attribute is relative to the project root directory and NOT to the `www` directory (see `Directory structure` below). You can name the source image file whatever you like. The internal name in the application is automatically determined by Cordova.
Directory structure:

<!-- you can use any density that exists in the Android project -->
There are two mechanisms for displaying a launch screen on iOS:
1. Legacy launch images: images are sized exactly for the device's screen size. Does not support the iPad Pro 12.9's native resolution or split-screen/slide-over multitasking.
2. Launch storyboard images: Images are sized based on scale, idiom, and size classes. Supports all devices, and can be used with split-screen/slide-over multitasking.
Apple is moving away from legacy launch images. There is no official support for providing a native-resolution launch image for the iPad Pro 12.9 or for providing launch images that work with split-screen multitasking or slide-over. If your app doesn't need to support these contexts, then you can continue to use legacy launch images for as long as you like.
The preferred method of providing launch images is to use a launch storyboard. For native app developers, the ideal launch storyboard is an unpopulated version of the app's user interface at launch. For non-native app developers who don't wish to learn Interface Builder, however, this plugin simulates the legacy launch image method as much as is feasible.
Technically the filename for the `src` attribute can be anything you want; the filenames are used because they match what will be used when your project is compiled. The width and height attributes determine which launch images are displayed on which devices as follows:
Note: It is vitally important that the source image actually matches the size specified in the `width` and `height` attributes. If it does not, the device may fail to render it properly, if at all.
#### Launch storyboard images
In order to support newer form factors and split-screen/slide-over multitasking, you should use launch storyboard images. These are similar to the legacy launch images above, but there are crucial differences:
- images are not specific to a given device.
- images are scaled to fill the available viewport (while maintaining the aspect ratio).
- the outer edges of the images will be cropped, and the amount will vary based on device an viewport.
- there is no need to provide an image for each possible device, viewport, and orientation; iOS will choose the best image for the situation automatically.
##### Designing launch storyboard images
The key to designing a launch storyboard image is understanding that the edges of the image will almost certainly be cropped. Therefore, one should not place any important information near the edges of any images provided to the launch storyboard. Only the center is a safe area, and this all but guarantees that following Apple's advice of presenting an unpopulated user interface will not work well.
Instead, the following tips should enable you to create a launch image that works across a multitude of form factors, viewports, and orientations:
- Important graphics (logos, icons, titles) should be centered. The safe bounding region will vary, so you will need to test to ensure that the important graphics are never cropped. Better yet, don't supply any important graphics in the first place.
- You _can_ fine-tune the placement and size of these graphics, but you don't have the same fine-grained control as you did with legacy launch images.
- Use a simple color wash. If you use two colors, you'll want one color to fill the top half of the image, and the second to fill the bottom half. If you use a gradient, you'll probably want to ensure that the middle of the gradient lines up with the center of the image.
- Don't worry about pixel perfection -- because the images are scaled, there's almost no chance the images will be perfectly fit to the pixel grid. Since all supported iOS devices use retina screens, users will be hard pressed to notice it anyway.
It is important to understand the concept of scale, idiom, and size class traits in order to use launch storyboard images effectively. Of the images supplied to the launch storyboard, iOS will choose the image that best matches the device and viewport and render that image. It is possible to supply only one launch image if so desired, but it is also possible to fine-tune the displayed launch image based on traits. When fine-tuning, one can ignore traits that aren't targeted or supported by the app.
> Note: If you are using launch storyboard images, there is no need to include legacy images. If you do, the legacy images will be copied, but not used.
##### Scale
| scale | devices |
|:-----------:|:----------------------:|
| 1x | All non-retina devices |
| 2x | Most retina devices |
| 3x | iPhone 6+/6s+,7s+ |
In general, you'll want to supply 2x and 3x images. Cordova only supports retina devices now, so there's no point in supplying 1x images.
##### Idioms
| idiom | devices |
|:-----------:|:-------------:|
| ipad | All iPads |
| iphone | All iPhones and iPod Touches |
| universal | All devices |
You only need to provide universal images unless you need to fine-tune for a specific device idiom.
##### Size classes
There are two size classes applies to both screen axes. Narrow viewports are considered to be the "compact" size class, and remaining viewports are considered "regular". When supplying images to Xcode, however, one must choose between "any & compact" and "any & regular". To stay consistent with the native terminology, this feature will match based on "any" and "compact". `any` will match regular-sized viewports.
Note: this feature uses `com` as an abbreviation for "compact" classes.
The following classes are supported by this feature:
To see the complete list of size classes associated with devices and viewports, see <http://www.sizeclasses.com>.
##### Single-image launch screen
If your launch image is simple, you may be able to avoid creating a lot of different launch images and supply only one. The launch image needs to meet the following requirements:
- the image should be square
- the image should be large enough to fit on an iPad Pro 12.9": 2732x2732
- anything important should fit within the center
Keep in mind that the image will be cropped, possibly quite severely, depending upon the viewport.
Once the image is created, you can include it in your project by adding the following to `config.xml`:
Because only one image is provided, iOS will utilize it in every context.
##### Multi-image launch screen
If a single launch image won't meet your needs, you will probably need to supply at least six images, if not more. Furthermore, keep in mind that it will not be possible to fine tune the image to a specific device, but only to a device class, display factor, and viewport size.
If you don't need to target images to a specific idiom, you should create six images, as follows:
Once you run the app on a target, iOS caches the launch image. Unfortunately, when you change the image, iOS does _not_ invalidate the cache, which means you'll still see the old launch image. You should either: delete the app, or reset content & settings (simulator).
2.**Simulator may not show expected images when launched from CLI**
When Xcode deploys to a specific simulator, it only copies the assets that match the simulator's characteristics. For example, if you try to run an app on the iPhone 6s Plus simulator, only @3x launch images are copied. When compiling from the CLI, however, the default is to assume an iPhone 5s, which means only @2x launch images are copied. Unless your launch images are markedly different, chances are good the difference would go unnoticed, but this does mean that the only accurate method of testing is to test on a physical device.
3.**`anyany` must be provided for other variations to be used**
If you don't provide an `anyany` version of the launch image for a specific scale and idiom, the other variations (like `anycom`, `comany`, and `comcom`) will ignored.
__Note__: SplashScreens size for Windows 10 project should not exceed 200 KBytes.
__Note__: Supported formats are `.png`, `.jpg`, `.jpeg`. Mixing of the extensions within a target is not supported. I.e. you can have `splashscreen.jpg` and `splashscreenphone.png` but not `splashscreen.scale-100.png`, `splashscreen.scale-400.jpg`.
__Note__: You may need to reopen Visual Studio solution after changing the images and doing a `cordova prepare` for the changes to take effect.
-`AutoHideSplashScreen` (boolean, default to `true`). Indicates whether to hide splash screen automatically or not. The splash screen is hidden after the amount of time specified in the `SplashScreenDelay` preference.
This value used to be in seconds (but is now milliseconds) so values less than 30 will continue to be treated as seconds. (Consider this a deprecated patch that will disapear in some future version.)
**Windows Quirk**: You should disable the splashscreen in case you are updating the entire document body dynamically (f.e. with a SPA router) to avoid affecting UI/controls.
Note that you should also directly reference `WinJS/base.js` in the page HTML in this case to avoid the issues with activation context ([CB-11658](https://issues.apache.org/jira/browse/CB-11658)).
**iOS Quirk**: to disable the splashscreen on `ios` platform you should also add `<preference name="FadeSplashScreenDuration" value="0"/>` to `config.xml`.
_Note_: `FadeSplashScreenDuration` is included into `SplashScreenDelay`, for example if you have `<preference name="SplashScreenDelay" value="3000" />` and `<preference name="FadeSplashScreenDuration" value="1000"/>` defined in `config.xml`:
Turning the fading off via `<preference name="FadeSplashScreen" value="false"/>` technically means fading duration to be `0` so that in this example the overall splash screen delay will still be 3 seconds.
_Note_: This only applies to the application startup - you need to take the fading timeout into account when manually showing/hiding the splash screen in your application's code:
`SplashMaintainAspectRatio` preference is optional. If set to `true`, the splash screen drawable is not stretched to fit the full screen, but instead simply "covers" the screen, like CSS "background-size:cover". This is very useful when splash screen images cannot be distorted in any way, for example when they contain scenery or text. This setting works best with images that have large margins (safe areas) that can be safely cropped on screens with different aspect ratios.
The splash screen plugin reloads the splash screen whenever the orientation changes so that you can specify different splash screen images for portrait and landscape orientations.
`SplashShowOnlyFirstTime` preference is optional and defaults to `true`. When set to `true` the splash screen will only appear on application launch. However, if you plan to use `navigator.app.exitApp()` to close the application and force the splash screen appear on the application's next launch, you should set this property to `false` (this also applies to closing the application with the Back button).
`SplashScreenSpinnerColor` preference is also optional and is ignored when not set. Setting it to a valid color name or HEX color code will change the color of the spinner on Android 5.0+ devices.
__Note__: `SplashScreen` value should be absolute in order to work in a sub-page. The `SplashScreen` value is used only for the browser platform. The value will be ignored for other platforms.
