## Example Configuration
|
||||
In the top-level `config.xml` file (not the one in `platforms`), add configuration elements like those specified here.
|
||||
|
||||
Please notice that the value of the "src" attribute is relative to the project directory and not to the www directory. You can name the source image whatever you like. The internal name in the app is determined by Cordova.

#### config.xml

|

- __SplashScreen__ (string). The resource name which is used for the displaying splash screen. Different platforms use values for this.
|
||||
|
||||
<preference name="SplashScreen" value="resourcename" />
|
||||
|
||||
- __AutoHideSplashScreen__ (boolean, default to `true`). Indicates wherether hide splash screen automatically or not. Splash screen hidden after amount of time specified in the `SplashScreenDelay` preference.
|
||||
|
||||
<preference name="AutoHideSplashScreen" value="true" />
|
||||
```xml
|
||||
<preference name="AutoHideSplashScreen" value="true" />
|
||||
```
|
||||
|
||||
- __SplashScreenDelay__ (number, default to 3000). Amount of time in milliseconds to wait before automatically hide splash screen.
|
||||
|
||||
<preference name="SplashScreenDelay" value="3000" />
|

### Android Quirks
|
||||
|
||||
In your `config.xml`, you need to add the following preferences:
|
||||
|
||||
<preference name="SplashScreen" value="foo" />
|
||||
<preference name="SplashScreenDelay" value="3000" />
|
||||
<preference name="SplashMaintainAspectRatio" value="true|false" />
|
||||
<preference name="SplashShowOnlyFirstTime" value="true|false" />
|
||||
```xml
|
||||
<preference name="SplashScreenDelay" value="3000" />
|
||||
<preference name="SplashMaintainAspectRatio" value="true|false" />
|
||||
<preference name="SplashShowOnlyFirstTime" value="true|false" />
|
||||
```
|
||||
|
||||
Where foo is the name of the splashscreen file, preferably a 9 patch file. Make sure to add your splashcreen files to your res/xml directory under the appropriate folders. The second parameter represents how long the splashscreen will appear in milliseconds. It defaults to 3000 ms. See [Icons and Splash Screens](http://cordova.apache.org/docs/en/edge/config_ref_images.md.html)
|
||||
for more information.
|
||||
The first parameter represents how long the splashscreen will appear in milliseconds. It defaults to 3000 ms.
|
||||
|
||||
"SplashMaintainAspectRatio" preference is optional. If set to true, splash screen drawable is not stretched to fit 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.

### Android and iOS Quirks
|

|

- In iOS, the splashscreen images are called launch images. These images are mandatory on iOS.

- `FadeSplashScreen` (boolean, defaults to `true`): Set to `false` to

state changes.

||||
<preference name="FadeSplashScreen" value="false"/>
|

```xml
|
||||
<preference name="FadeSplashScreen" value="false"/>
|
||||
```
|
||||
|
||||
- `FadeSplashScreenDuration` (float, defaults to `3000`): Specifies the
|
||||
number of milliseconds for the splash screen fade effect to execute.

|
||||
<preference name="FadeSplashScreenDuration" value="3000"/>
|
||||
```xml
|
||||
<preference name="FadeSplashScreenDuration" value="3000"/>

||||
```
|
||||
|
||||
Note also that this value used to be seconds, and not milliseconds, so values less than 30 will still be treated as seconds. ( Consider this a deprecated patch that will disapear in some future version. )
