SplashScreens are displayed when your app starts. The way they work depends on the platform you are running on.

Web Apps

Web Apps show splash screens when saved to the Home Screen. The implementation is different in iOS and Android.

iOS

(Splash screens for Home Screen apps do not work for iOS 9.0 to 9.2. It's an iOS problem.)

Images must be supplied for all the supported screen sizes.

Here's how to add splash screens:

  1. Add folder named 'splash' to your project directory.
  2. Drag it into the Project Explorer
  3. Add a folder named 'ios' to the new 'splash' folder.
  4. In the ios folder, put the following files:
  320X460.png
  640x920.png
  640x1096.png
  748x1024.png
  768x1004.png
  1496x2046.png
  1536x2008.png
New for iPhone 6 and 6 Plus:
  1242x2148.png
  2208x1182.png
  750x1284.png

The resulting file structure will look something like this:

Android

Splash screen support for Home screen apps was added in Chrome 47. If you do not provide any additional splash screen information, it will default to the app's icon centered in the screen, on a white background. Chrome does not presently allow splash screens to be disabled if launched in fullscreen or standalone display modes.

Here's how to customize your splash screen:

  1. Make sure ChromeSplash in Project Properties is True.
  2. Add folder named 'splash' to your project directory.
  3. Drag it into the Project Explorer
  4. Add a folder named 'android' to the new 'splash' folder.
  5. In the android folder, put the following files:
 192x192.png
 256x256.png
 384x384.png
 512x512.png
  • Android will choose the appropriate image depending on the device.
  • The image will be centered on the screen.
  • The 'description' contents from Project Properties will appear underneath the image.
  • The background color of the splash screen will be taken from 'backgroundColor' in Project Properties. This ensures there is no flicker moving from the splash screen to your app.
  • In Project Properties, you can specify a different color for the device's status bar by setting 'ThemeColor'.
  • In Project Properties, you can specify the Chrome 'Orientation' as any, natural, landscape or portrait.
  1. any - permits the app to freely rotate. Overrides a device's screen orientation rotation lock, if set.
  2. natural - allows normal app orientation rotation if the device's rotation lock is not set.
  3. landscape - forces landscape orientation regardless of device settings.
  4. portrait - forces portrait orientation regardless of device settings.
  • In Project Properties, you can select the 'Display' mode as fullscreen, standalone, minimal-ui or browser.
  1. standalone - launches like a native app in appearance.
  2. browser - launches the app in a browser window, complete with address bar and browser controls.

Neither the fullscreen nor minimal-ui modes are supported within Chrome at this time. Selecting them will cause the browser to fallback to the next lower mode.

PhoneGap Apps

The default PhoneGap SplashScreen must be set in Project Properties. The file needs to be in the top level of the project folder. PNG images work best: the filename should also be added to the Manifest property.

The same file structure can be used as in Web App for the rest of the splashscreens. Here's how it could look:

The Web App images can be in the same folder.

Android

A similar file structure is needed as for web apps, but the screen sizes are different:

Create a folder in your Splash folder called android. Add the following files:

 960x720.png
 640x480.png
 470x320.png
 426x320.png
 720x960.png
 480x640.png
 320x470.png
 320x426.png

Add the following lines to the PhoneGap configxml property:

<preference name="SplashScreenDelay" value="2000" />
<preference name="AutoHideSplashScreen" value="true" />
<gap:splash src="{splashscreen}"/>

<platform name="android">
  <splash src="splash/android/426x320.png" density="land-ldpi" />
  <splash src="splash/android/470x320.png" density="land-mdpi" />
  <splash src="splash/android/640x480.png" density="land-hdpi" />
  <splash src="splash/android/960x720.png" density="land-xhdpi" />
  
  <splash src="splash/android/320x426.png" density="port-ldpi" />
  <splash src="splash/android/320x470.png" density="port-mdpi" />
  <splash src="splash/android/480x640.png" density="port-hdpi" />
  <splash src="splash/android/720x960.png" density="port-xhdpi" />
</platform>

iOS

A similar file structure is needed as for web apps, but the screen sizes and file names are different. See the file names and sizes as they appear in the configxml property. Create files of your own with the same names and sizes.

Assuming you want all sizes, add the following lines to the PhoneGap configxml property:

<preference name="SplashScreenDelay" value="2000" />
<gap:splash src="{splashscreen}"/>

<platform name = "ios">
  <splash src='splash/ios/Default.png' width='320' height='480' />
  <splash src='splash/ios/Default@2x.png' width='640' height='960' />
  <splash src='splash/ios/Default-568h@2x.png' width='640' height='1136' />
  <splash src='splash/ios/Default-Portrait.png' width='768' height='1024' />
  <splash src='splash/ios/Default-Landscape.png' width='1024' height='768' />
  <splash src='splash/ios/Default-Portrait@2x.png' width='1536' height='2048' />
  <splash src='splash/ios/Default-Landscape@2x.png' width='2048' height='1536' />
</platform>
