App Icons and Splash Images

info

You need to publish your application to see affects of changes. Smartface emulator won't be affected with customizations of app icon and splash image.

App Icons​

App icon is the icon of the application you have. App icons have fixed sizes for device types.

For Android devices, every resource folder is used for a different type of device. In each folder, there is an icon.png that represents your app icon. Please note that the image sizes are fixed.;

iOS resources have same structure. The difference is that iOS has only one resource folder and you need to change the images names to start with "Icon" . Please note that the images sizes are fixed.;

Changing the Application Icon & Splash Icon

To change your application icon or splash image, follow this documentation

Launch Image​

Launch image is the image which will be shown when the application first opens.

  • Name of launch image must be either
    • LaunchImage.png
    • LaunchImage.ios.png
    • LaunchImage.android.png
  • If LaunchImage.png is being used, then launch images for both platforms are generated
  • When the LaunchImage.ios.png or LaunchImage.android.png is being used then launch images for that specific platform are generated
caution
  • LaunchImage.ios.png
  • LaunchImage.android.png

Is valid for CLI but not for IDE.

Building Smartface Apps
Use square sized launch image

Developers must edit original launch image to make it square sized so that our image processor module can perform resizing & cropping accordingly

info

The name of Launch Image is splash_image on Android.

So you if you want to change your splash image only on Android, you need to find the image with name splash_image from images/Android and replace it with your new image.

tip

For Android, you can generate splash image with any name you want. But for iOS, you can only use LaunchImage as the name.

For example you have splash image named splash_image_dark.png you can generate it in images/automated by clicking on the image and select Generate auto-resized images. Then you can use splash_image_dark as the splash image on Android

Generating Launch Image on Android​

With Android 12 splash image creation changed, you can follow the below steps to create a splash image.

Splash Screen dimensions

The splash screen icon uses the same specifications as Adaptive icons, as follows:

  • Branded image: This should be 200×80 dp.

  • App icon with an icon background: This should be 240×240 dp, and fit within a circle of 160 dp in diameter.

  • App icon without an icon background: This should be 288×288 dp, and fit within a circle of 192 dp in diameter.

Processes​

  1. Go to images/automated folder.
  2. Place your splash image in the images/automated folder.
  3. Right click on the file and select "Generate auto-resized images".
