Ionic Splash Screen Animation

Episode 88 written by Jeff Delaney

Every successful mobile app has one thing in common - a beautiful splash page and home screen icon. In this lesson, I will show you how to quickly customize your splash page and app icon in Ionic, then animate the splash intro.

Native mobile developers need to think about the appearance of these images across many devices - phones, tablets, and watches - all of which have different screen sizes and resolutions. Luckily, we can generate dozens of graphics in one fell swoop with the Ionic CLI.

There are several other tutorials that cover this topic, but they all leave you with ugly white screen upon initial entry. I’ll show you how to solve this issue to create a more polished transition.

Full source code for Ionic splash animation.

Generate an Ionic Splash Screen and App Icon with the CLI

You only need two source images to get started - an app icon that users will click from their device and the initial splash graphic.

The source images for our Ionic mobile resources

Save the Images

Override the default graphics below with your custom images.

  • /resources/icon.png - at least 1024x1024px
  • /resources/splash.png - at least 2732×2732px

Using the CLI

Make sure you have a native mobile platform added to the project.

ionic cordova platform add android

Now generate image resources for your app by running the following command from the terminal.

This should have magically created or updated the resource images in your project.

Animated Splash Screen

It you really want to impress your users, consider using an animated splash screen.

You can implement a nice looking animation with minimal effort by using an pre-built open source loader.

Avoiding the White or Gray Screen

If you’ve followed other tutorials about animated splash screens with Ionic, you’ve probably run into a 1 or 2 second white/gray screen before your animation loads. In my opinion, that completely crushes the polish we want from the animation.

BAD - Notice the brief 1 to 2 second white screen that flashes before the animation below.

GOOD - The best workaround in my opinion is to transition gracefully from your static image to the animation.

Update the Default Splash Screen Config

Our strategy is to show a static image splash first, then seamlessly blend in the animation. The CSS background will closely match the image background color, but we will hide the image as soon as possible when the platform becomes ready.

Update the config.xml file with the following lines.

<!-- omitted -->
<preference name="FadeSplashScreenDuration" value="300" />
<preference name="SplashScreenDelay" value="10000" />
<preference name="AutoHideSplashScreen" value="false" />
<preference name="FadeSplashScreen" value="true" />
<preference name="ShowSplashScreen" value="true" />

Hide and Show the Animation

In the app.html, we just need a div that will act as an overlay for several seconds after the platform is ready.

<div *ngIf="showSplash" class="splash">
<div class="spinner"></div>
</div>


<ion-nav [root]="rootPage" #content swipeBackEnabled="false"></ion-nav>

In the app.component.ts, we import an RxJS timer that will toggle the visibility of the overlay after 3000ms.

import { timer } from 'rxjs/observable/timer';

@Component({
templateUrl: 'app.html'
})
export class MyApp {

// ...omitted

showSplash = true; // <-- show animation

initializeApp() {
this.platform.ready().then(() => {

this.statusBar.styleDefault();
this.splashScreen.hide(); // <-- hide static image

timer(3000).subscribe(() => this.showSplash = false) // <-- hide animation after 3s
});
}
}

Animation Styles

The animation style is just an overlay that will expand to 100% width and height of the viewport. I am also using flexbox to center the content directly in the middle of the screen in a way that is responsive across devices. Add the styles in app.scss.

.splash {
position: absolute;
width: 100%;
height: 100%;
z-index: 999;
display: flex;
align-items: center;
justify-content: center;
background: #ff7400;
}

.spinner {
// your animation code (SpinKit used in this demo)
}

You can grab the spinner CSS from the open-source SpinKit project.

The End

It feels good to start off a new project with a suite of good looking graphics. I hope this gives you an idea of how to quickly customize the app icon and splash page in your next Ionic mobile app.
