#How to get an app to show on home screen install#

If the user selects Install, the app is installed (available as standalone desktop app), and the Install button no longer shows (the onbeforeinstallprompt event no longer fires if the app is already installed). So when the button is clicked, the install prompt appears.

Set deferredPrompt to null since it is no longer needed.

Respond to the user's interaction with the prompt using the userChoice property, again available on the beforeinstallprompt event object.

Use the prompt() method available on the beforeinstallprompt event object (stored in deferredPrompt) to trigger showing the install prompt.

Hide the button again with display: none - it is no longer needed once the app is installed.

The click handler contains the following steps:

Set the button to display: block so it appears in the UI for the user to click.

Store the event object in the deferredPrompt variable so it can be used later on to perform the actual installation.

Call Event.preventDefault() to stop Chrome 67 and earlier from calling the install prompt automatically (this behavior changed in Chrome 68).

addEventListener ( 'beforeinstallprompt', ( e ) => ) The manifest for our sample app looks like this: Also, be aware that Chrome requires this before it will display the install banner, whereas Firefox doesn't require it for showing the home-with-a-plus icon. Note that this has to be a relative URL pointing to the site index, relative to the url of the manifest.

start_url: Provides a path to the asset that should be loaded when the added-to-Home screen app is launched.

You are advised to provide both if your app's name is particularly long.

#How to get an app to show on home screen full#

name provides the full app name, and short_name provides a shortened name to be used when there is insufficient space to display the full name.

name/ short_name: These fields provide an app name to be displayed when representing the app in different places.

icons: Specifies icons for the browser to use when representing the app in different places (such as on the task switcher, or more important, the Home screen).

To make it feel like a distinct app (and not just a web page), you should choose a value such as fullscreen (no UI is shown at all) or standalone (very similar, but system-level UI elements such as the status bar might be visible).

display: Specifies how the app should be displayed.

The most relevant one to A2HS is the splash screen displayed when the app icon on the Home screen is tapped and it first starts to load (this currently appears only when apps have been added to the Home screen by Chrome).

background_color: Specifies a background color to be used in some app contexts.

The fields needed for A2HS are as follows:

webmanifest extension is specified in the Media type registration section of the specification, but generally browsers will support manifests with other appropriate extensions, e.g.json. If you have Mobile Chrome available, the experience is slightly different upon loading our site, you'll see an install banner pop up asking whether you want to add this app to your Home screen.

(Note: In Android 8 and higher, a system-level 'Add to Home screen' permission dialog will be shown first.) Tapping this will show a confirmation banner - pressing the big + ADD TO HOME SCREEN button completes the action, adding the app to the Home screen. You'll see fox pictures, but more important, you'll see a 'home' icon with a plus (+) icon inside it - this is the 'Add to Home screen' icon displayed for any site that has the necessary features in place.

If you have Firefox for Android available, use it to navigate to our demo at.

The example displays a series of fox pictures. We've written a very simple example web site ( see our demo live, and also see the source code) that doesn't do much, but was developed with the necessary code to allow it to be added to a Home screen, as well as a service worker to enable it to be used offline.
