Android check app installed

Is your app installed? getInstalledRelatedApps() will tell you!

The getInstalledRelatedApps() method allows your website to check whether
your iOS/Android/desktop app or PWA is installed on a user’s device.

What is the getInstalledRelatedApps() API? #

The getInstalledRelatedApps() makes it possible for your page to check if your mobile or desktop app, or in some cases, if your Progressive Web App (PWA) is already installed on a user’s device, and allows you to customize the user experience if it is.

For example, if your app is already installed:

• Redirecting the user from a product marketing page directly into your app.
• Centralizing some functionality like notifications in the other app to prevent duplicate notifications.
• Not promoting the installation of your PWA if your other app is already installed.

To use the getInstalledRelatedApps() API, you need to tell your app about your site, then tell your site about your app. Once you’ve defined the relationship between the two, you can check if the app is installed.

Supported app types you can check #

App type	Checkable from
Android app	Android only Chrome 80 or later
Windows (UWP) app	Windows only Chrome 85 or later Edge 85 or later
Progressive Web App Installed in the same scope or a different scope.	Android only Chrome 84 or later

The getInstalledRelatedApps() API only allows you to check if your apps are installed. You cannot get a list of all installed apps, or check if other 3rd party apps are installed.

Check if your Android app is installed #

Your website can check if your Android app is installed.

Android: Chrome 80 or later

Tell your Android app about your website #

First, you’ll need to update your Android app to define the relationship between your website and Android application using the Digital Asset Links system. This ensures that only your website can check if your Android app is installed.

In the AndroidManifest.xml of your Android app, add an asset_statements entry:

Then, in strings.xml , add the following asset statement, updating site with your domain. Be sure to include the escaping characters.

Once completed, publish your updated Android app to the Play store.

Tell your website about your Android app #

Next, tell your website about your Android app by adding a web app manifest to your page. The manifest must include the related_applications property, an array that provides the details about your app, including platform and id .

• platform must be play
• id is the GooglePlay application ID for your Android app

Check if your app is installed #

Finally, call navigator.getInstalledRelatedApps() to check if your Android app is installed.

Check if your Windows (UWP) app is installed #

Your website can check if your Windows app (built using UWP) is installed.

Windows: Chrome 85 or later, Edge 85 or later

Tell your Windows app about your website #

You’ll need to update your Windows app to define the relationship between your website and Windows application using URI Handlers. This ensures that only your website can check if your Windows app is installed.

Add the Windows.appUriHandler extension registration to your app’s manifest file Package.appxmanifest . For example, if your website’s address is example.com you would add the following entry in your app’s manifest:

Note, you may need to add the uap3 namespace to your

Then, create a JSON file (without the .json file extension) named windows-app-web-link and provide your app’s package family name. Place that file either on your server root, or in the /.well-known/ directory. You can find the package family name in the Packaging section in the app manifest designer.

See Enable apps for websites using app URI handlers for complete details on setting up URI handlers.

Tell your website about your Windows app #

Next, tell your website about your Windows app by adding a web app manifest to your page. The manifest must include related_applications property, an array that provides the details about your app, including platform and id .

• platform must be windows
• id is your app’s package family name, appended by the Id value in your Package.appxmanifest file.

Check if your app is installed #

Finally, call navigator.getInstalledRelatedApps() to check if your Windows app is installed.

Check if your Progressive Web App is already installed (in scope) #

Your PWA can check to see if it is already installed. In this case, the page making the request must be on the same domain, and within the scope of your PWA, as defined by the scope in the web app manifest.

Android: Chrome 84 or later

Tell your PWA about itself #

Tell your PWA about itself by adding a related_applications entry in your PWAs web app manifest.

• platform must be webapp
• url is the full path to the web app manifest of your PWA

Check if your PWA is installed #

Finally, call navigator.getInstalledRelatedApps() from within the scope of your PWA to check if it is installed. If getInstalledRelatedApps() is called outside the scope of your PWA, it will return false. See the next section for details.

Check if your Progressive Web App is installed (out of scope) #

Your website can check if your PWA is installed, even if the page is outside the scope of your PWA. For example, a landing page served from /landing/ can check if the PWA served from /pwa/ is installed, or if your landing page is served from www.example.com and your PWA is served from app.example.com .

Android: Chrome 84 or later

Tell your PWA about your website #

First, you’ll need to add digital asset links to the server where your PWA is served from. This will help define the relationship between your website and your PWA, and ensures that only your website can check if your PWA is installed.

Add an assetlinks.json file to the /.well-known/ directory of the domain where the PWA lives, for example app.example.com . In the site property, provide the full path to the web app manifest that will perform the check (not the web app manifest of your PWA).

Double check the file name when you create your assetlinks.json file, I’ve wasted many hours debugging, only to realize I’d added an extra ‘s’ in the file name.

Tell your website about your PWA #

Next, tell your website about your PWA app by adding a web app manifest to your page. The manifest must include the related_applications property, an array that provides the details about your PWA, including platform and url .

• platform must be webapp
• url is the full path to the web app manifest of your PWA

Check if your PWA is installed #

Finally, call navigator.getInstalledRelatedApps() to check if your PWA is installed.

Calling getInstalledRelatedApps() #

Calling navigator.getInstalledRelatedApps() returns a promise that resolves with an array of your apps that are installed on the user’s device.

To prevent sites from testing an overly broad set of their own apps, only the first three apps declared in the web app manifest will be taken into account.

Like most other powerful web APIs, the getInstalledRelatedApps() API is only available when served over HTTPS.

Still have questions? #

Still have questions? Check the getInstalledRelatedApps tag on StackOverflow to see if anyone else has had similar questions. If not, ask your question there, and be sure to tag it with the progressive-web-apps tag. Our team frequently monitors that tag and tries to answer your questions.

Did you find a bug with Chrome’s implementation? Or is the implementation different from the spec?

• File a bug at https://new.crbug.com. Include as much detail as you can, provide simple instructions for reproducing the bug, and enter Mobile>WebAPKs in the Components box. Glitch works great for sharing quick and easy repros.

Show support for the API #

Are you planning to use the getInstalledRelatedApps() API? Your public support helps the Chrome team to prioritize features and shows other browser vendors how critical it is to support them.

• Share how you plan to use the API on the WICG Discourse thread.
• Send a tweet to @ChromiumDev using the hashtag #getInstalledRelatedApps and let us know where and how you’re using it.
