Overview

Deep linking allows you to open a specific page within your app from an external source such as a website, email, or SMS. If the app is not installed, users are redirected to the appropriate app store. If on an unsupported platform, users are redirected to a fallback website. This guide covers setup and usage of deep linking across:
  • Android (App Links)
  • iOS (Universal Links and URL Schemes)
  • Push notifications
  • Emails
  • In-app messages
To function correctly, deep links must:

​
Android setup

Use Android Studio’s App Links Assistant to simplify setup.

​
Steps:

  1. Open Android Studio → Tools → App Links Assistant
  2. Follow steps to set up links to your site
  3. Android Studio auto-generates the required code and assetlinks.json file

​
Manifest example:

<activity android:name=".SecondActivity" android:exported="true">
  <intent-filter android:autoVerify="true">
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="https" />
    <data android:host="yoursite.com" />
  </intent-filter>
</activity>

​
Activity handler example:

Intent appLinkIntent = getIntent();
String appLinkAction = appLinkIntent.getAction();
Uri appLinkData = appLinkIntent.getData();
The generated assetlinks.json file must be hosted at:
