Mastering Universal/Deep Link Configuration: A Step-by-Step Guide

Are you tired of struggling with universal/deep link configuration when the final screen is on another stack? Do you find yourself lost in a sea of confusing instructions and technical jargon? Fear not, dear developer, for we’ve got you covered! In this comprehensive guide, we’ll take you by the hand and walk you through the process of configuring universal/deep links like a pro. So, buckle up and let’s dive in!

What are Universal/Deep Links?

Before we dive into the nitty-gritty of configuration, let’s quickly cover the basics. Universal/deep links are a type of link that allows users to navigate directly to a specific screen within your app, even if they don’t have the app installed. This is achieved through a combination of HTTP URLs and platform-specific linking mechanisms.

Think of it like a shortcut to a specific page within your app. Instead of directing users to the app store or a generic landing page, universal/deep links take them straight to the desired screen, providing a seamless user experience.

Why is Universal/Deep Link Configuration Important?

So, why is universal/deep link configuration so crucial? Here are just a few reasons:

• Improved User Experience: By taking users directly to the desired screen, you’re providing a seamless and personalized experience that boosts engagement and conversions.
• Increase App Installs: With universal/deep links, you can drive more installs by directing users to the app store or a specific screen within your app.
• Enhanced Analytics: Universal/deep links provide valuable insights into user behavior, allowing you to refine your marketing strategy and optimize your app’s performance.

Configuring Universal/Deep Links: A Step-by-Step Guide

Now that we’ve covered the basics, let’s get started with the configuration process! We’ll break it down into three main sections: iOS, Android, and Universal Links.

iOS Universal/Deep Link Configuration

iOS universal/deep links rely on Apple’s Universal Links framework. Here’s how to configure it:

1. Enable Associated Domains: In your Xcode project, go to Capabilities and toggle on Associated Domains.
2. Define Your Domain: Enter your domain in the Domains section, prefixed with applinks:. For example, applinks:example.com.
3. Create an AASA File: Create a JSON file named apple-app-site-association and upload it to your domain. This file contains the mapping between your app and your domain.
4. Handle Universal Links in Your App: In your app delegate, implement the application(_:continue:restorationHandler:) method to handle incoming universal links.

<?xml version="1.0" encoding="UTF-8"?>
<apple-app-site-association>
    <applinks>
        <apps>
            <app>TeamID.com.example.app</app>
        </apps>
        <details>
            <appID>TeamID.com.example.app</appID>
            <paths></paths>
        </details>
    </applinks>
</apple-app-site-association>

Android Universal/Deep Link Configuration

Android universal/deep links rely on Android App Links. Here’s how to configure it:

1. Declare Your Intent: In your AndroidManifest.xml file, declare an intent filter for your activity:

<intent-filter>
    <action android:name="android.intent.action.VIEW" />
    <category android:name="android.intent.category.DEFAULT" />
    <category android:name="android.intent.category.BROWSABLE" />
    <data android:scheme="http" android:host="example.com" />
</intent-filter>

2. Generate a Digital Asset Links File: Create a JSON file named assetlinks.json and upload it to your domain. This file contains the mapping between your app and your domain.
3. Verify Your Domain: Verify your domain ownership by adding a TXT record to your DNS settings.
4. Handle Universal Links in Your App: In your activity, override the onCreate() method to handle incoming universal links.

[{
  "relation": ["delegate_permission/common.handle_all_urls"],
  "target": {
    "namespace": "android_app",
    "package_name": "com.example.app",
    "sha256_cert_fingerprints": ["hash"]
  }
}]

Universal Links Configuration

Universal links provide a unified way to handle links across both iOS and Android. Here’s how to configure it:

1. Define Your Domain: Define your domain in your app’s configuration file (e.g., Info.plist on iOS or strings.xml on Android).
2. Create a Universal Links Server: Set up a server to handle universal link requests. This can be a custom server or a third-party service like Firebase Dynamic Links.
3. Generate a Universal Link: Generate a universal link using your server. This link will redirect users to the desired screen within your app.

Platform	Link Format
iOS	https://example.com/path?al_applink=applinks%3A%2F%2Fexample.com%2Fpath
Android	https://example.com/path?al_android_package=com.example.app

Troubleshooting Common Issues

Encountered an issue during the configuration process? Don’t worry, we’ve got you covered! Here are some common issues and their solutions:

• Universal links not working on iOS: Check that your AASA file is correctly formatted and uploaded to your domain. Ensure that your app is configured to handle universal links.
• Universal links not working on Android: Verify that your assetlinks.json file is correctly formatted and uploaded to your domain. Ensure that your app is configured to handle universal links.
• Universal links not redirecting to the correct screen: Check that your universal link is correctly formatted and that your app is handling the link correctly.

Conclusion

And there you have it! With these step-by-step instructions, you should now be able to configure universal/deep links like a pro.
