Generic Android To Ios Deep Links

Code Patterns

URL Scheme Setup

Android (AndroidManifest.xml):

<activity android:name=".MainActivity">
    <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="myapp" android:host="open" />
    </intent-filter>
</activity>

iOS (Info.plist):

<key>CFBundleURLTypes</key>
<array>
    <dict>
        <key>CFBundleURLName</key>
        <string>com.myapp.scheme</string>
        <key>CFBundleURLSchemes</key>
        <array>
            <string>myapp</string>
        </array>
    </dict>
</array>

iOS (handling in SwiftUI App):

@main
struct MyApp: App {
    var body: some Scene {
        WindowGroup {
            ContentView()
                .onOpenURL { url in
                    // url == myapp://open/path?query=value
                    DeepLinkRouter.shared.handle(url)
                }
        }
    }
}

Verified Links (App Links / Universal Links)

Android (App Links - AndroidManifest.xml):

<activity android:name=".MainActivity">
    <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"
              android:host="www.example.com"
              android:pathPrefix="/items" />
    </intent-filter>
</activity>

Android (Server - /.well-known/assetlinks.json):

[{
    "relation": ["delegate_permission/common.handle_all_urls"],
    "target": {
        "namespace": "android_app",
        "package_name": "com.example.myapp",
        "sha256_cert_fingerprints": ["AA:BB:CC:..."]
    }
}]

iOS (Associated Domains entitlement):

# In Signing & Capabilities, add Associated Domains:
