How can support for deep links be implemented in a mobile application?

Deep link support in a mobile app on Android is implemented through configuring Intent filters in the manifest and handling the received data in the activity.

Main steps:

1. Add an Intent filter in AndroidManifest.xml for the activity that should open via the link. For example:

<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="https" android:host="example.com" android:pathPrefix="/product" />
</intent-filter>

2. Handle the Intent in the activity to extract parameters from the URI and perform the necessary actions:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Intent intent = getIntent();
    Uri data = intent.getData();
    if (data != null) {
        String productId = data.getLastPathSegment();
        // load product data by productId
    }
}

3. For more complex scenarios, you can use App Links with domain verification or third-party libraries for navigation management.

Thus, deep links allow users to navigate directly to a specific screen of the app from external sources.
