App Indexing through mobile application

Question

I have used this Firebase Tutorial URL <https://firebase.google.com/docs/app-indexing/android/public-content> for integrating App Indexing in my Android and iOS application.

I reviewed the sample application provided and it is working fine, but when I am integrating it in my application, but in my AndroidManifest.xml I got confused with this following code snippet:

 <data android:scheme="http"
                android:host="recipe-app.com"
                android:pathPrefix="/recipe" />

My questions are:

• What is recipe-app.com and pathPrefix, what are the things I need to do to make App Indexing work in my application?
• Is there any descriptive tutorials for Integrating App Indexing in Android apart from Firebase official link?
• Where should I put digital assets link file on the server?

Answer 1

 <data android:scheme="http"
                android:host="recipe-app.com"
                android:pathPrefix="/recipe" />

This is how you declare that you app handles certain URLs. The idea is that App Indexing builds on top of app links, which are a way of having your app handle regular web URLs.

So if your app is "MyApp" and you have "myapp.com" you would change the android:host value to "myapp.com". The path is for if your app only handles a subset of the paths on your site. For example, if you have a forum under /forum and a pricing calculator under /calculator and your app only implements the calculator, you would use:

 <data android:scheme="http"
                android:host="myapp.com"
                android:pathPrefix="/calculator" />
