Registering Android deep link path without including subdomains

Question

I am trying to create a deep link to match a URL specifically on the specified domain, and not on any subdomains. My intent filter <data /> entry looks like this:

<data
  android:host="example.com"
  android:pathPrefix="/somepath"
  android:scheme="https" />

This works fine, and matches URLs with https://example.com/somepath as I'd expect. However, there are also URLs that I have that look like https://subdomain.example.com/somepath that I do not want to match. These are picked up by that data entry as well!

I want to match STRICTLY on the host and not include any subdomains. Is this possible in Android?

It's not possible to change the URL scheme for either set of links.

Answer 1

As I see in the documentation, your configuration will not match with subdomains.

If you want to accept all subdomains you have to use an asterisk (*) character before your host like this: *.example.com.

So, the answer is: example.com will not match with any subdomains like subdomain.example.com

I have created and Activity with the following intent-filter

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

This opens test.example.com in a browser window:

adb shell am start -a android.intent.action.VIEW -d "https://test.example.com/somepath/test"

This opens my application:

adb shell am start -a android.intent.action.VIEW -d "https://example.com/somepath/test"
