Deeplink empty path error: "android:path cannot be empty"

Question

I'm trying to configure deeplinks for my app. I configured several options like:

https://myapp.com/news       --->     NewsActivity
https://myapp.com/history    --->     HistoryActivity

with intent filters like:

<intent-filter android:label="MyApp">
 <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="myapp.com"
       android:pathPrefix="/news" />
</intent-filter>

and

<intent-filter android:label="MyApp">
 <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="myapp.com"
       android:pathPrefix="/history" />
</intent-filter>

I also want a link pointing from the base domain to my main activity

https://myapp.com   --->      MainActivity

I want the link to respond to the base domain but no to other links like: https://myapp.com/playlists since the playlist features is not currently implemented in the app and is better to redirect to the web.

But when I set the intent filter:

<intent-filter android:label="MyApp">
 <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="myapp.com"
       android:path="" />
</intent-filter>

I receive the following lint warning:

android:path cannot be empty

Ensure the URL is supported by your app, to get installs and traffic to your app from GoogleSearch.

Despite this warning, the behavior it is correct. How can I fix this warning?

Answer 1

Had the same issue, you can just ignore the warning with tools:ignore="AppLinkUrlError"

So your intent would be:

<intent-filter android:label="MyApp">
 <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="myapp.com"
       android:path=""
       tools:ignore="AppLinkUrlError" />
</intent-filter>

Add xmlns:tools="http://schemas.android.com/tools" to your initial manifest tag if it's not already there.
