This is kind of a followup to https://issuetracker.google.com/issues/141482822, comment #3.

There seems to be a bug related to the changes introduced in the aforementioned ticket. If I define a simple deeplink like so:

<deepLink
android:id="@+id/deepLinkToSomething"
app:uri="myapp://open/something />

... the deeplink will NOT be executed when I attempt to open an Intent which has the data URI myapp://open/something?someParameter=parameter. The solution to the aforementioned ticket should have made this work by ignoring undefined parameters.

My current local solution (as outlined per comment #3 in the aforementioned issue): adding a dummy parameter to the uri in the deeplink definition, like:

<deepLink
android:id="@+id/deepLinkToSomething"
app:uri="myapp://open/something?dummy={dummy} />

Then it works just fine.

I suspect it has something to do with how the pattern is compiled in the constructor of NavDeepLink in case there are no parameters.
