Component used: Navigation
Version used: 2.0.0

When defining a deep link in the navigation graph, and exact match is required for parameter matching, with no possibility of marking parameters as optional, thus if only one parameter is omitted, all parameters will fail to be parsed.

This is especially troublesome when supporting many parameters or query configurations, as it isn't feasible to define each variation of parameter configurations.

Expected behaviour would be for NavDeepLink to enclose each parameter with an optional regex group, or to check the NavArgument for nullability.

Assigned to jb...@google.com.

A couple of questions:

1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?

Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

Marked as fixed.

Second crash in the description is from a real device. Experienced it myself on two different Xiaomi phones, plus lots of crashes from users in the Google Play console.
Dynamic features are not used in the application.

As a wild guess, I have downgraded build tools from 31.0.0 to 30.0.3, compileSdk from 31 to 30, and moved all work with Language ID to the service in a separate process (just to be sure that crash can kill secondary process instead of main). This combination is in beta for 2 days by now and I don't see any SIGSEGV crashes.

Hmm, I feel the crash might be something related to separate/secondary process.

I also changed compileSdk and targetSDK to 31 but still cannot repro this issue.

On the contrary, there was no separate process before, when crashes started.

In the new build (with the aforementioned changes) I can see SIGSEGV crash, but only one instead of dozens and it has a bit different backtrace:

signal 11 (SIGSEGV), code 1 (SEGV_MAPERR)
liblanguage_id_jni.so (offset 0x11e000)
