CODE FRAGMENTS:
Use an example from

https://github.com/android/camera-samples/blob/master/CameraXBasic/app/src/main/java/com/android/example/cameraxbasic/fragments/CameraFragment.kt

and just change binding to this:

camera = cameraProvider.bindToLifecycle(
this, cameraSelector, preview, imageCapture, imageAnalyzer)
.apply { cameraControl.enableTorch(true) }

Status: Won't Fix (Intended Behavior)

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?

do...@gmail.com <do...@gmail.com> #3Mar 25, 2020 11:33AM

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

le...@google.com <le...@google.com> #4Mar 25, 2020 11:50AM

Status: Assigned (reopened)

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.

le...@google.com <le...@google.com> #5Mar 25, 2020 04:09PM

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.

le...@google.com <le...@google.com> #6Mar 29, 2020 05:20AM

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)

FYI, ML Kit launched a new language ID SDK in the latest release, which uses a new language ID model. https://developers.google.com/ml-kit/release-notes#august_11_2021

Could you try the new SDK version(17.0.0) to check if you can still repro this native crash? Thanks!

Marked as fixed.
