1. Have you saw crash in real device or only in simulators?
2. Do you use dynamic feature for language ID?
ch...@google.com <ch...@google.com> #3
Tested on Android 12 Emulator with custom executor, but cannot repro this issue.

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.
mo...@google.com <mo...@google.com> #5
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.
ch...@google.com <ch...@google.com> #6
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)

FYI, ML Kit launched a new language ID SDK in the latest release, which uses a new language ID model.
Could you try the new SDK version(17.0.0) to check if you can still repro this native crash? Thanks!
mo...@google.com <mo...@google.com>
mo...@google.com <mo...@google.com> #8
Thank you, I'll try it and check.

Hello. I have similar experience.
- I'm using mlkit-language 16.1.1
- I didnot meet this error until using AGP 4.2
- I can get this error since using AGP 7.0
- This error raised on Release build only(minimized by R8)
- This error raised without obfuscation.

Description
Currently I'm using
Modifier.onPositioned
a lot to know the laid out size of a node, butonPositioned
is wasteful for this, especially when it's in a scroller.Ideally I want just a
onSizeChanged
modifier to know only when the size changes.
