I'm having issues with Camera2API's SIGBUS in debug mode on Android OS 14. Has anyone experienced the same problem or knows how to resolve it? I did the following to check the event:
- This occurs when running an app that uses Camera2 and Native code in debug mode. (Or change the debug type to (Java + Native))
https://developer.android.com/studio/debug?hl=en#debug-types
This issue occurs in debug mode on Pixel 7a and Pixel Tablet with Android OS14. SIGBUS did not occur on the Galaxy S9, a slightly older model equipped with Android OS 10.
The development environment is Android Studio HedgeHog Gentoo Linux. (I have two PCs, and the same problem occurs even if I switch between development machines.)
I thought the problem might be with the preview View object, so I also tried TextureView and SurfaceView, but the results were the same.
I don't think this problem occurred on Android OS 13.
I tested it with Camera2 API using the simplest possible code and the result was the same. (A similar phenomenon occurs in the sample code.)
Below is the trace shown when debugging.

Since I want to process camera input data with OpenGL, I would like to use Camera2 if possible.
If anyone knows, it would be helpful if you could share the information.
thank you.
