OpenCV version: 4.5.4
Operating System / Platform: ChromeOS
Compiler AAR Android Studio version:Android Studio Dolphin | 2021.3.1 Patch 1
Unity version:Unity 2019.4.27f1 LTS
I developed an AAR using OpenCV 4.5.4 version in Android Studio for use in Unity.
My Unity output settings for 「Scripting backends」 were set to 「IL2CPP」,
and the 「target architectures」 were selected as 「ARMv7 and ARM64」.
However, when running the 「computeImageFeatures」 function of OpenCV on the 「ChromeBook ASUS C214M」 device, it crashes.
But if I select only 「ARMv7 」as the 「target architecture」,
it runs smoothly.
Additionally, on the following 64-bit CPU devices, the app with ARM64 selected as the target architecture runs without any issues:
- ChromeBook ASUS CM3000DVA
- Google Pixel 7
- Samsung Galaxy Note 8
- Samsung Galaxy Note 10
The models and CPUs of the tested smartphones are as follows::
- ChromeBook ASUS C214M: Intel® Celeron® N4000 Processor
- ChromeBook ASUS CM3000DVA: MediaTek 8183
- Google Pixel 7: Google Tensor G2
- Samsung Galaxy Note 8: Exynos 8895
- Samsung Galaxy Note 10: Snapdragon 855
I am Taiwanese, and I apologize for my poor English skills.
