we tried the OpenCV Sample-face-detection from TADP and couldn't run it on Nexus 9. It works on Android-Devices lower than 5.

OpenCVManager: Device information

Tegra5 OS version: REL (5.0), API 21 Installed packaged Built-in OpenCV library(optimized) Library version: rev 1
Target hardware: Tegra OCV 2.4 pack armeabi-v7a (safe to remove)
Libray version: rev 1
Target hardware: arm7a

Error: Package not found OpenCV library package was not found! Try to install it?

If we click "yes" -> Page not found (in Play Store)

Has anyone an idea?

I'm having the same issue. Did you manage to solve it?

I have the same problem. I'm trying to run the same sample in my galaxy s6, which has an ARMv8-A architecture. I think this might be the problem. Also, the same thing happens when I try to click yes, it takes me to a page not found in play store. Don't know how to fix it yet... :(

I wonder if this is due to the fact that the Denver, which Nexus 9 has, is on ARMv8-A. I hope the next release of Android4OpenCV contains a pre-built binary for this architecture.

In the meantime, you could possibly build it by setting the target architecture as ''arm64-v8a" with this latest CMake toolchain file.

I didn't try it yet though, it would be helpful if somebody who tried this can share his/her experience. Thanks!
