Looks like a problem with OpenCV 3.0... Does this happen with any other version?

[tomerhatav]

No, only with OpenCV 3.0

[baole]

How can we change to older OpenCV version?

EDIT: I switch to javacv ver 0.8 and it still crashes.

[saudet]

I found that the problem is probably caused by OpenMP, as explained in the last commit noted above. I've placed a new set of binaries here that should fix this issue:
https://oss.sonatype.org/content/repositories/snapshots/org/bytedeco/javacpp-presets/opencv/3.0.0-1.0.1-SNAPSHOT/
They work fine in the Nexus 5 emulator here, but let me know if they still do not work for you, and thanks reporting!

[saudet]

The builds for version 1.1 work properly, so please use that! And thanks for reporting.
