if we use System.loadLibrary

System.loadLibrary("jniopencv_core");

System.loadLibrary("opencv_core");

System.loadLibrary("jniopencv_imgproc");

System.loadLibrary("opencv_imgproc");

it works properly

but other device give error

java.lang.UnsatisfiedLinkError: Cannot load library: soinfo_link_image(linker.cpp:1636): could not load library "libopencv_imgproc.so" needed by "libjniopencv_core.so"; caused by load_library(linker.cpp:746): library "libopencv_imgproc.so" not found

what should I do;

some device need loadlibrary and some not?

Yes, among other things:

Please report these bugs to device manufacturers.

But Javacv 1.1 and 0.9 have no bug.

How do you know? How many devices have you tested?

[Tarun Singhal]

10-15 device

SM-T231 

javacv 1.1 and 0.9 work without loadlibray

in javacv 1.2 need loadlibrary

Galaxy S Duos2

javacv 1.1 and 0.9 and 1.2 work without loadlibray

if use load library it crashes

If you do a "factory reset" on each device before installing anything, do you get the same result?

BTW, JavaCPP 1.2 has a known bug, If you are trying to use that version, you shouldn't use it:
    https://github.com/bytedeco/javacv/issues/412
Please try to use the latest version of everything and stop using old software when it's not needed!
