I'm using this library for scanning and cropping images but after publishing my apk in the google console developer I get this alert and the apk is rejected :
Libpng library The vulnerabilities were fixed in libpng v1.0.66, v.1.2.56, v.1.4.19, v1.5.26 or higher. You can find more information about how resolve the issue in this Google Help Center article.
I tried updating openCV to 3.1 but still get the same message.
Probably the problem comes from these because they're pre-compiled with an older version of OpenCV
\app\src\main\libs\armeabi-v7a\libopencv_java.so
\app\src\main\libs\armeabi-v7a\libScanner.so
If there's a way to re-compile these files and get the new .so I think it is the solution for that problem.
IDE : Android Studio
try this sollution i found it on OpenCV site:
