I'm very new with using OpenCV Android. Few days ago, I've faced trouble with Static Initialization through the tutorial here: http://docs.opencv.org/doc/tutorials/introduction/android_binary_package/dev_with_OCV_on_Android.html When I run my code on device, the Logcat comes out with this debug line:
First attempt to load libs fails I've tried bunch of solutions such as: - Add line mOpenCVCallBack.onManagerConnected(LoaderCallbackInterface.SUCCESS); to OnCreate() - Copy OpenCVAndroid/sdk/native/libs/ to Project/libs/ - ... Didn't work for me. Any of you has taken over it? Please help Here is my java file: import java.io.ByteArrayOutputStream; import java.io.File; import java.io.FileOutputStream; import java.io.IOException;
