Sample Programs compilation errors and warning

edit

Hi-

I have ADT and open CV with NDK. After importing all the projects and setting up the library links, I have following errors and warning-

1. case expressions must be constant expressions - CameraCalibrationActivity.java
2. Description Resource Path Location Type Invalid project path: Include path not found (C:\sdk\native\jni\include). OpenCV Tutorial 2 - Mixed Processing pathentry Path Entry Problem Invalid project path: Include path not found (C:\sdk\native\jni\include). OpenCV Sample - face-detection pathentry Path Entry Problem Invalid project path: Include path not found (C:\sdk\native\jni\include). OpenCV Sample - native-activity pathentry Path Entry Problem

I have already updated Android.mk file with the path (C:/OpenCV4Android/OpenCV-2.4.9-android-sdk/sdk/native/jni/OpenCV.mk) where I installed SDK.

I will appreciate your input.

Thanks in advance!
