Hello,

I tried to import sample android project into Eclipse. But I get an error. All android lib are missing

import org.opencv.android.BaseLoaderCallback;
import org.opencv.android.LoaderCallbackInterface;
import org.opencv.android.OpenCVLoader;
import org.opencv.android.CameraBridgeViewBase;
import org.opencv.android.CameraBridgeViewBase.CvCameraViewListener;
import org.opencv.android.JavaCameraView;

Where can I find this lib? I can run OpenCv Java project, but I don't know why android lib are missing.

Can some one help me.

Thanks

You probably didnt download any android api yet. Go to your android sdk folder. Then go into tools and start the android sdk manager, on linux just with ./android. On windows it should be an exe. With this you can download the correct android api level (18 = android 4.3, 17 = android 4.2 and so on). Make sure you also have build and platform tools installed. Then you should also be able to use android examples.

Did you add the opencv library to your workspace? Did you add the library to your project in the project settings? http://imgur.com/a/cKEN0

Yes, I tried. But there is no library in opencv-2.4.6.1 in sampels (not in others folders). So I can add it. This is the problem. I relay need help.

I folow all instructions from official tutorials

The library is in opencv-android-sdk/sdk/java. You need to import the library as a project.

It seems like you downloaded the wrong opencv sdk. Here is the one for android: http://sourceforge.net/projects/opencvlibrary/files/opencv-android/2.4.6/OpenCV-2.4.6-android-sdk-r2.zip/download
