You forgot to copy the library files of OpenCV. Please read the README.txt 
file. If you are having problems /using/ JavaCV, please post on the mailing 
list.

I follow the instructions "Quick Start for OpenCV" for Eclipse (Android 2.2).
I download OpenCV-2.2.0-android.zip and I have put it libs/armeabi. Thats is 
correct?

Thanks!

In the readme.txt says:
·OpenCV 2.2 http://sourceforge.net/projects/opencvlibrary/files/
     *Precompiled for Android http://code.google.com/p/javacv/downloads/list
I need install OpenCV 2.2 or just install the library precompiled for Android 
(OpenCV-2.2.0-android.zip)?

Where does it say in the README.txt file that you need to install OpenCV 2.2 
for Mac OS X to use it under Android?

Hi,
I'm, so confused.
I have folloewd de instructions:
Eclipse (Android 2.2 on ARMv7 or newer versions):

Follow the instructions on this page: 
http://developer.android.com/guide/tutorials/hello-world.html
Go to File > New > Folder, select your project as parent folder, type 
"libs/armeabi" as Folder name, and click Finish.
Copy javacpp.jar and javacv.jar in the newly created "libs" folder.
Extract the *.so files from javacv-android-arm.jar as well as the *.so files of 
OpenCV in the newly created "libs/armeabi" folder.
Navigate to Project > Properties > Java Build Path > Libraries and click "Add 
JARs..."
Select both javacpp.jar and javacv.jar from the newly created "libs" folder.

I need to install or do anything else?

That should work if you have an ARMv7 CPU, but the emulator does not do ARMv7, 
only ARMv5. Please refer to issue #60
