As instructed in the README.txt file, have you also copied the native libraries 
of JavaCV from javacv-android-arm.jar?

am assuming the javacv-android-arm.jar is the one under 
javacv-bin-20120329.zip, therefore all i did, was extract all the files and 
save them under libs/armeabi as instructed

You're missing the libjni*.so files from the javacv-android-arm.jar archive. 
Please try to extract those as well...

am sorry if this sounds lame but where do i get javacv-android-arm.jar archive? 
it is not under the http://code.google.com/p/javacv/downloads/list....and the 
one i have from
javacv-bin-20120329.zip (do not know if this is the right one) cannot be 
extracted further once iv extracted the javacv-bin-20120329.zip into these 
files:
javacpp.jar
javacv.jar
javacv-android-arm.jar
javacv-linux-x86.jar
javacv-linux-x86_64.jar
javacv-macosx-x86_64.jar
javacv-windows-x86.jar
javacv-windows-x86_64.jar

this javacv-android-arm.jar file cannot be extracted further

Then get something that can! Under Windows where Microsoft only seems to be 
able to bundle lame tools with their OS, we can use 7-Zip http://www.7-zip.org/

I am guessing you were able to get it running, but please ask your questions on 
the mailing list if possible if you still have some problems, thank you
