mah thanks for your reply
1 I checked in /data/data/mypackage/libs
my library is present in the above folder
Second aproach you suggested me is
I am able to work with ndk tools
I observed both libraries that mean one my build and second one is
through ndk tools
i used nm tool to see what is in it.
But i did not understand any thing i am pure in this terminology
i am pasting the nm tool out put can u suggest any thing
Thanks in advance.
# nm libmylib.so //using arm tool chain
