Hi Tamman, Thanks for ur reply.
U wrote that "To compile any C application(customized lib is Bionic which contains cross tool chains, set of header files fordifferent libs etc.),we need NDK .. But JNI have its own syntax to write native code and to compile it. Then Why NDK? I m afraid whether i have wrong understanding .If So,Plz clarify my doubt .
