Hi,
I have just ran ndk-build for the code
https://github.com/aluvalassuman/OpenSSL1.0.1cForAndroid and
it generated the two shared libraries in libs/ floder which I required ,
libcrypto.so and libssl.so( as build say these are shared libarray) I just
included them in the curl code as prebuilt shared library(edited now
to shared in the android make) , then Since I need to include the curl
with openssl in my java code I want to build curl as shared library only
.. I just changed my android curl make to shared ..
And sorry it was System.loadLibrary("curltest"); only .. but still I'm
not getting the any response from the curl ...? am I following the correct
way to use the openssl , becoz when I test the curl alone I get the proper
http page requested ... !
Rgds
