Android : Android Studio JNI: Loop of ClassNotFoundException

I'm creating a C++ Android APP based of the book Pro Android NDK and this tutorial (http://www.swig.org/Doc2.0/Android.html#Android_example_class)

I created a C++ class called Http that creates sockets to perform simple HTTP requests (mostly for learning purposes). The C++ app works on its own. I compiled it to JNI (using Swig) and generated the appropriate JNI code and the Java "proxy" files which I can use to call the code.

My original C++ constructor has this signature: Http::Http(const char * ip_address, int port)

1) In my AndroidStudio app I have an Activity called MainActivity. The Package containing the MainActivity and the generated JNI Java classes is com.zuzile. My default constructor looks like this SWIGEXPORT jlong JNICALL Java_com_zuzile_exampleJNI_new_1Http(JNIEnv *jenv, jclass jcls, jstring jarg1, jint jarg2) where "exampleJNI" is my Java class that contains the native method public final static native long new_Http(String jarg1, int jarg2);

2) After generating the appropriate JNI and corresponding Java classes I successfully compiled the JNI code into a .so file using NDK. I was able to load the .so file by calling System.loadLibrary("httpreq") httpreq is the name of my compiled module.

3) When I try to use my Module by calling Http("some IP address", "a port") I get the following error: java.lang.ClassNotFoundException: com.zuzile.MainActivity (as output by the Debugger).

If I remove the Http(...) declaration from my MainActivity.java my APP loads perfectly without crashing. But as soon as I use the Native code I generated it states it can't find com.zuzile.MainActivity.

I appreciate any help in advance as I've been stuck on this for 3 days now.
