Can another developer extract and reuse my native

Question

I am creating a native plugin to use with my cordova app for some security specific functions (encryption / decryption etc). Can another developer extract the plugin from my app and use it ?

This is my first cordova app, so I don't fully understand how everything works yet.

EDIT: In iOS - I will write the plugin in C++ & Objective-c In Java, I will use JNI to access the C++.

Will the C++ source be viewable ?

Yeah, i have not done it myself but im pretty sure you can extract any apk file

e.g. how to extract code of apk file

e.g. http://www.decompileandroid.com/

I know that developers can create a "shell" of an app that once is downloaded will then dynamically download the rest of the app.

Hope it helps!
