title: Hide a library source code
body: <p>I am developing an android library and I want to hide it's code.
  I am using other library, and for some of them, when trying to access their code with Android Studio, you only get the list of methods of the class and "/<strong>* compiled code*</strong>/" inside.
  I am using pro-guard, but i can still access the source code of my library. Even if the methods and members names have been modified, the code is still readable and it is possible to read every hard coded strings.</p>
  
  <p>How do I hide my code the same way those libraries do ?</p>
