title: How to override a class within an Android library project?
body: <p>The following is my situation: </p>
  
  <p>I have a library project and a project based on it.  Now in the library I have two classes A and B, whereby A uses B. In the project using the library, I have another class B, which should override the class B from the library.</p>
  
  <p>But every time class A makes a call, it ends up in the class B from the library.
  How can I tell Android that class B from my project should be used INSTEAD of class B from the library?</p>
