title: RxJava and RxAndroid - Do I need both?
body: <p>There's a similar question <a href="https://stackoverflow.com/questions/36182269/combination-of-rxjava-and-rxandroid">here</a>, but it doesn't really answer the question.</p>
  
  <p>I've been using RxJava and RxAndroid in my Android application, and now the project works.</p>
  
  <p>Then I removed RxJava and only left RxAndroid, and the project continues to work.
  However, I don't know enough about RxJava and RxAndroid to know if leaving just RxAndroid would be missing things in the long run.</p>
  
  <p>Everything I read about RxAndroid is that it is an extension of RxJava, but is this a true extension in the sense of having everything RxJava has + some Android specific stuff (like AndroidSchedulers)?</p>
  
  <p>Would I need both anyways? Are there downsides of keeping both dependencies?</p>
  
  <p>Thank you.</p>
