title: Redirect all network of Android App (which is using Libraries) through a proxy network (if available)
body: <p>I am working on an Android application and I am using various libraries like Picaso, Retrofit, Crashlytics, etc. and my college WIFI have proxy on it.</p>
  
  <p>I know how to use a proxy when sending a HTTP requests to a server, but all the libraries that I am using have there own HTTP requests, so overriding all their HTTP classes would be a headache, and I am not even sure how to do that.</p>
  
  <p>So, is there a way to route all the traffic of the App through a proxy (when available), like any library or some HTTP request overriding all the outgoing requests.</p>
