title: Developing for android, is there a way to cause eclipse to rebuild an app when only the source of its libraries was modified?
body: <p>I have an app that depends on a library I wrote. When I modify the code of the library and try to run the app it happily executes the old version of the app without checking to see if the library may be outdated. I find myself adding and erasing a space character in the app source to force the rebuild.</p>
  
  <p>Is there a way to fix this?</p>
