title: How to import the AOSP apps (launcher, contacts,...) into Android-Studio?
body: <h2>Background</h2>
  
  <p>Google has <a href="https://android.googlesource.com/" rel="noreferrer"><strong>a website</strong></a> for all of the AOSP apps here, which includes its launcher, contacts etc...</p>
  
  <h2>The problem</h2>
  
  <p>I'd like to know how to import those apps. More specifically, <a href="https://android.googlesource.com/platform/packages/apps/Launcher3/" rel="noreferrer"><strong>the launcher</strong></a> and the <a href="https://android.googlesource.com/platform/packages/apps/Contacts/" rel="noreferrer"><strong>contacts</strong></a> apps (though I'd also like to know about others too).</p>
  
  <p>Thing is, it's not that simple. You can't just import the cloned project and that's it. Even if you use Eclipse (which seems like the official tool used on those repositories, according to the folders hirerchy ) it doesn't work as easily.</p>
  
  <h2>What I've found</h2>
  
  <p>I've found an <a href="https://chislonchow.wordpress.com/2014/04/12/android-launcher-3-build-from-eclipse-from-4-4-2-source/" rel="noreferrer"><strong>old post</strong></a> regarding how to import the launcher (version 4.4.x) , but it's using Eclipse and I think require Linux to build some files.</p>
  
  <p>I've tried to import using Eclipse, but for some reason I couldn't get to use a working "protobuf" library. I've tried to use a jar from <a href="http://mvnrepository.com/artifact/com.google.protobuf/protobuf-java" rel="noreferrer"><strong>here</strong></a>, but it didn't succeed importing it. </p>
  
  <p>There is also a <a href="https://github.com/chislon/Launcher3" rel="noreferrer"><strong>nice third party library</strong></a> that has an imported version of the launcher app, but currently it's a bit behind as it's based on Kitkat (4.4) and not Lollipop (5.0) .</p>
  
  <h2>The question</h2>
  
  <p>How do you import those projects? Is there an easy way? Would it work even on Windows OS and Android Studio ? </p>
