title: Source of Android's lock screen
body: <p>I am looking for the source code of the android lock screen. It can be for any version of Android (1.5, 1.6, 2.0, etc).</p>
  
  <p>I tried looking in the repository at: <a href="https://android.googlesource.com/" rel="nofollow noreferrer">https://android.googlesource.com/</a>, but it doesn't look like it's under <code>platform/frameworks/base</code>. Maybe it's closed source?</p>
