title: How to browse Android source code at a particular version?
body: <p>I know that android source code is kept here: <a href="https://android.googlesource.com/" rel="nofollow noreferrer">https://android.googlesource.com/</a>, but I can't see any way to browse an old version of the code.<br>
  How would I view, say, <code>dalvik/libcore/concurrent/src/main/java/java/util/concurrent/LinkedBlockingQueue.java</code> in Froyo?</p>
