title: Doclava cannot find symbol SystemProperties (Android javadoc)
body: <p>I am running doclava (javadoc with the Android-style doclava doclet) on an existing codebase. At this stage I'm using javadoc via a simple command line, so this is not an Ant or Eclipse issue. I've paths to what seem to be all the necessary JAR and source files and have closed off large number of warnings already.  The codebase itself builds and runs fine.</p>
  
  <p>However, I am left with some instances of one particular warning:</p>
  
  <pre><code>com.blah.blah.filename:42: error: cannot find symbol
  import android.os.SystemProperties;
                   ^
    symbol:   class SystemProperties
    location: package android.os
  </code></pre>
  
  <p>Does anyone have any suggestions what I need to do to remove this last warning?</p>
