title: A complete list of all Android project.properties options
body: <p>I only know the following properties and I would like to have a complete list.</p>
  
  <p>This specifies the target API level (API level 17 in the example):</p>
  
  <pre><code>target=android-17
  </code></pre>
  
  <p>This specifies whether the project is a library:</p>
  
  <pre><code>android.library=true
  </code></pre>
  
  <p>This specifies the included libraries in the Android way (directories of the library projects are merged into the including project's corresponding directories):</p>
  
  <pre><code>android.library.reference.1=../relative/path/to/library/one
  android.library.reference.2=../relative/path/to/library/two
  ...
  android.library.reference.n=../relative/path/to/library/n
  </code></pre>
  
  <p>This specifies whether the manifest file (<code>AndroidManifest.xml</code>) of the library projects are merged into the including project's manifest file:</p>
  
  <pre><code>manifestmerger.enabled=true
  </code></pre>
  
  <p>I saw the first three in my projects (generated by Eclipse) and found the last one from <a href="http://developer.android.com/tools/sdk/tools-notes.html" rel="nofollow noreferrer">SDK Tools - Revisions - SDK Tools, Revision 20 (June 2012)</a>, which is very difficult to find.</p>
  
  <p>Would there be a complete list in the official site / documentations / Android source?</p>

  <p>Thanks to <a href="https://stackoverflow.com/users/878126/">android developer</a> who reminded me the <code>proguard.config</code> property, which is left commented in the default <code>project.property</code> file.</p>
  
  <p>This specifies the path to the <a href="http://developer.android.com/tools/help/proguard.html" rel="nofollow noreferrer">ProGuard</a> configuration file:</p>
  
  <pre><code>proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
  </code></pre>
  
  <p>Two variables are available: <code>${sdk.dir}</code> and <code>${user.home}</code>. More information could be found in the <a href="http://developer.android.com/tools/help/proguard.html" rel="nofollow noreferrer">ProGuard Documentation</a>.</p>
