  </code></pre>
  
  <p>**project.properties : **</p>
  
  <pre><code># To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
  proguard.config=proguard.cfg
  
  # Project target.
  target=android-17
  android.library.reference.1=..\\librarySlideMenu
  android.library.reference.2=../google-play-services_lib
  </code></pre>
  
  <p>Please tell me about the solution to that and how to do exactly the setting of proguard.</p>
  
  <p>Thanks in Advance.</p>
