title: Proguard seems to have not effect / not to run when exporting Android app in Eclipse
body: <p>I am about to release an Android app and would like to use Proguard to obfuscate the code. I did everything as described in <a href="http://developer.android.com/tools/help/proguard.html" rel="nofollow">Googles Proguard Guide</a> but Proguard seems not to run:</p>
  
  <p>This is what I did:</p>
  
  <ol>
  <li>The guide says, that a <em>"proguard.cfg file is automatically generated in the root directory of the project"</em> There is no such file in my project-root but a <code>proguard-project.txt</code>file. I assume that this is the confic file the guide is talking about.</li>
  <li>I made no changes to the <code>proguard-project.txt</code>file. Thus Proguard should apply to all class names, etc.</li>
  <li><p>I edited the <code>project.properties</code> and uncommented the <code>proguard.config=...</code> line:</p>
  
  <p><code>proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt</code> </p></li>
  </ol>
  
  <p>According to the guide this should be all that is necessary to configure Proguard. All that is not necessary to run Proguard is to build the app in <code>Release mode</code>. </p>
  
  <p>I don't know how to munally run the app in <code>Release mode</code> but as the guide says this is done automatically when the app is build using the 'File/Export/Export Android Application` menu.</p>
  
  <p>So, I exported the app to create the APK. The guid says that Proguard creates several files and folders in the project dir everytime it runs, e.g. <code>dump.txt</code>, <code>mapping.txt</code>, etc. But none of these files is created. Additionally there is no output in the consosole or the log. Thus I assume that Proguard did not run.</p>
  
  <p>Is there a (easy) way to test if the file was obfuscated / if Proguard did run? What else to I have to do, to make Proguard work?</p>
