title: Proguard exception while creating release android apk
body: <p>I am building an app engine connected android project using the eclipse plugin. The project is working fine and so I decide it's time to create a release APK. Using eclipse, I go through the process. But when I reached the end, I get an exception: <code>Proguard returned with error code 1</code>. I include the entire log below.</p>
  
  <p>My GEP generated project comes with two proguard related files: <code>proguard-google-api-client.txt</code> and <code>proguard-project.txt</code>. There is also a project named proguard but it's empty. The <code>project.properties</code> file has two lines in it</p>
  
  <pre><code>proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt:proguard-google-api-client.txt
  target=android-17
  </code></pre>
  
  <p>Will someone please help. Other than these proguard errors my code is working fine. I test in emulators and real devices. That never paused a problem in development. Also my backend is already deployed on app engine and I have no trouble using it with my dev api. </p>
  
  <p>After some reading, I landed on <a href="https://stackoverflow.com/questions/5013163/how-can-i-check-upgrade-proguard-version-whn-using-it-in-eclipse-for-android-dev">How can I check/upgrade Proguard version whn using it in Eclipse for Android development?</a>. But after I manually update proguard from 4.7 to 4.9, when I try to export an apk I get the eclipse error that it cannot find the file <code>android-sdk-macosx/tools/proguard/proguard-android.txt</code>.</p>
  
  <p>EDIT: Based on feedback I receive, I created the following file called <code>proguard-mine.txt</code></p>

  <p>And then edited <code>project.properties</code> as</p>

  <p>But after the run, I still get the errors. Will someone please give me a hint on what my file is missing? I get the errors if I remove the <code>#</code> as well.</p>
