title: Proguard Android using Action Bar Sherlock
body: <hr>
  
  <p><strong>EDIT 4:</strong>
  I've tried taking out Action Bar Sherlock and Proguard did it ok. So I guess it is a problem with android-support-v4.jar.</p>
  
  <p>I tried this when including the ABS library, but it didn't work..</p>
  
  <pre><code>-keep class android.support.v4.app.** { *; }
  -keep interface android.support.v4.app.** { *; }
  -keep class com.actionbarsherlock.** { *; }
  -keep interface com.actionbarsherlock.** { *; }
  
  -keepattributes *Annotation*
  </code></pre>
  
  <p>Finally, What is weird is that I tried without the <strong>ABS library and without proguard-android.txt</strong> and it worked as well.</p>
  
  <p><strong>I have no clue of what the problem is.</strong></p>
  
  <hr>
  
  <p>I've read tons of Q/A about this and tried many solutions but none worked out.</p>
  
  <p>I've tried doing:</p>
  
  <pre><code>-injars libs/**
  </code></pre>
  
  <p>And:</p>
  
  <pre><code>-libraryjars  libs/**
  </code></pre>
  
  <p>And other things that didn't work..Could you give me your opinion on what I should do?</p>
  
  <p><strong>I am using 4 external jars:</strong> </p>
  
  <ul>
  <li>apache-mime4j-0.6.jar   </li>
  <li>httpclient-4.2.2.jar</li>
  <li>httpcore-4.2.2.jar</li>
  <li>httpmime-4.2.2.jar</li>
  </ul>
  
  <p>This is error console when I tried to export the signed apk:</p>

  [2013-10-15 18:36:12 - ExampleProGuard]       You should check if you need to specify additional program jars.

  [2013-10-15 18:36:12 - ExampleProGuard]          You may need to specify additional library jars (using '-libraryjars').

  <p><strong>EDIT</strong></p>
  
  <p>First, thank you Eric for your answer.</p>
  
  <p>I tried:</p>
  
  <pre><code> -dotwarn org.apache.common.**
  </code></pre>
  
  <p>and</p>
  
  <pre><code> -dontwarn org.**
  </code></pre>
  
  <p>But it shows the exact same console errors.</p>
  
  <p>I saw this <a href="https://stackoverflow.com/a/10967049/1598935">thread</a> so I tried adding a new classpath variable with the path to sdk but it shows the same console errors.</p>
  
  <p><strong>This is my project.properties file where it refers too to the Action Bar Sherlock</strong></p>

  </code></pre>
  
  <p><strong>EDIT 2:</strong></p>
  
  <p>As it says on Action Sherlock Bar <a href="http://actionbarsherlock.com/faq.html" rel="nofollow noreferrer">website</a> I tried this too without changing at all the error console:</p>
  
  <pre><code>-keep class android.support.v4.app.** { *; }
  -keep interface android.support.v4.app.** { *; }
  -keep class com.actionbarsherlock.** { *; }
  -keep interface com.actionbarsherlock.** { *; }
  
  -keepattributes *Annotation*
  </code></pre>
  
  <p><strong>EDIT 3:</strong></p>
  
  <p>I tried taking off the external jars (not ABS which is a library) from the project but it still shows the exact same error. I dont get where it is coming from.</p>
