title: android-support-v7-appcombat jar mismatch and app crashing after Android 4.4 SDK update
body: <p>I have been successfully using android-support-v7-appcompat library for last few months in my app to support action bar in older devices. Recently I have downloaded the Android 4.4(kitkat) updates with system image and SDK platform from the SDK Manager. I also added targetSdkVersion to "19" in manifest file. But my project was showing error as 'android-support-v7-appcompat jar mismatch. Fix your dependaecies.' Then I added the jar from /extras/android/support/.... to the project as an external jar using build path menu > add external jar. Now there is no error in the project and android-support-v7-appcompat.jar &amp; android-support0v4.jar file is showing twice under 'Referenced Libraries' folder and also once under 'libs' folder. The project is not showing error and running, but crashing in different activities.</p>
  
  <p>Previously I imported the android-support-v7-appcombat library as an external project in the workplace. I can see error in that project. Please suggest what should I do now. Also,  android-support-v7-appcompat.jar umder Android Dependencies in Java Build Path showing error.</p>
  
  <p>The error I see is:</p>
  
  <pre><code>Found 2 versions of android-support-v7-appcompat.jar in the dependency list,
  but not all the versions are identical (check is based on SHA-1 only at this time).
  All versions of the libraries must be the same at this time.
  
  Versions found are:
  
  Path: C:\&lt;project hierarchy&gt;\libs\android-support-v7-appcompat.jar
  
  Path: C:\Users\....\sdk\extras\android\support\v7\appcompat\libs\android-support-v7-appcompat.jar
  
   Jar mismatch! Fix your dependencies
  </code></pre>
  
  <p>After getting idea from different forum, I removed all the android-support-v7-appcompat libraries from different places, and imported android-v7 support library again in the project. Still it's showing error. Should I also delete android-support-v4 libraries from buildpath and libs/private librariry/referenced library folders? </p>
