title: java.lang.NoClassDefFoundError: com.amazonaws.auth.CognitoCachingCredentialsProvider
body: <p>I am running a sample of <a href="https://github.com/muneeb091/aws-sdk-android-samples/blob/master/CognitoSyncDemo/README.md" rel="nofollow">CognitoSyncDemo</a> and when i run my code on my device, my device gives an error "Unfortunately, CognitoSyncDemo has stopped." and eclipse Logcat gives an Exception</p>
  
  <p>java.lang.NoClassDefFoundError: com.amazonaws.auth.CognitoCachingCredentialsProvider</p>
  
  <p>Well i have checked the library, I have included</p>
  
  <p>aws-android-sdk-2.1.2-core.debug.jar
  extras/aws-android-sdk-2.1.2-cognito.debug.jar</p>
  
  <p>and if there is any library missing then eclipse should have given any syntax error, but there was none and it was raised as an exception.</p>
  
  <p>Please tell me what am i missing?</p>
  
  <p>Regards,
  Muneeb</p>
