title: Android ICS version building contacts code on eclipse
body: <p>I am trying to build ICS contacts code on eclipse. As contacts was using some hidden classes, I created a new jar file with all the required classes and was successful in building the apk. </p>
  
  <p>But now the problem is the classes whichever I added in the jar are missing links in the final apk package and I am getting noClassDefFoundError exception.</p>
  
  <p>I decompiled the apk and found that class was present in the apk. Why the link is missing eventhough class file is present in the apk?</p>
  
  <p>I tried using the jar file as an external library but because of its size (>20mb) was not successful.</p>
