NoClassDefFoundError When Debug Android Engine Connected Android Project
<p>I’m struggling on a problem on my new Android C2DM test project: 
<strong>Android Engine Connected Android Project.</strong> 
The problem is:</p>

<p>At LogCat:
 <strong>04-04 19:35:09.414: E/AndroidRuntime(320): java.lang.NoClassDefFoundError: 
com.google.android.c2dm.C2DMessaging</strong></p>

<p>Location at debug window:  <strong>InvocationTargetException.class</strong>
InvocationTargetException.(Thrownable) Line 50</p>

<p>Exception: <strong>NoClassDefFoundError</strong></p>

<ol>
<li>Does any one have any idea what file (and where) I’m missing and how to fix?</li>
<li>Know where/how to get Google API source for debugging?</li>
</ol>

<p>Really appreciate your inputs. </p>
