title: android cordova : cordova.exec() undefined is not a function
body: <p>I'm developing an android phonegap app using cordova(2.2.0). I've some custom phonegap plugins to make my app do some stuff. Now I'm facing a problem, sometime when I call :</p>
  
  <pre><code>alert(Cordova.exec(null, null, "custom", "setValue", localStorage.emailId));
  </code></pre>
  
  <p>*<strong><em>undefined value is getting popped in alert.</em>*</strong></p>
  
  <p>Here  I called <code>cordova.exec</code> after <code>deviceReady()</code> also.still not getting any value
  no exception in try-catch.
   also same for <code>PhoneGap.exec(....)</code></p>
  
  <p>I don't really understand why. Someone else experienced the same error?</p>
