title: Android App Class Not Found Error
body: <p>I developed an Android project in the package:<code>com.anand.eprint</code>. </p>
  
  <p>The package contains <code>ePrintActivity.java</code> and <code>GmailSender.java</code>. The <code>ePrintActivity</code> calls <code>GmailSender</code> internally. This is working successfully. </p>
  
  <p>I exported the project, taken backup and formated the system. 
  Now I installed new OS, eclipse and android environment. </p>
  
  <p>Imported the same Android project into eclipse. </p>
  
  <p>Now I am trying to install and run in <code>Emulators/Android</code> Phones. </p>
  
  <p>I am getting error: <code>ClassNotFoundError:GmailSender</code>. </p>
  
  <p>Please anyone help me ?</p>
