title: How can I use external JARs in an Android project?
body: <p>I have created an Android project and added an external JAR (hessian-4.0.1.jar) to my project. I then added the JAR to the build path and checked it off in Order and Export.</p>
  
  <p>Order and Export is ignored it seems, and all classes from the external JAR are missing at runtime.</p>
  
  <p>Is there a trick to properly include the needed classes from an external JAR when building an Android application using the Eclipse plugin? I do not want to use ant or Maven.</p>
