ClassDefNotFound in Android

I've been jumping through hoops trying to include my utility jar in my project. Android documentation clearly states that all the import-via-filesystem should not be necessary (http://developer.android.com/resources/faq/commontasks.html#addexternallibrary) but I've tried all suggestions anyhow; putting in it a libs folder, clean the project, restarting eclipse.

Is there any way I can see how eclipse builds the project; I'd like to see that it actually tries to include my jar.

I was never able to solve the problem, but it seems to be caused by the Android cross compiler not being able to correctly process the generated Jar. As a work around I started copying the java files from the utility project into the Android project.

Build and Clean is not enough, you should add your jar file by configuring the Build Path. Follow these steps:

  • Right Click on your project
  • => Properties
  • => Java Build Path ( at left )
  • => choose the tab Libraries
  • => add jars
  • => specify your jar file that you have added it to the lib folder.

Hope it helps and sorry for my English

It seems that adding the jar to the build path isn't enough. You have to copy the jar to the project's folder (like to /libs).
