it is perhaps that the version of android-support-v4.jar is not right. solution:

  1. close the eclipse
  2. delete the android-support-v4.jar in the project's libs folder
  3. reopen the eclipse
  4. right click the project, Android Tools -> Add Support Library... then the eclipse will download the right version of android-support-v4.jar for your project and add it to your project.
  5. rebuilt and run your project, it will OK!

Given that you upgraded to r18, you might be having trouble with the changes to dependency management. See this link and this link for example.

Make sure you copy the compatibility jar file into your project's libs folder and add it to your build path.

If a libs folder does not already exist, create one off the root of your project.
