4. Error handling

Things are not always working as they should be. Several users report that get the following errors:

  1. Project ... is missing required source folder: 'gen'

  2. The project could not be built until build path errors are resolved.

  3. Unable to open class file R.java.

To solve this error select from the menu Project -> Clean.

If you having problems with your own code you can use the LogCat viewer as described in LogCat Viewer .
