” In Java Build Path go to Order and Export and check all the checkboxes available. ” only worked for me after doing this, thanks!

ONE MORE Solution: None of the above ideas worked for me on 2 out of 3 projects that were exhibiting this problem. On one of the projects, Deleting gen and having it re-created by a Clean/Build operation worked fine. The other two projects, though, were still plagued. **THE SOLUTION**?: Right-Click “gen” folder in Navigator, Properties->Resource, UN-CHECK “Derived”, “OK”. Then delete R.java at the bottom of the “gen” tree, then rebuild.

deleting gen folder and rebuilding the project was helping me get rid of the error but that didn’t seem to be the solution. Thank you Christian for providing the solution.

Right click on project name in the package explorer. Go to properties. In properties go to Java Build Path. In Java Build Path go to Order and Export and check all the checkboxes available. That should solve the problem. Regards, Shomik.

Thanks for the tip! I even had to change from 1.6.0 to 1.6 in OS X in order to get it to work.

I changed the compliance level to 1.6 still it doesnt work. However manually creating gen folder solves the problem.

I installed the Eclipse/Android SDK/Java SDK with default settings.
I don’t have the “missing ….’gen’” problem until I moved some codes from other BlackBerry project. Before it, the Android codes build/run simulator without any problem.
The “editing code and save” and “delete ‘gen’ folder” doesn’t work for me.
But the “Delete the R.java file under the gen folder” does solve my problem.
