When I open eclipse it R class disappears in my project. Why? I have eclipse juno and latest android SDK.
R class
R class not recoverable because there are errors in the code ... How can I solve this problem?
Try Project → clean
if that fails, fix the errors and build the project again, it R class will regenerate.
Have you tried to rebuild the whole project? You can do this using the Project → Clean menu item.
Look for errors in XML resources; this will prevent the creation of R as well as errors in the code.
The Errors tab in Eclipse is your friend here.
Clean the project and rebuild it
Build / cleanup project
Build / rebuild project
in android studio
Thank you
