Error: Unable to open class file R.java and How to fix it.





[2011-05-27 12:12:39 - listActivity] ERROR: Unable to open class file /root/workspace/Manifest.java: No such file or directory

R.java and Manifest.java is a automatically generated file.


The ADT has a few such annoying bugs. But you can sort them out..
What usually helps is:



1. Close Project->Open Project > Build Automatically .
2.Another thing that sometimes helps is right click project > android tools > fix project properties and remove unnecessary content or jar files.

3.Or you can do Project->clean and Refresh .




If still it not generating R.java files then check your class there must be a extra line..

Import R.java.*; Remove that and then do all the above one by one..

Hope it help ..

If someone know other way please let me know.

Thanks
