R在Eclipse中的Gen文件夹中丢失

Question

http://puu.sh/69sfM ~ Screenshot

I do not have a R file in my gen folder. I have gone through many different threads and none of the presented solutions have worked. I have even tried copying and pasting the R.Java file from a different project into this gen folder but when I clean & rebuild it automatically deletes the file.

Thanks for the help in advance.

Answer 1

Clean your project and run it.

Project ---> Clean then run

see this link it gives perfect solution for you..

Answer 2

Copying and pasting R from another project is WRONG.
R must be generated, always.

If it doesn't generate, some of your xml files contain errors (even small ones).
For instance, it can be a >> (double closing of a tag) or a wrong attribute name.
Look in EVERY xml file in your project, line by line, and you'll find the error.

Once I had this issue because of an error in strings.xml.
