Android layout file and R are not synchronized to ensure effective

1. Select project> clean
The premise is to check bulid automatically (Automatic Build and deployment)
After you click clean, the project will be re-built, because in general, the R. Java file will re-update the generation side at this time. If the project is wrong, it will not be automatically generated.
2. Select a project, right-click Android tools> fix Project Properties

The above two solutions are provided on the network, but sometimes they still do not work. What should I do?

My method isIf the gen file is deleted, myeclispse will automatically generate the r file to synchronize the file.

If not, use the dumbest method. Create a new project, copy the layout file first, and then copy the code.

PS. If not, it indicates that your layout file is faulty. Check the layout file by yourself.
