问题
My jni folder in Eclipse looks like this:
It is grayed out and has a diagonal line across it. What does it mean? I can still edit my native C++ code in this folder and see the changes as I test the application.
回答1:
It means the directory is being filtered from the source locations. It seems you can use this to exclude files that are not source from a source folder, although I've never used it.
I got rid of this irritation in Eclipse Indigo CDT by:
(Project) Properties ->C/C++ General ->Paths and Symbols ->Source Location Tab ->Edit Filter... ->Remove
回答2:
You probably have something in the folder that is deprecated.
