android -notlong eclipse: "Invalid resource directory name" -

-

i try refactor/rename layout/large forlder to

layout-xlarge-mdpi-notlong

then eclipse return error

invalid resource directory name

i don't understand why.

res/layout/my_layout.xml             // layout normal screen size ("default") res/layout-small/my_layout.xml       // layout small screen size res/layout-large/my_layout.xml       // layout large screen size res/layout-xlarge/my_layout.xml      // layout large screen size res/layout-xlarge-land/my_layout.xml // layout large in landscape orientation  res/drawable-mdpi/my_icon.png        // bitmap medium density res/drawable-hdpi/my_icon.png        // bitmap high density res/drawable-xhdpi/my_icon.png       // bitmap high density

supporting multiple screens

because -mdpi-notlong not supported in android.
