出现错误错误：res / menu / mainMenu.xml：无效的文件名：必须仅包含[a-z0-9_。]

Question

I am new to android and just started it. I created a file in res folder, menu/mainMenu.xml. But i got the error

Error: res/menu/mainMenu.xml: invalid file name: must contain only[a-z0-9_.]

When i changed the file name to just mainmenu(remove the capital M) then it started working. Why? I am using intelliJ 10.5.1.

Thanks

Answer 1

xml file doesnot support capital letter in naming of xml file so try removing capital letter.

correct mainmenu.xml or main_menu.xml . For further detail you can look onto this .

Answer 2

it should be mainmenu.xml ,no capital letter is allowed in naming of xml files.

  File name must contain only lowercase a-z, 0-9, or _.

• only az ,mind that not capital...and white-space not allowed

• name must start with a character.not with a Number(0-9)

• name only _ symbol allowed.no other symbol alowed.
