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:         


        

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.
