error when running the app in android studio: "is not a valid file-based resource name character"

  • 772

well, the app just didn't want to run anymore, and this is the code that comes out, I already tried to REDO all the fragments (that's what I did and still nothing)

Error:Error: 'C' is not a valid file-based resource name character: File-based resource names must contain only lowercase a-z, 0-9, or underscore
Error:Execution failed for task ':app:mergeDebugResources'.

    Your error message specifies the problem:

    Error:Error: 'C' is not a valid file-based resource name character: File-based resource names must contain only lowercase az, 0-9, or underscore

    Your resources must contain names with lowercase letters with characters from "a" to "z", they can contain numeric characters from "0" to "9", and underscore , rename your layout:

    fragment_Calendario.xml

    a

    fragment_calendario.xml

    Also check if you have more incorrectly named resources besides this layout to avoid problems.
