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

Change your image name as bg_main for all. It will do.

You cannot use capital letters or - in drawable image name. Just try to rename your image as bg_main and your problem will be solved.

Use _ instead of -. So, your drawable should look like this bg_main/ P.S: never use - in XML naming
