Error: ':' is not a valid resource name character

means that you have a resource name like

<string name="not:valid">Foobar</string>

but colon are not allowed.

Try this:

• Open your string.xml

• Type Ctrl + F (on Win/Linux)

• Check Regex and search by "[A-Za-z_]*:[A-Za-z_]*"

• Remove colon and if necessary replace with an underscore _

• Compile your apk
