Android Question Error reading Boolean value from map.

Hi. I have a key dimmed as Boolean and a value of False in a text file that I read as a map when my app starts. This approach has worked well for saving and getting settings that are strings and numbers, but when I do it with a Boolean key and value, I get the error message java.lang.RuntimeException: Cannot parse: False as boolean. Do I need to use an INT or String instead for the storage and then do some conversion with IF THEN when reading?
