I am having trouble figuring out how to go from a string back into the list array. 

I currently have a list array to go into a string like the following:

```
String joined = TextUtils.join(",", blacklistedpins):

```

I have that to send the string into a database. However now when I want to read that string from the database I need to take it and put it back into the list array. How would I go about doing this?
