Fixing error message on Android build

• Adding keys to looped elements
• Reducing util import
• Resolves issue Build on Android not working #1

The issue was fixed by reducing the util import. The error message seemed to be pointing to an unused part of the util package. It could have instead been fixed within that package, but for now this will allow this component to be used by Android, and also somewhat reduce its size as it's not importing everything from util to call a single method.
