If you are using IntelliJ IDEA or Android Studio:

Go to Settings > Editor > General >Auto Import and check the Optimize imports on the fly checkbox.

File/Settings/Inpsections/Imports and change "Unused import" to Error. This marks them more clearly in the Inspections gutter and the Inspection Results panel.
