Something wrong about Hashmap. But I can't replaced

Please help me. Now i try to get database from SQlite, It is something wrong. But I can't fix

"Explicit type argument HashMap<String, String> can be replaced with <> This inspection reports all new expressions with type arguments which can be replaced with diamond type <> Such <> syntax is not supported under Java 1.6 or earlier JVMs."

This is my picture.
