StrictMode reports that the local rs object leaks memory if it does not call destroy() on the local reference. Always calling destroy() explicitly (when not null) fixes this memory leak.

E/StrictMode: A resource was acquired at attached stack trace but never released. See java.io.Closeable for information on avoiding resource leaks.
