I plan to make this method `public static` so that it can be tested directly.
This method doesn’t depend on the handler instance, and doing so will allow the test class which currently has no package declaration to invoke it.
Please let me know if you have any concerns.

Also, sorry for the long messages: this is my first contribution and I’m trying to be thorough.
