Note: To avoid unintentionally extending the lifetime of the provided context, the actual observer registration is performed using the application context (or a user-specific context derived from it), rather than holding a strong reference to the provided context. However, the user ID of the provided context is preserved to ensure the correct user's settings are monitored. As a fallback, if the application context is null (which typically only occurs in mocked contexts during tests or during very early process initialization), the provided context is used directly. Callers should ensure that in this fallback scenario, the provided context is not an Activity or other short-lived context, as it may result in extending its lifetime indefinitely if the returned runnable is kept alive.
