Google's Gmail app for Android has remained an ad-free sanctuary, but code uncovered by Android Police in an APK teardown of the application's latest version hints that circumstances might change.

What's more, a "ShowAdPreferenceManager()" function routes users to the ad settings page for their very own Google account.
