It just means the data has to be saved in the provider earlier than
onPause ("cancel" in this context). The pattern sometimes results in
tiny content provider updates where the performance hit is an issue
I'm still learning about. They key, that "When you are saving your
data you are storing it in a content provider, not returning it as a
result" is subtle yet instructive.
Thanks!
