I've asked several questions about DeviceActivity performance issues where the answers have cited limitations to the lifecycle of the DeviceActivity App Extensions. For example:
-
Question about DeviceActivityReport lag and performance issues responded letting me know that my extension may be exceeding its memory limit of 100MB and subsequently getting terminated by the system.
-
Question about async tasks in DeviceActivityMonitor responded letting me know that the monitor extensions lifecycle ends and is terminated by the system once all synchronous functions return, so it has no async support.
I couldn't find either of these facts documented anywhere, and the DeviceActivity docs mention very little about how the extensions actually work. In general, it seems like these app extensions are basically a black box.
Is there any additional comprehensive documentation about the true lifecycle of the app extensions, their limitations, and how apps should handle error cases (like the system terminating the app extension process)? If not, I would be very grateful if you could provide any information you have in the response to this question. Thanks in advance!
