Hi, I'd suggest you use the In-App purchase testing facilities Google provides - https://developer.android.com/google/play/billing/billing_testing.html - to test your theories about perceived failure scenarios.
When In-App purchases was initially introduced Google also recommended using your own (secure web) server to help keep track / verify some of purchase details as well. That's still mentioned at the end of - http://developer.android.com/google/play/billing/billing_integrate.html I found that useful as alternative to the 'journaling' you've suggested. I also attempted to (securely) store some of the details on the device itself as soon as they were received, but both of these approaches have their own issues - where you server is not available & where the user has multiple devices... In the end you just need to 'trust' the Google Play API's, but your own server can also help somewhat (with any disputes) by providing an independent transaction log even if it is sometimes incomplete.
