DP5 7.0 - Does adding extras to a pending intent fail?

So I installed the DP5 Android 7.0 rele

I have seen this sort of behavior reported before, with custom Parcelable objects and system services (e.g., NotificationManager). What seems to happen is that the system tries using the PendingIntent, and as part of that for some reason it tries to un-Parcel the Parcelable. This fails, because the system doesn't have your classes. I haven't heard of somebody running into this in a while, but it's entirely possible that there is a regression in Android N that re-introduced it.

You might rummage through LogCat to see if there are any messages — or, better yet, stack traces — from the system (not your app) that seem to pertain to your alarm event.

If you can create a reproducible test case, file an issue on the Android issue tracker. If you think of it, post a link to it here, as I'd like to take a peek at it.

In terms of workarounds, I can think of two:

1. Don't put the Parcelable in there. Instead, put an ID that you can use to look up the information as needed, whether from an in-memory cache (if your process happens to still be around) or from whatever your persistent data store is.

2. Switch from Parcelable to what I and others have termed "bundle-able", where you convert your object to and from a Bundle. Basically, stick solely to OS-defined classes, with no custom classes. Then, the system can safely de-Parcel the Bundle (for whatever reason it does so). This, of course, is much more painful than simply using an annotation processor to create the Parcelable implementation.
