Yeah, OK, that update took a while. 2020 has been very odd.

The existing material was updated to reflect R Beta 3. This includes significant changes to the chapter on scoped storage.

Also, the chapter on bubbles was overhauled to be a chapter on conversations and bubbles, since now those two concepts are very closely tied.

A few new sections were added to the chapter on “other changes”, including the restrictions on third-party image capture support and dynamic Intent filters.

And, of course, there were lots of bug fixes.

I expect two more updates after this:

  1. Version 0.9 after Android 11-native hardware ships and I get my grubby little paws on a device

  2. Version 1.0 a month after Version 0.9, just for bug fixes
