Threaded Conversation: No Unread Button when new message partly visible

If a message is received in a private group while the group is open, the message doesn't appear until the screen is rotated.

This may be device-dependent: it happens on the Moto G 4G and the Moto E3, but not on the Galaxy Nexus.

I did not notice this in our testing and we were using private groups, probably device dependent (EmojiTextView ?)

changed milestone to %Android Beta 1

I've just been able to reproduce a similar issue on the Galaxy Nexus and Moto G 4G: if a group message arrives while the group is open but the screen is locked, unlocking the screen shows the group without the new message. Both devices were showing notifications for the new message on the lock screen, so they'd received it.

The screen can be locked and unlocked again without the new message appearing. However, rotating the screen causes the new message to be shown. If the new message hasn't been forced to appear by rotating the screen and a second message arrives, neither message appears until the screen is rotated.

If the new message hasn't been forced to appear and I exit the group, the unread message counter shows the unread message. Re-entering the group causes the message to appear - it's below the viewport so the quick scroll button is shown.

Same issue exists with forums.

The second problem (messages not appearing until screen is rotated) is in code review.

The first problem may have been caused by the new message having just a few pixels visible at the bottom of the screen - this would mean the quick scroll button wouldn't appear because the message would technically be visible, so there would be no noticeable indication that a new message had been added.

Need to re-test this, sounds like it's fixed.

changed the description

The second problem (messages not appearing until screen is rotated) is in code review.

So this one got fixed.

The first problem may have been caused by the new message having just a few pixels visible at the bottom of the screen - this would mean the quick scroll button wouldn't appear because the message would technically be visible, so there would be no noticeable indication that a new message had been added.

I could reproduce this one by filling the conversation in a way that only a little bit of space is left at the bottom. Maybe when moving to new visibility detection (via the LayoutManager), we can take this into account?
