This isn't fixed in alpha 6 :(. It's easily reproducible by starting a drag with one finger and then tapping somewhere else (think back button) which calls clearSelection().

Fix is in the works. Until then, a workaround is to avoid calling SelectionTracker#clearSelection while a gesture or mouse-band selection operation is in progress. Such a condition is likely not reflective of user intent (given the ongoing stream of selection operation), but reflective of a stray tap.

BTW, working on a fix for this (general improvement to state management). My unassigning this issue from me should not be construed as lack of attention to the matter. I just manage issues by hotlist (rather than ownership).

With latest support lib (25.0.0), the problem did not appear any more. Also with previous (24.2.1). Thanky you.

[StaggeredGridLayoutManager] Avoid OutOfBounds exception during mutations if SpanLookup data structure has not yet been lengthened
**Background**
A use case within our app ran into this issue frequently as a result of inserting items between a set of full span items. We applied numerous band-aids (clearing of the span cache, filler items, etc.), but those had a bunch of unintended side-effects.
- Within the code, my first approach was to limit the array fill to `MIN(length, position)`, but that really didn't feel like the right fix.
- Digging deeper, I found that the position being extended to with `ensureSize()` did not factor in the maximum extent of items in `mData` or `mFullSpanItems` (which do not necessarily have the same "cap" in terms of position / length).
- A fix that I tried relating to this was to always `ensureSize()` for mData's length, but that results in expontential growth because of the fact that mData's length ≠ number of items.
- To keep it simple, I realized the easiest thing to do is just ensure that mData is large enough for the `item count` we're supposed to be displaying.
- Through discussion in review, we ended up reverting to the simpler version using `MIN()`.
Note that the test case does something which I *think* is pretty uncommon in vanilla adapters, but is the case for us when using it paired with Litho. That was the easiest repro case for me to arrive at, but I'm sure there are others.

Test: New test case in StaggeredGridLayoutManagerTest validates that the `Arrays.fill()` invocation does not lead to a crash.

Description
I'm doing this the first time, so please have merci ;)
I am using a StaggeredGridLayoutManager in my RecyclerView inside of a Fragment.
While performing a search over a list the vizualisation works as it should and items are getting removed and added.
But after filtering all elements of the list out so the view is empty and then removing the additional letter so the previous items should be seeable again, an ArrayIndexOutOfBoundsException is thrown at java.util.Arrays.checkStartAndEnd(Arrays.java:1732) with the message "start < 0 || end > len. start=-1, end=11, len=11".
I added the output of "adb bugreport" and added also the main folder of my project, so you can hopefully understand what I am talking about and reporoduce the error.
The Exception is happening on all devices I could use to test, inclusive the emulator (I only had Devices with API lvl 22 & 23).
If you need any further informations I will provide them.
Also I hope that this is a real Bug and not caused by my own stupidity.
Yours sincerely,
David Artmann
