This is caused by events either being dropped or received out of order.
Can you narrow this behavior down to any particular device and/or SDK version?

commit 809b6acbcbef583825e6f80af0e877fa946b9233
Author: Steve McKay <smckay@google.com>
Date: Fri Apr 05 10:47:13 2019

Cleanup Gesture selection.

Update GestureSelectionHelper:
- Remove some dead code that was attempting to set range anchor...but never called.
- Consult SelectionPredicate before trying to make a selection.
- Guard against handling events when SelectionTracker doesn't have an
active range.

Cleanup TouchInputHandler:
- Simplify logic for initiating gesture selection
- Don't try to initiate selection unless range is active.

BUG: 70518185
BUG: 109808552
BUG: 128054552

Test: Passing. Added new coverage in TouchInputHandler.

You can reproduce a crash like this by pressing Back to cancel selection while you're drag-selecting.

You can even do this in the Files app in Pie/Q.

Marked as fixed, reassigned to sm...@google.com.

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().

PS: this issue is a duplicate:
