@gaaclarke - can you find someone to take a look at this one? All the tests are green, its hidden steps that are failing.

This looks like some crash related to the JNI layer:

@mboetger

@mboetger this flake appears to be a failure in the JNI layer when performing platform view tests. This sounds like something the android team would have a good handle on. Let us know if we can help.

[prod pool] flaky ratio for the past (up to) 100 commits between 2026-09-09 and 2026-09-15 is 0.00%. Flaky number: 0; total number: 98.

Closing as no longer flaky
