Can you provide us a minimal example to reproduce this issue?

This looks similar to googleapis/google-cloud-java#5810, although that should have been fixed in 1.22.0 as that version depends on gax-java 1.50.1, and the bug was fixed in 1.49. Since you are using Android Studio I assume you are using Gradle, and Gradle would get those versions right.

This error generally is caused by a bug in something using gRPC. Any scheduledExecutors should be kept running until the ManagedChannel is terminated, not just shutdown.
