UI Tests fail to run with when using play-services-cast:21.3.0 #1831

Description

My Android app depends on protobuf-java:3.17.2, and uses espresso:3.5.1 for UI testing. espresso-contrib:3.5.1 depends on com.google.android.apps.common.testing.accessibility.framework:accessibility-test-framework:3.1.2 depends on com.google.protobuf:protobuf-lite:3.0.1

When I try to run my UI tests, my app immediate crashes with:

If I remove this dependency with gradle, things seem to work fine:

configurations.all {
    resolutionStrategy.dependencySubstitution {
        substitute module("com.google.protobuf:protobuf-lite") \
            using module("com.google.protobuf:protobuf-java:3.21.12") \
            because "Only espresso-contrib (via accessibility-test-framework) needs protobuf-lite, but everything else needs protobuf-java"
    }
}

Steps to Reproduce

Create a project that uses play-services-cast:21.3.0 and protobuf-java:3.21.12. Then try to run a UI test with espresso-contrib:3.5.1

Expected Results

UI Tests run

Actual Results

App immediately crashes with the above stack trace

AndroidX Test and Android OS Versions

Android API 33. Espresso 3.5.1

I filed a similar issue with the cast team: https://issuetracker.google.com/issues/285919735

I think the root cause here is that com.google.android.apps.common.testing.accessibility.framework:accessibility-test-framework should not depend on protobuf-lite because protobuf-lite doesn't guarantee binary compatibility across releases, so any app that uses a different protobuf-lite version (or protobuf-java) might have problems because of this dependency.
