Dialog click not working on Pixel 3 (Android 10)

[lsuski]

Description

On Pixel 3 (this is probably android 10 specific issue but I've tested it only on Pixel 3) simple clicking on dialog button immediately after it is shown does not work

Steps to Reproduce

1. Animations are enabled on device.

2. Run ExampleInstrumentedTest

Expected Results

ExampleInstrumentedTest should pass

Actual Results

ExampleInstrumentedTest fails on Pixel 3 and passes on older devices

AndroidX Test and Android OS Versions

espresso-core:3.2.0
androidx.test.ext:junit:1.1.1
androidx.appcompat:appcompat:1.0.2

Android 10 - api 29

We are seeing this as well.

The first click on the dialog just doesn't seem to register.

If you put a Thread.Sleep() (hack) just after the dialog is displayed (right before the click), it will work. If you change the click to a doubleClick(), it will also work.

If we run our tests individually, they pass. But if we run the entire class with multiple tests, that is when they become flaky.

I have created a sample project here https://github.com/asavill/esspresso_alert_dialog_issue with an espresso test class which fails 100% of the time when running on Android 10 and passes 100% of the time when running < Android 10.

Thank you to @lsuski for providing the other sample application.

Steps to Reproduce

Run ExampleInstrumentedTest

Expected Results

ExampleInstrumentedTest should pass

Actual Results

ExampleInstrumentedTest fails on API 29 and passes on older API versions.

Can you reproduce the issue with animations disabled? Its strongly recommended to disable animations when using espresso.

Hello, yes animations on or off does not make a difference.

Thanks we'll take a look

Loved the way you closed the issue without waiting for a response. And then haven't updated anything for like 4 months now?

This is android 10 issue. It happens in couple of devices with 10 we have for testing. Even after updating Nokia7.2 to android 10 this bug starts to show up.

Will this be fixed ? I'm also encountering this issue.

I confirm this happens on Samsung S10.

For what it's worth, I can confirm this happens on the SDK 29 emulator (with about a 50% failure rate for me) but not on the SDK 24 emulator.
androidx.test 1.3.0 (Espresso 3.3.0)

Also encountering this. Have not managed to find a robust solution other than adding a Thread.sleep. Waiting on visibility, clickablility etc doesn't help and putting in "try again on failure" style logic can cause problems. It feels like using a custom on click listener for dialogs that Espresso can inspect might be a workaround for whatever the real problem is but that'll be pretty invasive.
