Azure Pipeline: No such file or directory

[guilhermegals]

Docker image: Ubuntu 18.04
Language: Kotlin
UI Test framework: Espresso

Hello!

I read the Medium article "Android UI Testing in Azure DevOps" to able my pipeline to run my Android UI Tests. But i'm having some troubles trying to start the emulator on pipeline. For some reason when i run the command with "$ANDROID_SDK_ROOT/emulator/emulator" or "$ANDROID_SDK_ROOT/platform-tools/adb " is returned "No such file or directory"

I put some logs in pipeline and as we can see on print, the folders "emulator" and "adb" exists and have the executable

The image was downloaded and cached successfully

Can you help me?

Here is my azure-pipeline file:

When using a path that uses an environment variable, the first thing to check is that the environment variable actually exists. My local system doesn't have $ANDROID_SDK_ROOT. I use $ANDROID_HOME both locally and in my pipelines.

You can see that I use $ANDROID_HOME in my variables section and in my emulator-related steps.

If you want to see all your environment variables, you can do a PowerShell one-liner step in your yaml:

- pwsh: Get-ChildItem env:

(trailing colon is not a typo, try out Get-ChildItem env: on your own machine.)
