Azure App Center- Android Xamarin test run error on Windows fix

There are quite a few steps to run apps on the App Center while configuring Test Runs in Xamarin.

First, install the following:

  1. Android SDK
  2. Visual Studio 2019 with the Xamarin addon in the Visual Studio Installer:
    1. visual studio xamarin install
  3. Java SDK

Once everything was installed, I restarted my command prompt, opened my Xamarin Android app project in VS and did a Debug build to demo the app. Once I did this, that triggered the build for the APK file.

Then I do the commands the over in the web browser Microsoft App Center (, but I add a bug fix parameter to the end of the Running Tests command (–uitest with path).

Microsoft Azure App Center appcenter test run uitest

appcenter login

appcenter test run uitest --app "DevOps-Training-1/Android-xamarin" --devices "DevOps-Training-1/both" --app-path C:\vs\MobileDevOps\MobileDevOps\bin\Debug\com.companyname.MobileDevOps.apk --test-series "master" --locale "en_US" --build-dir C:\vs\MobileDevOps\UIAndroidTest\bin\Debug --uitest-tools-dir C:\Users\EricSchrader\.nuget\packages\xamarin.uitest\3.0.3\tools

You will get an ANDOID_HOME error,

(No path) - Not set. [ Source: ANDROID_HOME ]

Then, set the ANDOID_HOME Windows Android SDK location (make sure you replace the user desktop account with your current user path)

set JAVA_HOME=C:\Users\EricSchrader\AppData\Local\Android\Sdk
set PATH=%PATH%;%ANDROID_HOME%\tools;%ANDROID_HOME%\platform-tools


That should get you to the next error, JAVA_HOME.

If you see this error:

Java Development Kit (JDK) not found. Please make sure that it is installed and if it's still not located, please set the JAVA_HOME environment variable to point to the directory.

Then, set the JAVA_HOME path (and make sure your JDK version matches)

set JAVA_HOME=C:\Program Files\Java\jdk-14.0.2

Once all is done, the app test will be submitted and complete without issues:
