I've included my own machine as DevOps Build Agent. This machine can build Android Apps without problems. But still it complains about demands not met:
java JDK AndroidSDK vstest Agent.Version -gtVersion 2.116.0
I installed the latest Java Development Kit 8, this should add java and JDK, but still it complains. Agent version is newer than 2.116, and latest Visual Studio is installed on the machine.
Could anyone guide me in the right direction here. I can't see anything missing on the machine, but still it's not valid for the Agent Pool to build Xamarin Android Apps.
