This multi-apk application requires a device with API level 21+

Question

I want to automate the android test using CI(Jenkins), but I'm getting the following error once I executed the gradle connectedCheck:

:app:connectedAndroidTest

This is working fine in the workstation which has the Android Studio installed. But the server does not have Android Studio Installed, only Gradle and Android SDK (Tools and everything else).

My question is what am I missing to get the tests running using gradle connectedCheck on the server? Using the console in the work station they are working fine.

The work station is using Android Plugin Version 1.1.0rc-3 Gradle 2.3(same as the server) and the android sdks installed on both are the same.
