The "CheckDuplicateJavaLibraries" task failed unexpectedly. Error when building SampleBrowser

Hi,
I trying to build the SampleBrowser-Forms in the latest release of Essential Studio for Xamarin however when I do so, I get the following error :-
Error The "CheckDuplicateJavaLibraries" task failed unexpectedly.

I have tried to see if I can resolve this by installing some things from SDK Manager but the problem still persists.
How do I resolve this issue?
Kind regards,
Paul Diston

Hi Paul Diston 
 
Thanks for contacting Syncfusion support. 
 
This issue occurs due to the unavailability of Android Support Library. 
To fix this issue, 
Go to Android SDK Manager -> Packages -> Show Obsolete Packages -> Extras –> Android Support Library. Kindly check this package and install it. 
Please check and let us know if you need further clarifications. 
 
Thanks, 
Yuvaraj
