Do you happen to have any steps for this?
It was one time while running project - now it’s running.
:(. Not sure this will be actionable then, without more info, sorry.
I’ve got something similar, Water version is 10.0.0.2445, to reproduce open
\Elements\Samples\Oxygene\All\Calculator\Calculator.Android\Calculator.Android.elements from GitHub, and then press settings.

Reproduced and fixed; it only happens when no Android SDKs are found.
this isn’t the same error as originally reported by this thread tough.
