use of undeclared identifier 'akBottom'

I use FMX to create Android application. I create component in runtime and have problem with anchors.
headers #include <System.UITypes.hpp> and #include <FMX.Controls.hpp> placed but this code :
CheckBox->Anchors <<= akBottom; receive error "use of undeclared identifier 'akBottom'"
this version : CheckBox->Anchors = TAnchors() << akTop << akRight; not work too
What to do ?
