no tools folder in my android -> sdk
as I know it should be there but it isn't. Only things id sdk folder:
--- add-ons (folder) --- build-tools (folder) --- docs (folder) --- AVD Manager (app) --- SDK manager (app)
Found solution
Control panel (View by icons instead of Category (in the top right)) -> folder options -> view -> hidden files and folders:
check "Show hidden files, folders, and drivers "
Apply -> ok.
