When one download clean android-sdk archive and does not download anything above that (platform tools, platforms etc.) there is no possibility to start Android Manager from Netbeans. Steps: - download clean android sdk distribution, unpack - start netbeans - select proper sdk directory location in Options -> Miscellaneous -> Android and accept it - choose tools -> Android SDK Manager
Dialog pops up with information, that there is no Android SDK directory set.
When I download (through Android SDK Manager) platform and build tools the bug dissapears.
