I've installed Android Studio along with sdk , but in sdk manager notifies that sdk has been partially installed and also some of the options in sdk like (sdk tools and sdk updates sites tab are disabled). Also I'm not able to add previous or other sdk versions. Sdk Manager show the updates , but its disabled and thus not able to download and install them.
Yes I've tried to run as admin, but it didn't help.
The standalone SDK Manager can only be run via command line. In other words, the listing of contents prints on the command line - not in a GUI.
The Graphical User Interface for the standalone SDK Manager has been deprecated.
Yet, there is still a version that can be run on the command line. On Windows this can be from a Command (DOS) window.
The recommended way to manage the Android SDK is to use Android Studio Settings, rather than any standalone SDK Manager. This is a relatively new change. Good luck.
The built-in SDK manager is still not perfect. Use the standalone SDK manager.
