I can't install Android SDK Tools on Android Studio (version 2.3).
I got the following error,
Is there anyway I can solve this error?
Google, for whatever reason, has decided to remove direct access to SDK Manager starting with Android STudio v2.3. If you run SDK manager directly using @iK2H 's instructions, you will see that SDK manager does not detect Android SDK Tools v25.3.1. It could be that v25.3.1 is only available via Android Studio settings, but this is broken for now.
