I'm installing Android SDK for the first time on Windows 10. Facing problem with sdkmanager tool. Looked up several threads for solution, but to no avail.

C:\Users\vboppa>flutter doctor -v

When I tried to verify Android licenses, the following was the output.

C:\Users\vboppa>flutter doctor --android-licenses

Android sdkmanager tool not found (C:\Users\vboppa\AppData\Local\Android\sdk\tools\bin\sdkmanager).

Solution 1: chihau

You need to install Android Studio

A quote from Flutter documentation https://flutter.dev/docs/get-started/install/windows#android-setup

Flutter relies on a full installation of Android Studio to supply its Android platform dependencies
