Solution 1

Go to Advanced System Settings, then go to Environment Variables and select PATH variable to edit. There you have to append path to platform tools and tools of sdk, for example like this
;C:\Development\android-sdk\platform-tools;C:\Development\android-sdk\tools

Now go to cmd and run android, if that does not open android sdk manager, then it means path has not been set correctly or cmd is not recognizing enviroment variable updtes, in that case restart your computer and it will work.

Solution 2

Go to Advanced System Settings, then go to Environment Variables Then add new Variables with name "ANDROID_HOME" and the value will be you SDK path like

C:\Android\sdk

Make sure to restart visual studio before run again

it will fix
