Adding Android SDK to Unity

Im having a weird problem adding the android sdk to my unity project. Under Edit > prefrences > external tools > Android SDK location it says browse. So I click on it and thats where Im stuck. Its not excepting any location at all. I clicked on the Android Folder, the studio folder. Every folder in there and nothing works. What am I doing wrong?? I see this everywhere online: C:\Program Files (x86)\Android\android-sdk but all i found was Android\Android Studio\ no sdk.

Please help, thank you

You havent installed the SDK.

Downloading Android Studio or eclipse or ADT or anything Android will give you a file called

SDKManager.exe

Use it. It you can’t find it …
