Android Studio: Unable to obtain result of 'adb version'

Question

I am trying to start development on an Android app using Android Studio, but whenever I try to run the app I get the error Unable to obtain result of \'adb version\'

Answer 1

Found the solution thanks to @user3109468, Android Studio had the directory for the Android SDK wrong. In File>Project Structure make sure the directory for the SDK is correct; mine was C:\Users\[user]\AppData\Local\Android\sdk (Google had given sdk a capital "S" for some reason...)
