Please provide the path to the Android SDK

HI, I'm started to use Android Studio but when I executed Android it sent me the alert:
Please provide the path to the Android SDK.

So I had been to analize the problem, I found the next:

• The Android Studio's path is c:\Archivos de programa\Android\Android Studio
• #Location of the SDK. This is only used by Gradle.

# For customization when using a Version Control System, please read the
# header note.
sdk.dir=C\:\\Android

But the Android path is C:\Program Files\Android\Android Studio, it's Ilogic becuase the Android sdk is C\:\\Android

Please help me.
