Anrdoid, gradlew installDebug

Hi , I'm trying to just compile and run a sample project . I have imported the android demo project in my eclipse workplace and in Demos path I try to run "gradlew installDebug" in command prompt and I get this message : " SDK location not found. define location with sdk dir in the local properties file or with and Android_home environment variable"
I'll appreciate if you can help me with this.
thanks

It would be great if there was an eclipse template project or demos project which could be easily imported into eclipse.

Could you file a ticket for Eclipse template on https://github.com/Estimote/Android-SDK? We will accommodate that within future releases.

Regarding Gradle. You need to tell it where your Android SDK is located. That is in terminal define:
export ANDROID_HOME=/path/to/android/sdk
