If you are facing this on Android Studio, follow along

1) Uninstall Android 4.4W(API 20) from the SDK Manager

2) Make sure you have Android SDK Build Tools 19.1 installed from the SDK Manager.

3) Edit build.gradle within your app folder. Set the following two values as below

compileSdkVersion 19
buildToolsVersion "19.1"

4) The IDE will prompt you to sync the Gradle file with your project, click Yes.

5) Open your activity file and then change the 'Android version to use when rendering layouts in IDE' to 'API 19'. This is the green colored Android Bot towards the right on the preview window
