Exception raised during rendering:
java.lang.System.arraycopy([CI[CII)V

To resolve the issue I had to install SDK Platform Android L Preview via Android SDK Manger.

Android Studio SDK Manager

Then, change API level from API 20: Android 4.4W to API 20: Android L (Preview).

Android API level

Android Studio Beta 0.8.9
Windows 8.1
