So you want to receive the Android L visual goodness of Material design, but don’t want to or can’t install the developer preview. If you’re rooted and running the Xposed framework then the Android L theme package may be for you.
Whilst it is only the visuals of the Android L version, and doesn’t include the functionality, it sure beats installing a buggy ported ROM or early developer preview.
The Android L module contains themed statusbars, calculator, settings app, boot animations, fonts, and ringtones.
Couple this with the Android L app package and you’re pretty close to that Android L experience. Hit up the source link to get started.
