Move to SD Card Option Greyed out even for Compatible Apps I am using a Motorola Moto E with Android Kitkat and I am unable to move applications to my SD Card even for Apps that support moving to SD Card. 

I am using ART Runtime (Developer) instead of Dalvik.
When using ART, you cannot move apps to the SD card. 
Media moves are fine. 
You can switch to Dalvik, move apps, and then switch back to ART. 
ART is a developer option for Android Kitkat.
