DatePicker causes Exception raised during rendering in LayoutEditor

Question

I have various layouts that use DatePicker, suddenly the layout editor stop to work showing a rendering error. If I Turn off the custom view rendering sandbox, the layout is rendered correctly; however is unclear the cause of this issue since I haven't changed anything, and before the error I needn’t have turn off rendering sandbox.

The full error stack:

Exception raised
during rendering
:
Write access
not allowed

This is a bug were Android Studio for some unknown reason isn't loading the temp files needed to draw the layout in "java.io.tmpdir", the issue is listed here: Android Issue:63279 The suggested fix is to update your SDK to the newest edition (if it's not already) and to also apply the latest Android Studio patch via "Help > Check For Updates".

Edit:

I found this to be helpful: Adroid Pickers UI Reference, after implementing the Date Picker as described here the error went away...
