Is this in an Activity or Service? – codeMagic Nov 29 '16 at 20:01 — codeMagic, Nov 29 '16 at 20:01

getSystemService is a method of Context.

Seeing as this can not be resolved, I can assume that you are not calling it from the context of an Activity, which extends Context itself.

Whichever object you are currently in, needs to be passed the context object from the calling activity.

This object can be retrieved using getApplicationContext().
