This is a helper application for use with MacroDroid. In most cases you will not need this, so please only install if prompted to from within MacroDroid.

For anyone interested in the technical details of why this file is required please read below.
When releasing for a Target SDK of 23 (Marshmallow), updating system settings requires a new special type of permission to be enabled (which MacroDroid prompts for). However, a few settings are now no longer able to be set, such as enabling/disabling the notification LED (see https://code.google.com/p/android/issues/detail?id=189701&can=1&q=notification_light_pulse&colspec=ID%20Status%20Priority%20Owner%20Summary%20Stars%20Reporter%20Opened)
To workaround this limitation, this very simple helper file is built against an earlier target SDK and the old requests are relayed to this helper file. In this way the old functionality will still work on Marshmallow devices (and beyond).
