Beacon Control App issue #3
Description
Hi,
I have installed the beacon control sample app and tried to trigger the url actions via application page by assigning a zone with beacon devices, when i open the beacon control app it crashes and shows error as unfortunately app has been stopped.
Kindly suggest me a solution for this.
My Log shows as
