I am developing an android app using Xamarin.Android.

Estimote beacons are not detected by the SDK and throw an exception as "09-04 11:08:58.512 E/EstimoteSDK( 7625): AbstractParser.parse:33 Unable to parse scan record: You need to initialize SDK first. EstimoteSDK.initialize(applicationContext, appId, appToken)". Kindly provide a solution to resolve this issue.

Expected behavior: Need to detect the beacons

Actual behavior: throws an exception
