GoogleAnalytics-iOS-SDK crashes on deep links #652

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago 
Name of affected component: Core Reporting API

Name of related library and version: GoogleAnalytics-iOS-SDK

Issue summary:
If you open your iOS app with a deep link such as `myAppName://` Google 
analytics crashes every time.  This bug seems to have been introduced in 3.11, 
and is still in 3.12.  version 3.10 and lower are fine.

Steps to reproduce issue:
1.  Open your iOS app with deep link  `myAppName://` without any extra 
parameters
2.  GAIBatchingDispatcher crashes trying to perform a string method on an 
NSNull object

Expected output:
GAIBatchingDispatcher to not crash trying to perform a string method on an 
NSNull object

Actual results:
 GAIBatchingDispatcher crashes trying to perform a string method on an NSNull object

Notes:

Happens 100% of the time.  Floods of crash reports coming in since we updated 
Google Analytics SDK to above 3.10.
