I have just found that this exception will be thrown when I called the method

UploadValues(String, String, NameValueCollection) of System.Net.WebClient

So I use UnityEngine.WWW instead without exception.
Anyway this case still does not make sense to me. It will be great if you could explain to me. Thank you.

Hi patipol

I want to make sure I understand what you're saying. Are you trying to use 'UploadValues(...)' when calling one of the tracking methods (if so, could you include a snippet of what the call looks like)? Or are you using UploadValues(...) somewhere else in your code and the plugin is conflicting with it? That will help me narrow down the problem.

Thanks!

I am using UploadValues(...) somewhere else in my code and the plugin is conflicting with it. This occurs after imported googleanalyticsv3.unitypackage to the project.

I have got same error while I try to use System.Net call.

EXC_BAD_ACCESS to line 243 file GAIHandler.h
NSString *attris = [NSString stringWithUTF8String:parameters];

What is this send(const *char parameters) method used for?

I see no use of it in GoogleAnalyticiOSV3. But somehow it is called by System.Net

Currently it is not being used. I have removed it until I determine a solution for the conflict, so I will leave this issue open. Thanks to you both for your help and feedback!
