Write a log.txt file to save log

Unity Engine
1

Hi,
I am working on some apps develop program, and I sometimes get error report from specific cellphone(maybe this time is samsung and next time might be Htc). That really annoyed me a lot.
So I was wondering if it’s possible for me to write a log.txt file in sdCard(on phones) or Desktop(pc).
I’ve done some research about this topic, but it seems not work for me.
I read this File I/O in Unity3D - PreviewLabs
and also http://www.thegameengineer.com/blog/2014/02/09/unity-11-logging/.

But I got error like “access to /…/ path is denied”. I think it’s permission issue, and have no idea how to fix that. Is there anyone can give me a hand with this? Thanks in advance.

If its for Android you need to add the permissions to the manifest. Also are you using Application.persistantDataPath?

If you want the files to be written to the SDcard you need to go to the:
1.) player settings
2.) Android (icon should already be set since the target build is Android)
3.) Under “Other Settings” → Write Access
Set it from “Internal” to “External (SDCard)”

For android it is recommended to use Application.persistantDataPath not Application.dataPath just in case.
