@ptxmac Thanks for the contribution! I looked at this a bit and I think it's too risky to merge. Basically the situation is this. One of the main reasons to override the app identifier for logging is to enable analysis of a how an app is performing in different regions/countries. A single application can be tied in this way to multiple Facebook App IDs. App IDs and Client Tokens are a strict 1:1 relationship. Making a call with a mismatched App ID / Client Token pair will result in an exception. The risk this change presents is that a developer may not be aware of this relationship. They'll override the App ID for logging at runtime and not realize that they also needed to change the Client Token. This would be really bad. I think a better (though more involved) change would be to make it impossible for this bug to exist by disallowing setting the logging override in isolation. This would involve deprecating |

Happy to review any future contributions!!! Feedback is very welcome. :D |

Made some changes that handled the disastrous edge case so seemed safe to merge with those. Still happy to review any followup work that actually solves the structural issue outlined above. :D |
