Android .Net 4.* dynamic link plugin callback error with native text share.

[sakiraykurt]

Unity 2018.2.18f1

It works with .net 3.* plugin but not with .net 4.*.

Scenario

1. I get a short link from the Firebase to Unity.
2. I send the received link to my share module.
3. Crash happens.

Idea
I think dynamic link thread is not dispatched to main thread after receiving a short link.

Configs

• plugin v5.4.3

• .net 4.* = mono

• Stripping level = disabled

Yeah it looks like you're calling into code that can't be called from a thread other than the main thread.

.NET 3.x and 4.x task libraries work differently. In the Firebase SDK we moved all task callbacks to the main thread in .NET 3.x but do not in .NET 4.x as we don't control the Task library. Anthony posted a workaround here:
#261 (comment)

We're also discussing whether to expose this functionality in the Firebase Unity SDK as a simple API that would allow you to post operations to the main thread using the same functionality we use inside the SDK.

Ok. Thanks. 👍
