Look like an error from okhttp.
May I know which okhttp version are you using?

[N0lex]

@haoliu-amp Please download Amplitude SDK 1.1.0 and you can see the okhttp version.

[haoliu-amp]

Amplitude SDK depends on okhttp library. The old SDK is the one using a very old version of okhttp 3.10.0.

Since Amplitude Unity SDK 1.0.0, we updated the okhttp to be 4.2.2, since it fixed a lot vulnerabilities.

However, okhttp dropped the support for < 5.0 since 3.13.
Please read this. https://developer.squareup.com/blog/okhttp-3-13-requires-android-5/

But you can still use the new SDK with older version okhttp if you wanna get KitKat supported.

How to do it -

If you import library by copying the jar file, you can downgrade okhttp library by replacing it with a version < 3.13.
If you use google dependency resolver, update the dependency version for okhttp in *Dependency.xml file.
