I got Unity Packages from: http://sdk-for-net.amazonwebservices.com/latest/aws-sdk-unity.zip

Its version: aws-sdk-unity_3.3.750.0

I've added AWSSDK.S3.3.3.111.4.unitypackage to my project, and added references to all its libraries in my assembly references.

Works fine in Unity Editor buy I am getting that error on Android device

Expected Behavior

App runs correctly

Current Behavior

Closing the issue - the problem is missing manifest. I've made another one for not working SDK on unity 2019+

[BatteryAcid]

For me this was a Unity build issue. I had to add a link.xml file to my Assets folder and list all the AWS SDK assemblies (Plugins) I'm using.
See https://docs.aws.amazon.com/sdk-for-net/v3/developer-guide/unity-special.html

hi @BatteryAcid
Im facing a issue.
When I remove "minsdk" line from manifest.
the apk builds fine but as soon as I openit it crashes.
And if I delete the manifest now build is working properly there is no crash, but the AWS SDK is not working.

let me know if this was the issue faced by you?
