I get an error after creating amazon coginto in android

Question

Hi, I am doing a project that syncs data with amazon coginto and works fine, and also successfully signed apk.

Now the problem is that I get an error after debugging

"Unrecognized suffix for AWS b client class name"

Answer 1

You will probably enable Proguard and assign the class name obfuscated. The SDK does reflection based on the class name. Without it, some functions may not work correctly. For configuration see Instruction https://github.com/aws/aws-sdk-android/blob/master/Proguard.md .
