AWS Amplify Crashes on Android 6

I'm trying to use AWS amplify on android 6, but the app crashes suddenly after 30 seconds after the Configuration and gets this error.

The basic problem here is that the app is trying to reference a class which doesn't exist at runtime:

java.lang.ClassNotFoundException: Didn't find class "java.time.LocalDateTime"

Initial runtime support for java.time.* was added to Android in API Level 26. For a period of time, java.time.* only worked on these devices.

As of Android Studio 4, java.time.* APIs can be "de-sugared" at build time. When using this functionality, the resulting code will run on all versions of Android. To benefit from this support, you must have Android Studio 4 or higher, and enable "core library desugaring." See the documentation for more details: https://developer.android.com/studio/write/java8-support#library-desugaring
