The problem is incorrect version of DynamoDB mapper. 问题是DynamoDB映射器的版本不正确。 Please bump
com.amazonaws:aws-android-sdk-ddb-mapper
to 2.2.13 or later. 请将
com.amazonaws:aws-android-sdk-ddb-mapper
提升至2.2.13或更高版本。 The structure of AWS Android SDK libraries has been changed from 2.1.x to 2.2.x. AWS Android SDK库的结构已从2.1.x更改为2.2.x。 Please don't not mix them.
请不要将它们混合。
