Android Studio中Dex合并失败问题求助

Hey there! I totally get how frustrating it is to hit repeated errors when trying to store data in AWS DynamoDB—let’s break this down step by step to get your app working.

First off, you mentioned sharing your Gradle file, but it looks like the actual content didn’t come through. To diagnose the issue thoroughly, could you share a few more key details:

• Full error message/stack trace: The exact error text (like access denied exceptions, SDK mismatches, or connection errors) is critical—this tells us where the failure is happening.
• DynamoDB code snippets: Share the parts of your code where you initialize the DynamoDB client and perform the write operation. This helps spot issues with client configuration, table name mismatches, or incorrect item formatting.
• AWS credential setup: How is your app authenticating with AWS? Are you using environment variables, an IAM role (if running on EC2/EKS), or a local credentials file? Also, double-check that the associated IAM entity has dynamodb:PutItem (and any other required) permissions for your target table.
• Relevant Gradle dependencies: Paste the section of your build.gradle file that includes AWS SDK/DynamoDB-related dependencies. Version mismatches or missing dependencies are a common culprit here.

For example, a common pitfall is mixing AWS SDK v1 and v2 dependencies, which can cause conflicting classes. If you’re using SDK v2, your dependencies should look something like this:

implementation platform('software.amazon.awssdk:bom:2.20.0')
implementation 'software.amazon.awssdk:dynamodb'

Once you share these details, we can pinpoint exactly what’s going wrong and fix it quickly!
