android - 无法将 Amazon DynamoDB 导入 android？

Question

所以我正在尝试设置一个 Amazon 数据库，并且我正在按照此处的设置教程进行操作:http://docs.aws.amazon.com/mobile/sdkforandroid/developerguide/getting-started-store-query-app-data.html

但是导入都不起作用!当我导入以下内容时:

    import com.amazonaws.services.dynamodbv2.*;
    import com.amazonaws.mobileconnectors.dynamodbv2.dynamodbmapper.*;
    import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBAttribute;
    import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBHashKey;
    import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBMapper;
    import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBScanExpression;
    import com.amazonaws.services.dynamodbv2.datamodeling.DynamoDBTable;
    import com.amazonaws.services.dynamodbv2.datamodeling.PaginatedScanList;

这是我的依赖:

    compile 'com.amazonaws:aws-android-sdk-core:2.3.3'
    compile 'com.amazonaws:aws-android-sdk-cognito:2.3.3'
    compile 'com.amazonaws:aws-android-sdk-s3:2.3.3'
    compile('com.amazonaws:aws-android-sdk-mobileanalytics:2.3.3')
    compile('com.amazonaws:aws-android-sdk-apigateway-core:2.3.3')
    compile 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.3.3'

Answer 1

因为 dynamoDB 位于 com.amazonaws:aws-android-sdk-ddb:2.2.+。如果要使用dynamoDB mapper类使用POJO，需要导入
com.amazonaws:aws-android-sdk-ddb-mapper:2.2.+。

所以用这个代替

 compile 'com.amazonaws:aws-android-sdk-core:2.2.+'
 compile 'com.amazonaws:aws-android-sdk-cognito:2.2.+'
 compile 'com.amazonaws:aws-android-sdk-cognitoidentityprovider:2.2.+'
 compile 'com.amazonaws:aws-android-sdk-ddb:2.2.+'
 compile 'com.amazonaws:aws-android-sdk-ddb-mapper:2.2.+'
