NoClassDefFoundError: javax.xml.bind.DatatypeConverter

Question

我在我的 Android 应用程序中使用亚马逊的 Java SDK 与 SimpleDB 进行通信。我将 sdk 添加到 gradle 文件，它一直运行到调用 DatatypeConverter.printBase64Binary 并且出现以下错误：

java.lang.NoClassDefFoundError: javax.xml.bind.DatatypeConverter
        at com.amazonaws.util.Base64.encodeAsString(Base64.java:36)
        at com.amazonaws.auth.AbstractAWSSigner.signAndBase64Encode(AbstractAWSSigner.java:69)

不应该自动包含 javax 库，或者至少包含在 aws 构建中？

这是我的 gradle 文件以备不时之需：

buildscript {
repositories {
    mavenCentral()
    maven { url 'https://maven.fabric.io/public' }
}
dependencies {
    classpath 'com.android.tools.build:gradle:1.1.2'
    classpath 'io.fabric.tools:gradle:1.+'
}
}
apply plugin: 'com.android.application'
apply plugin: 'io.fabric'

repositories {
mavenCentral()
maven { url 'https://maven.fabric.io/public' }
jcenter()
}

不幸的是 javax.xml.bind.* 包在 android 上不可用，因此您不能使用亚马逊 java sdk.

但对于 android，您可以使用 aws 移动 SDK，请访问 http://aws.amazon.com/mobile/sdk/
