NoClassDefFoundError：javax.xml.bind.DatatypeConverter

Question

我在Android应用程序中使用Amazon的Java SDK与SimpleDB进行通信。 我将sdk添加到gradle文件中，它一直运行，直到调用DatatypeConverter.printBase64Binary并且我收到以下错误：

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，或者至少在aws构建中包含javax库？

这是我的gradle文件，以防这有助于：

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()
}

遗憾的是，包javax.xml.bind。*在android上不可用，所以你不能使用amazon java sdk。

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