为什么要添加com.google.gdata:core:1.47.1？
如果你在它的官方网站上阅读：http://code.google.com/p/gdata-java-client/，上面写着：
Android支持：如果您正在为Android开发，并且您想要使用的Google API包含在Google Play Services库中，您应该使用该库以获得最佳性能和体验。如果你想与Android一起使用的Google API不是Google Play Services库，您可以使用Google API客户端Java库，支持Android 1.5(或更高版本)，并提供其他功能，如OAuth 2.0和Maven。
它建议您使用：
repositories {
mavenCentral()
}
dependencies {
compile 'com.google.api-client:google-api-client:1.18.0-rc'
}
对于谷歌播放服务非常重要，不要直接使用"整个"依赖：
dependencies {
compile 'com.google.android.gms:play-services:7.0.0'
}
