Question

尝试使用任何Drive类功能时：

Drive service = new Drive.Builder(AndroidHttp.newCompatibleTransport(),new GsonFactory(), credential).build();

我在libs文件夹中包含了正确的jar：

谷歌-API服务驱动-V2-rev123-1.18.0-rc.jar

并且进口很好：

导入com.google.api.services.drive.Drive;进口 com.google.api.services.drive.DriveScopes;

但它继续显示错误：

我相信您没有包含google-api-client-1.18.0-rc.jar库，这就是您获得例外的原因。

下载并解压缩Drive API library后，请阅读drive/readme.html。它列出了需要包含的google-api-services-drive-v2-rev123-1.18.0-rc.jar的依赖jar。从属jar可以位于drive/libs文件夹中。

以下是Android应用程序需要包含的完整jar文件集：

谷歌-API服务驱动-V2-rev123-1.18.0-rc.jar
谷歌-API的客户端 - 1.18.0-rc.jar
谷歌OAuth的客户端 - 1.18.0-rc.jar
谷歌-HTTP-客户1.18.0-rc.jar
jsr305-1.3.9.jar
谷歌-HTTP-客户GSON-1.18.0-rc.jar
谷歌-API的客户端 - 机器人-1.18.0-rc.jar
谷歌-HTTP-客户机器人-1.18.0-rc.jar

java.lang.NoClassDefFoundError：com.google.api.services.drive.Drive
