我开发了包含 Dropbox、Google drive 和 Box 云服务的 android 应用程序。我对其进行了测试，一切正常。之后我签署了它，我意识到调试 apk 大小为 8.5MB，而签名 apk 大小为 7MB。我仍然测试了完整的应用程序，其中除了 Box 云功能之外一切正常。我得到了以下异常

它没有得到它在调试中找到的库。我该怎么做才能解决这个问题？请帮我。由于这个问题，我无法发布我的应用程序。提前致谢。

我在使用 proguard 编译杰克逊库时遇到了这个问题，我通过在 proguard 文件中添加以下行来修复它。

-keepnames class com.fasterxml.jackson.** { 
*; 
}
-keepnames interface com.fasterxml.jackson.** { 
    *; 
}
