Question

我开发了包含Dropbox，Google驱动器和Box云服务的Android应用程序。我测试了它，一切正常。之后我签了它，我意识到调试apk大小是8.5MB而签名的apk大小是7MB。我测试了完整的应用程序，其中一切正常，除了Box云功能。我得到以下异常

它没有获得它在debug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。提前谢谢。

Answer 1

由于jackson库在使用proguard进行编译时我得到了这个问题，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.** { 
    *; 
}

java.lang.NoSuchFieldError：PUBLIC_ONLY在使用已签名版本的android中的Box api时
