ClassNotFoundException: twitter4j.conf.PropertyConfiguration

Question

如果我不在我的项目上运行pro-guard，一切都很好，但如果我运行pro-guard并在设备中安装.apk，我就会得到以上错误。我尝试在proguard-android.txt文件

中添加以下行

-keep public class twitter4j.conf.PropertyConfigurationFactory
-dontwarn twitter4j.**

但没有任何影响。

我使用默认的proguard-android.txt文件从SDK

并将其设置在project.properties中，如下图

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

我看了看这个链接的相同问题，但不能理解，也谷歌没有帮助我太多。

那么，谁能告诉我这里出了什么问题?

Thanks in advance

这个类不是公共的，所以你应该删除-keep选项中的"public"关键字，否则模板将无法匹配。
