ClassNotFoundException：twitter4j.conf.PropertyConfigurationFactory：Android
如果我没有在我的项目上运行pro-guard，一切都很好但是如果我运行pro-guard并在设备中安装.apk，我就会遇到错误。 我尝试在proguard-android.txt文件中添加以下行
-keep public class twitter4j.conf.PropertyConfigurationFactory -dontwarn twitter4j.**
但它没有任何区别。
我正在使用SDK默认proguard-android.txt文件
并在project.properties设置它，如下所示
proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
我看了这个链接同样的问题，但无法理解，谷歌搜索并没有帮助我。
那么，有人可以告诉我这里有什么问题吗？
提前致谢
