当我调试我的应用程序时，它工作正常，但当我尝试导出我的apk并安装它时，我会遇到以下问题：

我在用Proguard，
我还添加了如下引用lib：
-libraryjars /libs/org.apache.httpcomponents.httpclient_4.2.1.jar
-libraryjars /libs/signpost-commonshttp4-1.2.1.1.jar
-libraryjars /libs/signpost-core-1.2.1.1.jar
-libraryjars /libs/signpost-jetty6-1.2.1.1.jar
-libraryjars /libs/twitter4j-core-2.1.6.jar
你知道吗……@谢谢
最佳答案
你的libs中没有httpcore。
请导入HttpCore
这个链接是httpcore 4.1，你可以搜索httpcore4.2或4.3。
以后导入库时，请确保导入相关库
