Android “ProGuard构建失败”；“未解决的引用”；

我一直在开发我的应用程序的最新版本，它测试得很好，但当我进行版本ProGuard构建时，我会遇到很多错误，主要是因为找不到

org.apache.http.*

，我在项目中没有使用这些错误。我已经在整个项目中搜索了该文本，但找不到它。我添加了一些依赖项，但我认为没有一个依赖项会使用HTTP

我如何找出ProGuard抱怨的原因并正确处理？它说我可以“使用--stacktrace选项”运行，但我不知道怎么做

我感谢任何帮助，因为我发现ProGuard经常让人困惑

在将buildTool更新到23.0之前，我从未遇到过这个问题。我在我的应用程序中看到的最新版本的构建工具的唯一解决方法是，您需要将其添加到Progaurd.txt文件中

-dontwarn android.support.v4.**
-keep public class com.google.android.gms.* { public *; }
-dontwarn com.google.android.gms.**

如果在项目中使用Apache的Http，还需要包括以下行：

-keepnames class org.apache.** {*;}
-keep public class org.apache.** {*;}    
-dontwarn org.apache.commons.logging.LogFactory
-dontwarn org.apache.http.annotation.ThreadSafe
-dontwarn org.apache.http.annotation.Immutable
-dontwarn org.apache.http.annotation.NotThreadSafe

---

让我知道这是否也有助于解决您的问题。

如果您的应用程序使用旧的apache HttpClient，则必须将以下内容添加到build.gradle文件中：

useLibrary'org.apache.http.legacy'

---

正如这里所解释的：

请查看可能的重复情况。这是一个非常简单的问题，需要解决。在这里看到我的答案：我在23.0升级后遇到了同样的问题，并且-dontwarn com.google.android.gms.*修复了它。我不需要其他人。感谢you@Shine实际上，只有当您仍然使用旧的ApacheHTTP库进行网络调用时，才需要添加这些其他行。我在答覆中已作进一步澄清。谢谢你指出。你为什么需要com.google.android.gms的

public

？我仍然对

警告：twitter4j.TwitterAPIMonitor

和

警告：com.squareup.picasso

有问题。我怎么解决呢？我已经把

org.apache.http.legacy

放在我的

build.gradle

中了，但是我仍然有错误

-keepnames class org.apache.** {*;}
-keep public class org.apache.** {*;}    
-dontwarn org.apache.commons.logging.LogFactory
-dontwarn org.apache.http.annotation.ThreadSafe
-dontwarn org.apache.http.annotation.Immutable
