【问题描述】：

编辑：我的 PROGUARD 版本是 4.7

今天我尝试在我的android应用程序中包含jsoup (version 1.7.1)，但这给我带来了很多麻烦。当我导出签名的apk 和proguard 打开 每次我的应用程序面临强制关闭问题时，我禁用了proguard 并导出了apk，它运行完美。请帮我。我该如何解决这个错误？堆栈跟踪如下：

【参考方案1】：

@Erdem 在上面的评论中发布的解决方案似乎是最好的解决方案。我将其转发为可见性的答案。

将下面的行添加到您的 proguard 文件中

-keeppackagenames org.jsoup.nodes

这似乎足够了

【讨论】：

谢谢 - @android-newbie 应该会接受它;-)

【参考方案2】：

你可以去jsoup with proguard寻找答案，也就是在proguard-project.txt中添加以下内容：

-keep public class org.jsoup.** 
public *;

【讨论】：

无需保留所有内容。这就足够了：-keeppackagenames org.jsoup.nodes

救生员...:)

【参考方案3】：

只需在 proguard-rules.txt 中添加这些行

#Jsoup
-keep public class org.jsoup.** 
public *;

-keeppackagenames org.jsoup.nodes
