无法编译apk，Itext和Proguard冲突

javaandroiditext

5

我正在开发一个Android应用程序，现在我需要构建一个APK文件，为此我按照以下步骤进行：

1）Build -> Clean

2）Build -> Generate Signed APK

3）选择Jar Signature或Full APK Signature

但是，在生成应用程序时出现了错误：

我不知道如何解决这个问题。

我尝试了什么？

我在我的proguard-android文件中加入了这段代码（位于\AppData\Local\Android\sdk\tools\proguard）。

Rif

-keep class org.spongycastle.** { *; }
-dontwarn org.spongycastle.**

这个解决方案对我不起作用，问题仍然存在。

**** 当前的解决方案 ****

实际上，我找到的唯一一个解决方案是在gradle中设置以下值：

1) shrinkResources false

2) minifyEnabled false

- Mattia

如果你想使用Proguard来缩小你的应用程序，那么你的解决方案是不正确的，因为你正在禁用它。但是除此之外，它是正确的。 - Mahdi-Malv

禁用Proguard肯定不是解决方案... - Pablo Rodriguez

尝试将以下内容添加到Gradle中：

android{
...
 dexOptions {
    jumboMode true
}
...
}

实际上我找到的唯一解决方案是设置以下两个属性：1) shrinkResources false 2) minifyEnabled false。 - Mattia

如果您保留所有iText类，那么使用Proguard的意义何在？
仔细观察，您会发现所有警告都包含com.itextpdf.text.pdf包，因此我们只需保留它。还有org.joda.convert。所以我们有：

-keep class com.itextpdf.text.pdf.** {*;}
-dontwarn com.itextpdf.text.pdf.**
-keep class org.joda.convert.** {*;}
-dont warn org.joda.convert.**

尝试将此放入proguard规则中

-keep class com.itextpdf.** { *; }
-dontwarn com.itextpdf.**
