无法编译apk，Itext和Proguard冲突

标签： java android itext

我正在开发Android应用程序，现在我必须构建一个APK，为此我按照这一步执行：

1）构建 - ＆gt;清洁

2）构建 - ＆gt;生成签名APK

3）Jar签名或完整APK签名

但是，当应用程序的生成发生错误时：

我不知道如何解决这个问题。

我尝试了什么？

我已将此代码放在我的proguard-android文件中（位于\ AppData \ Local \ Android \ sdk \ tools \ proguard中）。

Rif 

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

此解决方案对我不起作用，问题仍然存在

****当前解决方案****

实际上，我找到的唯一解决方案是在gradle中设置此值：

1）shrinkResources false

2）minifyEnabled false

3 个答案:

答案 0 :(得分：5)

尝试将其放入proguard-rules 

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

答案 1 :(得分：2)

尝试将其放入gradle中：

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

答案 2 :(得分：1)

如果您保留iText的所有课程，那么 Proguard 的用途是什么？ 如果仔细观察，您会发现所有警告都包含com.itextpdf.text.pdf包，所以我们保留这一点。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.**
