我正在开发一个Android应用程序,现在我必须构建一个APK,为此我按照这一步骤:

1)建立 - >清洁

2)构建 - >生成签名APK

我不知道如何解决这个问题.

我试过了什么？

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

里夫

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

这个解决方案对我不起作用,问题依然存在

****当前解决方案****

实际上我发现的唯一一个解决方案是在gradle中设置这个值:

1)shrinkResources false

2)minifyEnabled false

Answer 1

试着把它放在proguard规则中

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