Unable to compile apk, Itext and Proguard conflict

I am developing an Android application, now I need to build an APK, for that I follow this step:

1) Build -> Clean

2) Build -> Generated Signed APK

3) Signature Jar or Full Signature APK

But when generating the application, an error occurs:

I don't know how to fix this problem.

What have I tried?

I put this code in my proguard-android file (located at \ AppData \ Local \ Android \ sdk \ tools \ proguard).

Rif

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

This solution does not work for me, the problem remains the same

**** CURRENT SOLUTION ****

Actually the only solution I found is set to this value in gradle:

1) shrinkResources false

2) minifyEnabled false

Try to put this in proguard rules



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

Try to put this in gradle:



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

If you keep all the classes iText

, what is the use of Proguard ?
If you look closely, you can see that all warnings contain a package com.itextpdf.text.pdf

, so we just keep that. And also org.joda.convert

. So we have:

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