Proguard won't work with iText library. the errors are related to org.spongycastle.** org.bouncycastle.* and com.itext.pdf.** I have tried to use keep on these packages without success.
My proguard config file is this:
-optimizations !code/simplification/arithmetic,!code/simplification/cast,!field/*,!class/merging/*
-optimizationpasses 5
-allowaccessmodification
-dontpreverify
-dontusemixedcaseclassnames

Error:ProGuard: [MyApp] You may need to add missing library jars or update their versions.
Error:ProGuard: [MyApp] If your code works fine without the missing classes, you can suppress
Error:ProGuard: [MyApp] the warnings with '-dontwarn' options.
try with these two lines:
-keep class org.spongycastle.** { *; }
-dontwarn org.spongycastle.**
Your logcat is already saying:
If your code works fine without the missing classes, you can suppress the warnings with '-dontwarn' options.
This works fine for itextg-5.5.10
# proguard configuration for iText
-keep class org.spongycastle.** { *; }
-dontwarn org.spongycastle.**
-keep class com.itextpdf.** { *; }
-keep class javax.xml.crypto.dsig.** { *; }
-dontwarn javax.xml.crypto.dsig.**
-keep class org.apache.jcp.xml.dsig.internal.dom.** { *; }
-dontwarn org.apache.jcp.xml.dsig.internal.dom.**
-keep class javax.xml.crypto.dom.** { *; }

-keep class org.apache.xml.security.utils.** { *; }
-dontwarn org.apache.xml.security.utils.**
-keep class javax.xml.crypto.XMLStructure
-dontwarn javax.xml.crypto.XMLStructure
I used Image to add in Table and I got error like NoSuchMethodFound:
I added following lines in proguard, its working fine now.
-keep class org.spongycastle.** { *; }
-dontwarn org.spongycastle.**
-keep class com.itextpdf.text.** { *; }
-dontwarn com.itextpdf.text.**
Thank you.
