I am building my Android app release build by enabling minifyEnabled and shrinkResources. I am using a library named spongycastle for cryptographic purposes. The problem I am facing is that the entire spongycastle code is being bundled with the apk even if I am using a small part of it. I am not sure which internal library has mentioned the keep rules for it. I tried looking for seeds.txt and usage.txt in my build output but only found mappings.txt and resources.txt files. Can someone point out what might be the reason for this?
Also, is there any other better way to debug this?
Check if the proguard.txt of the spongycastle library contains '-dontshrink'
