Я использую зависимость jackson-json в проекте Android и создаю Signed Apk в режиме выпуска, я получаю следующие ошибки: :

Answer 1

на основе this answer и this answer, вы можете игнорировать те предупреждения в файле Proguard с помощью:

-keepnames class com.fasterxml.jackson.databind.** { *; } 
-dontwarn com.fasterxml.jackson.databind.** 

Edit: Чтобы исправить новую ошибку времени выполнения в комментарии Белу w, add:

-keepattributes InnerClasses
