J'utilise ProGuard pour obfusquer mon apk, mais il n'y a aucun changement dans les noms de classe et de méthode - ils sont les mêmes qu'avant. Seuls les noms des variables sont modifiés.
La plupart d'entre eux n'étendent pas les classes comme Activity ; il y a un peu d'héritage dans mon code, mais il est écrit à 100% par moi-même.
J'utilise d2j-dex2jar et jd-gui pour vérifier les résultats.
Certaines classes sont exclues à cause de l'utilisation de GSON, voici mon proguard-project.txt :
-keep class com.google.ads.** # Don't proguard AdMob classes
-dontwarn com.google.ads.** # Temporary workaround for v6.2.1. It gives a warning that you can ignore
# Add any classes the interact with gson
-keep class com.revicostudio.gravityrun.playerdata.PlayerData
-keep class com.revicostudio.gravityrun.playerdata.SettingsDescriptor
-keep class com.revicostudio.gravityrun.playerdata.ShipStatus
-keep class com.revicostudio.gravityrun.descriptors.ShipDescriptor
-keep class com.revicostudio.gravityrun.descriptors.Ships
-keep class com.revicostudio.gravityrun.game.galaxies.Galaxies
-keep public class com.badlogic.** {*;}
