Voici comment il est dans la version type de construction:

release { 
      shrinkResources true 
      minifyEnabled true 
      proguardFiles getDefaultProguardFile('proguard-android.txt'), 
        'proguard-rules.pro' 
     } 

maintenant, j'ai ajouté quelques règles à proguard.txt ainsi que proguard.pro mais parfois la prise de temps pour construire et son ne se produit pas. Où dois-je ajouter les règles correctement et quelles sont les règles que j'ai besoin d'ajouter?

Voici mes dépendances:

} 

Answer 2

Vous pouvez dire gradle de ne pas laisser les classes en double (ne prennent que la première) en ajoutant ce qui suit à votre build.gradle:

jar { 
    duplicatesStrategy = DuplicatesStrategy.EXCLUDE 
}
