Mon dossier de garde pro est la suivante

et le modèle est

@Parcel @Keep 
public class LoginRequest { 

static Gson gson = new GsonBuilder().setPrettyPrinting().create(); 

@SerializedName("username") 
@Expose 
String username; 
@SerializedName("password") 
@Expose 
String password; 

public LoginRequest(){ 

} 

/** 
* 
* @return 
* The username 
*/ 
public String getUsername() { 
    return username; 
} 

/** 
* 
* @param username 
* The username 
*/ 
public void setUsername(String username) { 
    this.username = username; 
} 

/** 
* 
* @return 
* The password 
*/ 
public String getPassword() { 
    return password; 
} 

/** 
* 
* @param password 
* The password 
*/ 
public void setPassword(String password) { 
    this.password = password; 
} 

@Override 
public String toString() { 
    return gson.toJson(this); 
} 
} 

Si je minifyEnabled vrai Dans mon fichier Gradle, la requête est une chaîne vide comme { } lorsque j'appelle la méthode toString() de la classe. J'ai essayé toutes les solutions possibles mais pas de chance.

Essayez d'ajouter la ligne suivante à vos règles ProGuard:

-keep class com.google.gson.** { *; }
