Retrofit 2 n'envoie pas de données lorsque ProGuard est activé

J'essaie de connecter mes utilisateurs à l'aide de Retrofit 2. (Fondamentalement, un GET à l'URL de connexion avec un en-tête de base) Cela fonctionne bien, mais une fois que je l'ai ProGuard, l'autorisation d'en-tête n'est plus envoyée. (Voir sorties de journal)

Exemple de code:

Modèle utilisateur:

public interface UserService {

    @GET(GET_LOGIN)
    Observable<User> login(@Header("Authorization") String basic);
}

Activité de connexion:

public void onClick(View v) {
    mRetrofit.create(UserService.class)
             .login(Credentials.basic(email, password))
             .subscribeOn(Schedulers.io())
             .observeOn(AndroidSchedulers.mainThread())
             .subscribe(user -> {
                UserHelper.save(LoginActivity.this, user);
             }, throwable -> Dog.d);
}

Fichier Proguard:

# Retrofit
-dontwarn retrofit2.** 
-dontwarn org.codehaus.mojo.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*
-keepclasseswithmembers class * {
    @retrofit.* <methods>;
}

-keepclasseswithmembers interface * {
    @retrofit.* <methods>;
}

J'ai finalement réussi à le faire fonctionner. Voici la configuration proguard concernant Retrofit 2

# Retrofit
-dontwarn retrofit2.**
-dontwarn org.codehaus.mojo.**
-keep class retrofit2.** { *; }
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*

-keepattributes RuntimeVisibleAnnotations
-keepattributes RuntimeInvisibleAnnotations
-keepattributes RuntimeVisibleParameterAnnotations
-keepattributes RuntimeInvisibleParameterAnnotations

-keepattributes EnclosingMethod

-keepclasseswithmembers class * {
    @retrofit2.* <methods>;
}

-keepclasseswithmembers interface * {
    @retrofit2.* <methods>;
}

Merci @ xudshen

[~ # ~] mise à jour [~ # ~]

Le principal problème: j'ai utilisé proguard-Android-optimise donc je dois ajouter:

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

Je suis également revenu à la configuration proguard Retrofit 2 régulière fournie par square:

# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on RoboVM on iOS. Will not be used at runtime.
-dontnote retrofit2.Platform$IOS$MainThreadExecutor
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by converters and adapters.
-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy instance.
-keepattributes Exceptions

Ajout à la réponse de @ Romain Vous devez ajouter au fichier proguard

-keepclasseswithmembers class * {
    @retrofit2.http.* <methods>;
}

Si vous utilisez @Header, @Query ...

Une autre solution simple utilise @keep depuis l'annotation de support https://developer.Android.com/reference/Android/support/annotation/Keep.html

@Keep
interface APIService 
{

    @GET("/user/auth")
    fun auth(@Header(Constants.AUTHORIZATION) authorization: String): Call<User>

}

pour moi fonctionne en utilisant l'annotation @SerializedName

public class YourJsonClass{
   @SerializedName("name") String username;

   ...
 }

enfin je trouve. essayez simplement ceci si vous utilisez Gson, ajoutez ceci pour moderniser pro-guard:

-keepclassmembers,allowobfuscation class * {
  @com.google.gson.annotations.SerializedName <fields>;
}

puis utilisez @SerializedName("name") dans votre modèle .kotlin exemple:

class PaymentRequestModel (
    @SerializedName("name")
    @Expose
    var name : String = "",
}

Ajout de la compatibilité Retrofit 2 avec le code Proguard Obfuscator

    -dontwarn retrofit.**
    -keep class retrofit.** { *; }
    -keepattributes Signature
    -keepattributes Exceptions
    -dontwarn Java.lang.invoke.*
    -keep class com.elephantmobile.ui.remote.model.** { *; }
    -dontwarn retrofit.appengine.UrlFetchClient
    -keepclasseswithmembers class * {
        @retrofit.http.* <methods>;
    }
    -keepclassmembernames interface * {
        @retrofit.http.* <methods>;
    }
    -dontwarn retrofit2.Platform$Java8
