Erreur lors de l'utilisation de proguard avec retrofit2 et rxjava

Question

Lorsque j'ai désactivé proguard, cela a fonctionné normalement mais quand je l'utilise avec proguard, il lèvera une exception java.lang.IllegalStateException: exception fatale lancée sur le thread Scheduler.Worker.

C'est mon code

private fun getData(email : String) { 
    mSubscriptions!!.add(NetworkUtil.retrofit.getProfile(email) 
      .observeOn(AndroidSchedulers.mainThread()) 
      .subscribeOn(Schedulers.io()) 
      .subscribe({ this.handleResponse(it) }, { this.handleError(it) })) 
} 
private fun handleResponse(user: List<User>) { 
    System.out.println(user.get(0).email) 
} 
private fun handleError(error: Throwable) { 
    if (error is HttpException) { 
     val gson = GsonBuilder().create() 
     try { 
      val errorBody = error.response().errorBody()!!.string() 
      val response = gson.fromJson<Response>(errorBody, Response::class.java) 
      showSnackBarMessage(response.message) 
     } catch (e: IOException) { 
      e.printStackTrace() 
     } 
    } else { 
     showSnackBarMessage("Network Error !") 
    } 
} 

Et c'est exception

j'avais test en utilisant la compilation 'com.artemzin.rxjava: ProGuard règles: 1.3.0.0' mais encore ne fonctionne pas

Answer 1

Essayez d'ajouter ceci à votre fichier proguard-rules.pro

## Retrofit 
-dontwarn retrofit2.** 
-keep class retrofit2.** { *; } 
-keepattributes Signature 
-keepattributes Exceptions 

## RxJava 
-keepclassmembers class rx.internal.util.unsafe.*ArrayQueue*Field* { 
    long producerIndex; 
    long consumerIndex; 
} 
-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef { 
    rx.internal.util.atomic.LinkedQueueNode producerNode; 
} 
-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueConsumerNodeRef { 
    rx.internal.util.atomic.LinkedQueueNode consumerNode; 
} 
-dontwarn sun.misc.Unsafe
