【中文标题】将 proguard 与 retrofit2 和 rxjava 一起使用时出错

【英文标题】：Error when used proguard with retrofit2 and rxjava

【问题描述】：

当我禁用proguard时，它可以正常工作，但是当我启用proguard时，它会抛出异常：

java.lang.IllegalStateException: Fatal Exception thrown on Scheduler.Worker thread.

这是我的代码：

  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 !")
    

这是个例外：

我进行了测试，使用 compile 'com.artemzin.rxjava:proguard-rules:1.3.0.0' 但它仍然无法正常工作。

【参考方案1】：

尝试将此添加到您的 proguard-rules.pro 文件中

## 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

【讨论】：

它仍然错误:(我不知道为什么我得到错误：retrofit2.adapter.rxjava.HttpException: HTTP 400 Bad Request 当我使用 proguard 时

您是否从 proguard 中排除了您的模型和请求？

天哪！我忘了 。非常感谢你 。当我花了 4 个小时时，你是我的救援，但我不知道为什么会出现这个错误 :)
