Android Proguard问题：java.lang.RuntimeException ProGuardTransform

我一直在努力解决这个问题。我有点像Android noob，我可以处理代码，但当涉及到配置问题时，我有点不知所措。我继承了这个项目，还没有找到解决方案

我在构建APK时遇到了一个模糊的proguard问题。如果我从发布版本变体的Gradle配置中删除proguard和minifyEnabled，则APK可以正常构建，尽管它比应该的大10 mb

release {
    debuggable false
    //minifyEnabled true
    //proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt'
    signingConfig signingConfigs.release
    zipAlignEnabled true
    multiDexEnabled true
}

还有一些背景，这个项目已经有两年没有更新了，现在我更新了一些最新的工具（Gradle、Android Studio、Android 7）

我得到的警告之一是关于反对意见。那会不会导致这个proguard问题？我已经研究了一些弃用问题，但它们不是我可以快速解决的问题，所以我现在跳过它，除非有人确信这将引导我找到某种解决方案

如果你需要更多的信息，请告诉我，但我想这里已经有很多了。我没有发布proguard文件，因为我尝试使用

minifyEnabled

设置并注释掉

proguardFiles getDefaultProguardFile…

，但仍然出现错误。我可能错了，但我假设它在没有配置文件的情况下运行proguard。不管怎样，如果你也需要的话，请告诉我

下面是错误消息。 注:

1-不知道问题是从哪里来的，因为我找不到该库的踪迹，并且我已经清理了构建文件夹好几次。它必须是其中一个项目依赖项的一部分

2-***表示我删除了一些文字，以保留我为之工作的公司的名称

谢谢@Rod_Algonquin。这就是我所想的，但我甚至还不知道项目中使用的库。前几天，我浏览了其中一些，试图找出哪一个是唯一的，但我还没找到。@Rod_Algonquin，你的答案是唯一的。你为什么不把它贴出来，我会给你正确的答案？谢谢@Rod_Algonquin。这就是我所想的，但我甚至还不知道项目中使用的库。前几天，我浏览了其中一些，试图找出哪一个是唯一的，但我还没找到。@Rod_Algonquin，你的答案是唯一的。你为什么不把它贴出来，我会给你正确的答案？
