我正在尝试将Firebase Crashlytics集成到我在Android Studio 3.1.4中的当前项目中。第一次强制执行FirebaseCrash.report时，我将其记录在日志中：

最后，这是我强加的错误：

有人知道这里发生了什么吗？我是Firebase的新手，不知道该怎么走。

我猜该问题与单击“工具/ Firebase /崩溃报告”时看到的说明有关，特别是步骤5。它告诉我通过将其添加到gradle文件中来对Proguard进行模糊处理。

debug {
minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'),
'proguard-rules.pro'
}

问题是它没有告诉我gradle文件或该文件中的WHERE放置此代码。有人可以启发我吗？另外，我如何向Android Studio人员发送请求，以澄清这些说明，以便下一个人不会遇到完全相同的问题？

我对Android Studio和Gradle都是陌生的，因此对我来说，放置此代码的正确位置对在此环境中经验丰富的开发人员而言并不遥不可及。我猜想它会进入应用程序级别的Gradle.build，但是我不确定它是否在android {}参数组内，还是在android {}和Dependecies {}之间。我可以花几个小时通过反复试验来解决这个问题。...

1 个答案:

答案 0 :(得分：0)

假设您只想在应用的发行版中混淆代码（这是最常见的情况），以下几行

debug {
  minifyEnabled true 
  proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
}

应包含在

中 
android{
  buildTypes {
    release {
         <here>
    }
  }
}

位于应用程序的级别build.gradle文件中。

但是，通过查看堆栈跟踪，看来您有遗漏的依赖关系问题，应该在混淆代码之前解决（这是可选的，尤其是如果您经验不足的话）。
