无法在 Android Studio 中生成已签名的 APK，因为缺少 proguard-rules.txt [英] Can't generate signed APK in Android Studio, because proguard-rules.txt is missing

问题描述

我在 Android Studio 中生成签名 APK 时遇到问题.修复所有警告后，我被困在这个警告上:

I have a problem with generating signed APK in Android Studio. After fixing all the warnings I am stuck on this one:

错误:任务:app:proguardRelease"的执行失败.java.io.FileNotFoundException:/Users/franek/Documents/Android_Studio_Melange/app/proguard-rules.txt(没有这样的文件或目录)

Error:Execution failed for task ':app:proguardRelease'. java.io.FileNotFoundException: /Users/franek/Documents/Android_Studio_Melange/app/proguard-rules.txt (No such file or directory)

我不想将 minifyEnabled 更改为 false，因为我想让 Proguard 继续工作.如何修复此错误?

I don't want to change minifyEnabled to false, because I want to keep Proguard working. How can I fix this error?

build.gradle 的一个片段:

A fragment of build.gradle:

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

推荐答案

buildTypes {
    release {
        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard-android.txt')
    }
}

应该可以正常工作，只要您不需要任何特殊的 ProGuard 配置.如果这样做，请使用原始的 proguardFiles 条目并创建文件

should work ok, as long as you don't need any special ProGuard configuration. If you do, use your original proguardFiles entry and create the file

/Users/franek/Documents/Android_Studio_Melange/app/proguard-rules.txt

/Users/franek/Documents/Android_Studio_Melange/app/proguard-rules.txt

然后将您的自定义规则放入此文件中.

Then put your custom rules in this file.
