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

问题描述

我在Android Studio中生成签名的APK时遇到问题.修正所有警告后，我陷入了这一警告:

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(无此类文件或目录)

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，因为我想保持Proguard正常运行.如何解决此错误?

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')
    }
}

只要您不需要任何特殊的ProGuard配置，

应该就可以正常工作.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

然后将自定义规则放在此文件中.

Then put your custom rules in this file.
