Question

我正在使用Android Studio 1.2.2并尝试使用proguard设置生成APK。但我不能这样做并得到以下错误信息。

＆＃34;任务执行失败＆＃39;：packageRelease＆＃39;。

无法计算/Users/Documents/projectX/app/build/intermediates/classes-proguard/release/classes.jar的散列＆＃34;

proguard设置很简单。

-dontshrink
-dontoptimize
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontpreverify
-verbose

gradle文件位于下方。

apply plugin: 'com.android.application'
apply plugin: 'com.google.gms.google-services'

android {
    compileSdkVersion "Google Inc.:Google APIs:22"
    buildToolsVersion "21.1.2"

    defaultConfig {
        applicationId "com.bientus.cirque.sansotong"
        minSdkVersion 15
        targetSdkVersion 22
        versionCode 1
        versionName "1.0"
//        multiDexEnabled true
    }
    buildTypes {
        debug {
            debuggable true
        }

        release {
            minifyEnabled true
            //proguardFiles 'proguard-project.txt', 'proguard.cfg'
            //proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-project.txt', 'proguard.cfg'
            proguardFiles 'proguard-project.txt'
        }
    }
}

dependencies {
        compile fileTree(dir: 'libs', include: ['*.jar'])
        compile 'com.android.support:appcompat-v7:22.0.0'
        compile "com.google.android.gms:play-services:7.5.0"
//    compile 'com.android.support:multidex:1.0.0'
}

buildscript {
    repositories {
//        mavenCentral()
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:1.2.3'
        classpath 'com.google.gms:google-services:1.3.0-beta1'
    }
}

任何人都可以提出任何想法或想法吗？非常感谢你！

Answer 1

在＆＃39; proguard-project.txt＆＃39;中设置以下内容后，它起了作用。显然应该为这个文件设置gradle。

-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

Answer 2

查看您的构建输出。你可能会在那里有proguard警告，比如你有两个共享某个类的库（具有潜在的不同版本）。

这可能会阻止proguard计算哈希值。

我在构建中同时使用openIAB和opfIAB（都使用亚马逊和谷歌IAB）时遇到了同样的问题。删除其中一个库解决了我的问题

Answer 3

OK！它很容易！只需按照以下步骤操作： build.gradle：minifyEnabled false - ＆gt; minifyEnabled是的 proguard-rules.pro：你必须添加你在项目中使用的第三个库，如piccaso等。如果你在android studio中这样做，它会拒绝这些文件。

它有效：）

Answer 4

我也遇到了问题，解决问题的最佳方法是：转到gradle控制台，看看哪里有警告，例如

警告：com.squareup.picasso.OkHttpDownloader：找不到引用的类com.squareup.okhttp.OkHttpClient

现在打开proguard规则文件并滚动到底部并添加行

-dontwarn com.squareup.okhttp.**

对于您在gradle控制台上找到的任何缺失的类，您基本上都添加了

行

-dontwarn followed by class name

希望这对每个人都有效。祝你好运！
