Android 安卓：Proguard在跟我捣乱

我来这里是因为我花了几个小时来解决proguard的问题

我可以生成调试apk而没有任何错误，而使用proguard它有很多错误

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

现在通过这些设置，我得到以下错误： （proguard-rules.pro=空）

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

所以我在proguard-rules.pro中添加了这一行：（根据这个答案：）

现在我遇到了以下错误：

Warning:Exception while processing task java.io.IOException: Can't write
 [C:\Users\lexha\Desktop\Spaarkaart5\app\build\intermediates\transforms\proguard\release\jars\3\1f\main.jar] 
(Can't read [C:\Users\[username]\.gradle\caches\modules-2\files-2.1\com.squareup.picasso\picasso\2.5.2\7446d06ec8d4f7ffcc53f1da37c95f200dcb9387\picasso-2.5.2.jar(;;;;;;**.class)] 
(Duplicate zip entry [com/a/a/a$a.class == picasso-2.5.2.jar:com/squareup/picasso/Action$RequestWeakReference.class]))

Warning:Exception while processing task java.io.IOException: Can't write [C:\Users\lexha\Desktop\Spaarkaart5\app\build\intermediates\transforms\proguard\release\jars\3\1f\main.jar]

 (Duplicate zip entry [com/a/a/a$a.class == picasso-2.5.2.jar:com/squareup/picasso/Action$RequestWeakReference.class]))

唯一放置picasso.jar的地方是我的root\app\libs

所以我将这一行添加到build.gradle，因为我确信这是唯一的地方

-injars libs\picasso-2.5.2.jar(!META-INF/MANIFEST.MF)

这给了我以下错误：

Warning:Exception while processing task java.io.IOException: Can't write
 [C:\Users\lexha\Desktop\Spaarkaart5\app\build\intermediates\transforms\proguard\release\jars\3\1f\main.jar]

(Duplicate zip entry [com/a/a/a$a.class == picasso-2.5.2.jar:com/squareup/picasso/Action$RequestWeakReference.class]))

 (Duplicate zip entry [com/a/a/a$a.class == picasso-2.5.2.jar:com/squareup/picasso/Action$RequestWeakReference.class]))

这就是我以前犯的错误。现在我真的很困惑，我真的不知道现在该做什么

有人能帮我吗

提前感谢

尝试将此添加到您的proguard中

-useuniqueclassmembernames

#########--------Android Support--------#########
-keep class android.support.v4.app.** { *; }
-keep interface android.support.v4.app.** { *; }
-dontwarn android.support.**

#########--------Picasso Setting--------#########    
-keepattributes SourceFile,LineNumberTable
-keep class com.parse.*{ *; }
-dontwarn com.parse.**
-dontwarn com.squareup.picasso.**
-keepclasseswithmembernames class * {
    native <methods>;
}  

-使用UniqueClassMemberName
#########--------Android支持--------#########
-keep class android.support.v4.app.*{*；}
-保留android.support.v4.app接口。**{*；}
-dontwarn android.support**
#########--------毕加索的布景————————————————————————
-keepattributes源文件，LineNumberTable
-保持类com.parse.*{*；}
-dontwarn com.parse**
-dontwarn com.squareup.picasso**
-KeepClassSwithMemberNames类*{
本地人；
}  

这是因为您的应用程序中存在重复的毕加索库依赖项。移除

root\app\libs

中的jar，并在依赖项中保留或添加毕加索库：

dependencies {
  ..
  compile 'com.squareup.picasso:picasso:2.5.2'
  ..
}

---

如果你的应用build.gradle有

编译'com.squareup.picasso:picasso:2.5.2'

，请将其删除。
