Question

我有一个使用actionbarsherlock的Android应用程序和libs下的下一个jar 文件夹：

android-support-v4.jar
gson-2.2.4.jar
libGoogleAnalyticsV2.jar
volley.jar

我正在尝试使用Android Studio Build＃AI-130.692269生成签名APK。我检查两个复选框“运行ProGuard”和“包含系统程序文件”

我的ProGuard路径文件proguard-project.txt如下所示：

# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
#   http://developer.android.com/guide/developing/tools/proguard.html

# Add any project specific keep options here:

# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the JavaScript interface
# class:
#-keepclassmembers class fqcn.of.javascript.interface.for.webview {
#   public *;
#}

我编辑了project.properties，现在看起来像：

# This file is automatically generated by Android Tools.
# Do not modify this file -- YOUR CHANGES WILL BE ERASED!
#
# This file must be checked in Version Control Systems.
#
# To customize properties used by the Ant build system edit
# "ant.properties", and override values to adapt the script to your
# project structure.
#
# To enable ProGuard to shrink and obfuscate your code, uncomment this (available properties: sdk.dir, user.home):
#proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt
proguard.config=/Applications/adt-bundle-mac-x86_64/sdk/tools/proguard/proguard-android.txt:proguard-project.txt

# Project target.
target=android-17
android.library=false
android.library.reference.1=../AndroidBarSherlock/actionbarsherlock

这是我得到的输出：

我是ProGuard的新手，所以欢迎任何反馈。

Answer 1

我在尝试使用joda-time库时遇到了类似的问题。

添加

packagingOptions {
    exclude 'META-INF/DEPENDENCIES'
    exclude 'META-INF/NOTICE'
    exclude 'META-INF/LICENSE'
    exclude 'META-INF/LICENSE.txt'
    exclude 'META-INF/NOTICE.txt'
}

到build.gradle中的 android 部分，错误消失了。

找到了解决方案 Duplicate files copied (Android Studio 0.4.0)

Answer 2

this url报告了类似的问题。希望它有所帮助。

BTW还要确保您使用最新版本的Android SDK ..它会为您的项目创建一个空的proguard-project.txt。

Answer 3

从版本0.9.1开始，在包装过程中发生冲突时可以包含文件：

android.packagingOptions {
    pickFirst 'META-INF/MANIFEST.MF'
}

有关详细信息，请参阅Gradle release notes。

Answer 4

将-dontwarn添加到proguard.cfg以忽略警告

Android Studio和ProGuard - 无法编写资源[META-INF / MANIFEST.MF]（重复的zip条目[volley.jar：META-INF / MANIFEST.MF]）
