actionbarsherlock - Android Studio 和 ProGuard - 无法写入资源 [META-INF/MANIFEST.MF](重复的 zip 条目 [volley.jar :META-INF/MANIFEST. MF])

Question

我有一个 Android 应用程序，它使用 actionbarsherlock和库下的下一个 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。我选中了“运行 ProGuard”和“包含系统 proguard 文件”两个复选框

我的 ProGuard 路径文件 proguard-project.txt好像:

# 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:

我对 ProGuard 完全陌生，因此欢迎提供任何反馈。

Answer 1

我在尝试使用 joda-time 库时遇到了类似的问题。

通过添加

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

到 安卓 build.gradle 中的部分，错误消失了。

解决方法是在
Duplicate files copied (Android Studio 0.4.0)
