使用(兼容)库的android项目的Proguard

Question

我正试图通过Package Explorer Export> Export Android Application中的内置Proguard支持来使用Proguard.主项目是使用一个库项目,而该库项目又使用了android兼容库,它也使用了这个兼容性库本身.基本上是这样的:

BaseLibraryProject BaseActitivity libs:android-support-v4.jar MainProject使用库BaseLibraryProject libs:android-support-v4.jar

这个应用程序在设备和模拟器上运行正常.然而,Proguard会发出很多警告并存在代码1.

这是Proguard相关列表的最后一点:

[2012-04-09 14:19:49 - MainProject] Warning: android.support.v4.widget.SearchViewCompatHoneycomb: can't find referenced class android.widget.SearchView

[2012-04-09 14:19:49 - MainProject]          Alternatively, you may have to specify the option 
[2012-04-09 14:19:49 - MainProject]          '-dontskipnonpubliclibraryclassmembers'.
[2012-04-09 14:19:49 - MainProject] java.io.IOException: Please correct the above warnings first.

如您所见:它找不到兼容性库.

这是proguard.cfg文件的开头,包括-libraryjars和-dontskipnonpubliclibraryclassmembers:

-optimizationpasses 5
-dontusemixedcaseclassnames
-dontskipnonpubliclibraryclasses
-dontskipnonpubliclibraryclassmembers
-dontpreverify
-verbose
-libraryjars libs/android-support-v4.jar

没有区别.我尝试了将库添加到BaseLibrary项目/ MainProject的各种组合,完全限定的路径名​​.似乎没有任何帮助.

关于proguard的大多数stackoverflow问题似乎都涉及设置Ant.知道什么可能导致这个问题,以及如何让Proguard在这个使用多个库的项目上工作？

提前致谢,

ADT 17的发布为Proguard的工作方式带来了许多改进,包括更好的默认值,我认为应该解决你的支持库问题.

请参阅 - http://tools.android.com/recent/proguardimprovements

Eclipse(project.properties)

从ADT 17开始,默认的project.properties文件现在包含以下行,该行引用标准的Proguard配置文件(proguard-android.txt)和项目特定的Proguard配置文件(proguard-project.txt)...

proguard.config=${sdk.dir}/tools/proguard/proguard-android.txt:proguard-project.txt

我建议创建一个新的Android项目,看看它是如何布局的并使用这些新文件.您的应用程序将长期受益,因为Proguard和默认配置有所改进.

更新

Gradle(build.gradle)

以下将使用默认的标准proguard配置和本地项目proguard规则.

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