使用proguard规则排除文件

问题描述

我试图用proguard减小apk的大小。这样做时，我收到了这些warnigs消息，

 警告：无法写入资源[META-INF / LICENSE.txt] （重复的zip条目[commons-lang-2.6.jar：META-INF / LICENSE.txt]）
警告：无法写入资源[META-INF / NOTICE.txt]（重复的zip条目[commons-lang -2.6.jar：META-INF / NOTICE.txt]）
警告：无法写入资源[.readme]（重复的zip条目[classes.jar：.readme]）
  

除了保留类以外，还有什么办法排除这些文件？我已经在gradle文件中排除了这些，但这似乎并不奏效。如果您使用的是Android Studio，请添加此代码

到您的build.gradle

  packagingOptions {
排除'META-INF / LICENSE.txt'
排除'META-INF / NOTICE.txt'
排除'.README'
} 
  

///完整示例

  android {
 compileSdkVersion 23 
 buildToolsVersion '22 .0.1'
 defaultConfig {
 minSdkVersion 14 
 targetSdkVersion 22 
 versionCode 1 
 versionName'1.0'
 renderscriptTargetApi 22 
 
 buildTypes {
 debug {
 debuggable true 
 minifyEnabled false 
 renderscriptDebuggable true 
 versionNameSuffix-debug
proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules.pro'
} 
 release {
 debuggable false 
 minifyEnabled true 
 shrinkResources false 
 renderscriptDebuggable false 
 proguardFiles getDefaultProguardFile（'proguard-android.txt'），'proguard-rules.pro'
} 
} 
 packagingOptions {
 exclude'META -INF / LICENSE.txt'
排除'META-INF / NOTICE.txt'
排除'.README'
} 
 
}

I am trying to reduce the size of the apk using proguard . I am getting these warnigs messages while doing so ,

Warning: can't write resource [META-INF/LICENSE.txt] (Duplicate zip entry [commons-lang-2.6.jar:META-INF/LICENSE.txt])
Warning: can't write resource [META-INF/NOTICE.txt] (Duplicate zip entry [commons-lang-2.6.jar:META-INF/NOTICE.txt])
Warning: can't write resource [.readme] (Duplicate zip entry [classes.jar:.readme])

Apart from keeping classes is there any way to exclude these files ? I have excluded these in gradle file but that doesn't seem to work .

解决方案

if you are using Android Studio , add this

to your build.gradle

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

/// complete example

android {
    compileSdkVersion 23
    buildToolsVersion '22.0.1'
    defaultConfig {
        minSdkVersion 14
        targetSdkVersion 22
        versionCode 1
        versionName '1.0'
        renderscriptTargetApi 22
    }
    buildTypes {
        debug {
            debuggable true
            minifyEnabled false
            renderscriptDebuggable true
            versionNameSuffix "-debug"
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
        release {
            debuggable false
            minifyEnabled true
            shrinkResources false
            renderscriptDebuggable false
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro'
        }
    }
    packagingOptions {
        exclude 'META-INF/LICENSE.txt'
        exclude 'META-INF/NOTICE.txt'
        exclude '.README'
    }

}
