Android - 使用Android Studio和Gradle的httpcore和httpmime的Proguard

Question

我正在开发一个应用程序，使用Android库1.0.2和Gradle 1.0.0，对于多部分实体使用Apache库httpmime和httpcore。这里是我的build.gradle：

apply plugin: 'com.android.application' 

android { 
    compileSdkVersion 21 
    buildToolsVersion "21.1.1" 

    // Something wrong with the http* libs 
    packagingOptions { 
     exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
     exclude 'META-INF/DEPENDENCIES.txt' 
     exclude 'META-INF/LICENSE.txt' 
     exclude 'META-INF/NOTICE.txt' 
     exclude 'META-INF/NOTICE' 
     exclude 'META-INF/LICENSE' 
     exclude 'META-INF/DEPENDENCIES' 
     exclude 'META-INF/notice.txt' 
     exclude 'META-INF/license.txt' 
     exclude 'META-INF/dependencies.txt' 
     exclude 'META-INF/LGPL2.1' 
    } 

    defaultConfig { 
     // ... 
    } 

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

} 

dependencies { 
    compile fileTree(dir: 'libs', include: ['*.jar']) 
    compile "com.android.support:support-v4:21.0.2" 
    compile 'org.apache.httpcomponents:httpcore:4.3.2' 
    compile 'org.apache.httpcomponents:httpmime:4.3.5' 
    compile 'net.hockeyapp.android:HockeySDK:3.5.0' 
} 

软件本身和“正常”发布的APK做工精细，但当我试图使用的ProGuard我收到以下错误信息：

按照错误消息中给出的有关重复类定义和库类的链接取决于程序类我应该在我的proguard-rules.pro中使用类似-injars ...或-libraryjars ...的内容。但由于我使用远程库而不是.jar文件，我不知道如何使用这些proguard选项。

所以我用Google搜索我的问题的解决方案，并发现了几个可能性：

• 我下载的广口瓶，将它们添加到我的\app\libs文件夹，并添加选项-libraryjar和/或-injar两个罐子，但没有组合可以工作：无论是找不到或读取文件，或者我得到一个错误，其中一个库将被处理两次。

• 我也尝试过的-keep class org.apache.**各种组合，-keep interface org.apache.**，-keep public class org.apache.** {*;}，-keepnames class org.apache.** {*;}带或不带{*;}但他们没有工作。

• 我也试过-dontwarn org.apache.**或-dontwarn org.apache.http.**选项，创建APK过程中给了我没有错误，但是当我尝试建立使用http *库的应用程序，该应用程序崩溃的东西，如一个NoSuchMethodException互联网连接。

所以我的问题是：有没有一种方法使用远程库和proguard？或者，至少可以通过在我的\ libs文件夹中包含.jars文件？

非常感谢您

Answer 1

好吧，我使用这样

-dontwarn org.apache.commons.** 
-keep class org.apache.http.** { *; } 
-dontwarn org.apache.http.** 

而且我使用的jar编译在我的库从行家使用文件夹

compile files('libs/httpmime-4.3.5.jar') 
compile files('libs/httpclient-4.3.5.jar') 
compile files('libs/httpclient-cache-4.3.5.jar') 
compile files('libs/httpcore-4.3.2.jar') 

，而不是
