在android studio中的android – proguard错误

我想使用proguard为我的应用程序,我启用它,但是当我想要生成apk文件,它给了我这个错误:

我正在使用最新版本的sdk 23,这是我的gradle文件:

  apply plugin: 'com.android.application' android { compileSdkVersion 23 buildToolsVersion '23.0.0' defaultConfig { applicationId "com.xx" minSdkVersion 11 targetSdkVersion 23 } buildTypes { release { minifyEnabled true proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.txt' } } } dependencies { compile 'com.android.support:appcompat-v7:23.0.0' compile 'com.android.support:recyclerview-v7:23.0.0' compile files('libs/acra-4.5.0.jar') compile files('libs/universal-image-loader-1.8.4-with-sources.jar') compile files('libs/org.apache.http.legacy.jar') compile 'com.android.support:cardview-v7:23.0.0' compile 'jp.wasabeef:recyclerview-animators:1.2.2' compile 'com.android.support:design:23.0.0' } 

哪里不对 ? 在这个代码中我做错了吗?

谢谢

只要在proguard上加上这个:

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

正如你的logcat检查http://proguard.sourceforge.net/manual/troubleshooting.html#duplicateclass

您的应用程序依赖项中有重复的类定义,这只是警告。

现在如果你想修复它,请在你的proguard-android.txt文件中添加下面的代码:

 # 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: -dontwarn com.google.code.** -dontwarn org.apache.** -dontwarn jp.wasabeef.recyclerview.** -dontwarn com.nostra13.universalimageloader.** -dontwarn org.acra.** #wasabeef recyclerview -keep class jp.wasabeef.recyclerview.** { *; } -keepattributes Signature #HTTP Legacy -keep class org.apache.** { *; } -keepattributes Signature #Universal Image Loader -keep class com.nostra13.universalimageloader.** { *; } -keepattributes Signature #Acra -keep class org.acra.** { *; } -keepattributes Signature #Support libraries -keep class com.android.** { *; } -keepattributes Signature # Keep the annotations -keepattributes *Annotation* -allowaccessmodification -keepattributes *Annotation* -renamesourcefileattribute SourceFile -keepattributes SourceFile,LineNumberTable -repackageclasses '' -dontnote com.android.vending.licensing.ILicensingService # Explicitly preserve all serialization members.

注意 :proguard-android.txt位置 – > android-sdk-path \ tools \ proguard

谢谢。!!
