我想在我的应用程序中使用proguard,我启用它但是当我想生成apk文件时,它给了我这个错误：

You must avoid such dependencies,since the program classes will
be processed,while the library classes will remain unchanged.

Warning:there were 1 unresolved references to library class members.
You probably need to update the library versions.

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.x.x"
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'
}
怎么了 ？我在这段代码中做错了什么？
谢谢
解决方法
只需在proguard上添加：
-keep class org.apache.http.** { *; }
-dontwarn org.apache.http.**
-dontwarn android.net.**
