最近在编译项目时，多次出现了 java.util.zip.ZipException: duplicate entry exception android/support/vX/.../xxx.class 异常；
该异常是由于多个 module 或 第三方库（这个是主要原因）引用了不同版本的 support 库引起的；为了解决这个问题顺带把 Android support 库和
几个第三方库的依赖关系整理如下：

1.support-v7 的依赖关系

compile ("com.android.support:appcompat-v7:$SUPPORT_APPCOMPAT_V7_VERSION"){
        exclude group:'com.android.support',module:'support-v4'
        exclude group:'com.android.support',module:'support-annotations'
        exclude group:'com.android.support',module:'support-compat'
        exclude group: 'com.android.support',module: 'support-vector-drawable'
        exclude group:'com.android.support',module:'animated-vector-drawable'
    }

compile ("com.android.support:recyclerview-v7:$SUPPORT_RECYCLERVIEW_V7"){
        exclude group:'com.android.support',module:'support-compat'
        exclude group:'com.android.support',module:'support-core-ui'
    }

2.support-v13 的依赖关系

compile ("com.android.support:support-v13:$SUPPORT_V13"){
        exclude group:'com.android.support',module:'support-core-ui'
        exclude group:'com.android.support',module:'support-core-utils'
        exclude group:'com.android.support',module:'support-fragment'
        exclude group:'com.android.support',module:'support-media-compat'

        exclude group: 'com.android.support',module: 'recyclerview-v7'
    }

3.transition 的依赖关系

compile ("com.android.support:transition:$TRANSITION_VERSION"){
        exclude group:'com.android.support',module:'support-media-compat'

        exclude group:'com.android.support',module:'animated-vector-drawable'
    }

4.design 的依赖关系

compile("com.android.support:design:$DESIGN_VERSION") {
        exclude group:'com.android.support',module:'animated-vector-drawable'
        exclude group: 'com.android.support',module: 'support-vector-drawable'
        exclude group: 'com.android.support',module: 'transition'

        exclude group:'com.android.support',module:'appcompat-v7'
        exclude group: 'com.android.support',module: 'recyclerview-v7'

    }

5.constraint 的依赖关系

compile ('com.android.support.constraint:constraint-layout:1.0.2'){
        exclude group:'com.android.support',module:'support-v4'
    }

        exclude group:'com.android.support',module:'support-v4'
    }

7.com.yuyh.imgsel（github上一图片选择器） 的依赖关系

        exclude group:'com.android.support',module: 'recyclerview-v7'
    }
