通过Proguard(Android)发布输出失败

Question

我的应用程序在重复数据删除模式下正确运行,没有问题.但是当尝试发布应用时,请在下面遇到警告:

  Warning:android.support.v4.media.session.MediaSessionCompatApi22: can't find referenced method 'void setRatingType(int)' in library class android.media.session.MediaSession
  Warning:android.support.v4.view.accessibility.AccessibilityNodeInfoCompatApi22: can't find referenced method 'android.view.accessibility.AccessibilityNodeInfo getTraversalBefore()' in library class android.view.accessibility.AccessibilityNodeInfo

         You probably need to update the library versions.

:app:proguardRelease FAILED

FAILURE: Build failed with an exception.

在搜索中我找到了这个链接和这个链接.

所以,I changed the compileSdkVersion & targetSdkVersion from 21 to 22但不行!

其他gradle细节:

    compileSdkVersion 21
    buildToolsVersion "22.0.1"
    minSdkVersion 15
    targetSdkVersion 21 

---

buildTypes {

    debug {

        buildConfigField "String", "key", "\"value\""
    }
    release {

        minifyEnabled true
        proguardFiles getDefaultProguardFile('proguard_file.txt')

        buildConfigField "String", "key", "\"value\""

    }

}

这是我的错误或发生过其他事件!？

把它放在你的proguard文件-dontwarn android.support.v4.**
