Android支持v4 22.2.0的Proguard配置

Question

在更新Gradle Android版本的依赖关系以使用com.android.support:support-v4:22.2.0本地Maven extras存储库(在SDK中)之后,Proguard开始抛出这些问题.

Warning: there were 11 unresolved references to classes or interfaces.
         You may need to add missing library jars or update their versions.
         If your code works fine without the missing classes, you can suppress
         the warnings with '-dontwarn' options.

简单地添加-dontwarn android.support.v4.**解决了问题,但我想要一个更具体/更优雅的解决方案,而不是忽略support.v4包上的所有问题

任何人都可以告诉我们应该添加哪些规则,这些类/ @接口是否由Proguard正确处理？

唯一的解决方案是你提到的,即-dontwarn android.support.v4.**.这实际上是从<path-to-android-sdk>/tools/proguard/proguard-android.txt它所说的:

# The support library contains references to newer platform versions.
# Don't warn about those in case this app is linking against an older
# platform version.  We know about them, and they are safe.
-dontwarn android.support.**
