proguard - 在proguard/minify之后,AppCompat不支持当前的主题功能

Question

在构建应用程序(使用minifyEnabled为true)之后,我已经从v22.2.1更新了支持库到v23.0.0我有"AppCompat不支持当前主题功能"的例外情况:

08-23 05:46:10.168 19437 19437 E AndroidRuntime: java.lang.RuntimeException: Unable to start activity ComponentInfo{tm.alashow.dotjpg/tm.alashow.dotjpg.ui.activity.MainActivity}: java.lang.IllegalArgumentException: AppCompat does not support the current theme features
08-23 05:46:10.168 19437 19437 E AndroidRuntime:    at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:2417)
08-23 05:46:10.168 19437 19437 E AndroidRuntime:    at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:2477)
08-23 05:46:10.168 19437 19437 E AndroidRuntime:    at android.app.ActivityThread.-wrap11(ActivityThread.java)
08-23 05:46:10.168 19437 19437 E AndroidRuntime:    at android.app.ActivityThread$H.handleMessage(ActivityThread.java:1345)

调试应用程序或禁用proguard(minifyEnabled false)时,异常不会抛出.仅在启用proguard时才会抛出.

主题:

<style name="Theme.App" parent="@style/Theme.AppCompat.Light.NoActionBar">
        <item name="colorPrimary">@color/primary</item>
        <item name="colorPrimaryDark">@color/primary_dark</item>
        ...
</style>

Proguard文件:

-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }

-keep class android.support.design.widget.** { *; }
-keep interface android.support.design.widget.** { *; }
-dontwarn android.support.design.**
-keep public class * extends android.support.design.widget.CoordinatorLayout$Behavior {
    public <init>(android.content.Context, android.util.AttributeSet);
}

我已经尝试过这个问题的答案:升级到AppCompat v22.1.0并且现在获得IllegalArgumentException:AppCompat不支持当前的主题功能,我认为这不是重复的问题.

我该如何解决？当然,启用proguard

该错误消息可能会产生误导。请留意类似这样的 Proguard 警告：

Warning: org.acra.ErrorReporter: can't find referenced method 'void setLatestEventInfo(android.content.Context,java.lang.CharSequence,java.lang.CharSequence,android.app.PendingIntent)' in library class android.app.Notification
Warning: there were 1 unresolved references to library class members.
         You probably need to update the library versions.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedlibraryclassmember)

尽管存在错误，但如果存在classes.jar先前构建的文件，构建将会成功，但干净的构建将按预期失败。

就我而言，修复 Proguard 警告还删除了 AppCompat 异常。
