android - proguard - AppCompat 不支持 proguard/minify 后的当前主题功能

Question

我已经将支持库从 v22.2.1 更新到 v23.0.0，在构建应用程序后(使用 minifyEnabled true)我有“AppCompat 不支持当前主题功能”异常:

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$H.handleMessage(ActivityThread.java:1345)

当调试应用程序或禁用 proguard (minifyEnabled false) 时，不会抛出异常。 它仅在启用混淆器时抛出。

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>

混淆文件:

-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:Upgraded to AppCompat v22.1.0 and now getting IllegalArgumentException: AppCompat does not support the current theme features我认为这不是重复的问题。

我该如何解决？当然，启用混淆器

该错误消息可能具有误导性。注意像这样的 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，但如果存在来自先前构建的 classes.jar 文件，构建将成功，但干净的构建将按预期失败。

在我的案例中，修复 Proguard 警告也移除了 AppCompat 异常。
