Question

我在v22.2.1中将支持库更新到v23.0.0，在构建app之后（minifyEnabled为true）我有“AppCompat不支持当前主题功能”例外：

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)

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：Upgraded to AppCompat v22.1.0 and now getting IllegalArgumentException: AppCompat does not support the current theme features我觉得这不是重复的问题。

我该如何解决？启用proguard，当然

错误消息可能会产生误导。留意这样的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)

虽然如果前一个版本中有classes.jar文件，构建将会成功，但是一个干净的构建将按预期失败。

在我的情况下修复Proguard警告也删除了AppCompat例外。

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