编辑:要解决该问题,您需要将此行添加到proguard.cfg中并且没有错误.新行告诉Proguard忽略android.support库.
EDIT: to resolve the problem you need to add this lines to proguard.cfg and have no errors. New lines tells proguard to ignore android.support libraries.
-dontwarn android.support.v4.**
-keep class android.support.v4.** { *; }
-dontwarn android.support.v7.**
-keep class android.support.v7.** { *; }
推荐答案
在您的proguard配置中,您已注释掉了该类找不到的类:
In your proguard config, you have commented out the keep of the class that it can't find:
#-keep public class android.support.v7.widget.ShareActionProvider
您是否尝试取消注释并重新构建?
Did you try uncommenting that and building again?
由于这不能解决您的问题,请尝试尝试此处介绍的所有内容:
since that didn't solve your problem, maybe try the catch all described here:
针对v7支持库ActionBar的Android Proguard配置
具体来说,尝试添加:
-keep class android.support.v7.internal.** { *; }
-keep interface android.support.v7.internal.** { *; }
-keep class android.support.v7.** { *; }
-keep interface android.support.v7.** { *; }
然后,如果可以的话,可以使其更加具体,因为显然,这只会保留所有支持库类,甚至包括您不使用的类.
You can then make it more specific if that works, because this obviously just keeps all the support library classes, even ones you don't use.
