        transitive = true
    }
    compile('com.mikepenz:aboutlibraries:5.7.0@aar') {
        transitive = true
    }
}

此异常仅在签名的 apk 中引发。安装未签名的 apk 时没有引发错误。从搜索看来，解决方案是修改 proguard-rules.pro 但不幸的是我不知道该怎么做。请帮忙。 谢谢

Answer 1

看起来下面的类被混淆了，但是被一些布局引用了：

muhammad.ibrahim.alkady.al_quran_al_kareem.radio.widget.MiniMediaController

你可以这样保持：

-keep class muhammad.ibrahim.alkady.al_quran_al_kareem.radio.widget.MiniMediaController

也许最好将所有视图类保留在小部件包中（连同它们的公共方法）：

-keep class muhammad.ibrahim.alkady.al_quran_al_kareem.radio.widget.** extends android.view.View {
   public <methods>;
}

Answer 2

将 MiniMediaController 类的构造函数从 protected 更改为 public 可以解决有或没有 pro-guard 规则的问题。
