我遇到了这次崩溃，支持库 23.0.1

显示对话框 fragment 时会发生这种情况。

它使用 android.support.v4.app.DialogFragment 和 android.support.v7.app.AppCompatDialogFragment 进行验证

还有其他人遇到过这种情况吗？

它总是发生在发布编译(启用了 Proguard)中，并且仅在某些情况下发生在调试编译中。

我正在报告两个 fragment 类的崩溃堆栈。

android.support.v4.app.DialogFragment 的堆栈:

最佳答案

根据 this如果您使用的是 appcompat-v7，您的混淆器设置应包含以下规则:

-keep public class android.support.v7.widget.** { *; }
-keep public class android.support.v7.internal.widget.** { *; }
-keep public class android.support.v7.internal.view.menu.** { *; }

-keep public class * extends android.support.v4.view.ActionProvider {
    public <init>(android.content.Context);
}

这也将使您在使用 SearchView 和我想象的其他东西时免于麻烦。
