【问题讨论】：

  • Here is the answer - 诀窍是在您进行更改后强制完全重建您的应用程序。
  • -keep class android.support.design.widget.AppBarLayout$ScrollingViewBehavior {*;}

标签： android gradle android-gradle-plugin android-design-library android-proguard


【解决方案1】：

在您的项目文件夹中有一个名为 proguard-rules.pro 的文件，您所要做的就是在该文件中包含这一行

#For design support library
-keep class android.support.design.widget.** { *; }
-keep interface android.support.design.widget.** { *; }

现在在您应用的 gradle 文件中启用 proguard 以进行这样的调试构建

debug {
            minifyEnabled true
            proguardFiles getDefaultProguardFile('proguard-android.txt'), 'proguard-rules.pro', 'jackson-rules.pro'
        }

minifyEnabled true 启用 proguard 以进行调试构建。在测试您的 proguard 配置后，确保将标志设置为 false！

【讨论】：

  • minifyEnabled true 调试不是一个好主意，除非您知道自己在做什么，因为它会增加构建时间。另外，它不会解决 OPs 问题。
  • 这绝对不是一个好主意。但我通过添加上述 pro-guard 规则解决了这个问题。
