Question

自从我添加了最新材料库的依赖关系以来，我的应用程序在启动时崩溃：

implementation 'com.google.android.material:material:1.1.0-alpha06'

这仅在我使用minifyEnabled true测试时发生。没有它就可以正常工作。

崩溃日志在下面-它似乎从未接触过我的代码，显然甚至在崩溃之前就崩溃了。

我猜材料库使用反射，并且我需要在Proguard规则文件中添加更多规则。我可以从mdc-android repository中找到这些，但它们尚未解决问题：

# MaterialComponentsViewInflater inflates Material Components rather than their AppCompat counterparts.
-keep class com.google.android.material.theme.MaterialComponentsViewInflater { *; }


# CoordinatorLayout resolves the behaviors of its child components with reflection.
-keep public class * extends androidx.coordinatorlayout.widget.CoordinatorLayout$Behavior {
    public <init>(android.content.Context, android.util.AttributeSet);
    public <init>();
}

# Make sure we keep annotations for CoordinatorLayout's DefaultBehavior
-keepattributes RuntimeVisible*Annotation*

非常感谢您提供解决此问题的帮助！

当minifyEnabled启用时，使用Material Components 1.1.0-alpha06启动时应用崩溃
