关于Failed resolution of: Landroid/view/View$OnUnhandledKeyEventListener 解决方案

使用AndroidStudio开发的问题遇到一个不可思议的问题：

AndroidX的解决方案：

configurations.all {
    resolutionStrategy.eachDependency { DependencyResolveDetails details ->
        def requested = details.requested
        if (requested.group == "androidx.appcompat") {
            if (!requested.name.startsWith("multidex")) {
                details.useVersion "1.+"
            }
        }
    }
}

非AndroidX解决方案如下：

    configurations.all {
        resolutionStrategy.eachDependency { DependencyResolveDetails details ->
            def requested = details.requested
            if (requested.group == "com.android.support") {
                if (!requested.name.startsWith("multidex")) {
                    details.useVersion "26.+"
                }
            }
        }
    }
