java.lang.NoSuchMethodError:没有接口方法onTransitionToIdle（）V

请告诉我，我是Android测试新手，我正在尝试修复初始导航视图测试，但我得到了错误。我只是想打开抽屉，点击菜单进入一个新的活动

java.lang.NoSuchMethodError: No interface method onTransitionToIdle()V in class Landroid/support/test/espresso/IdlingResource$ResourceCallback; or its super classes (declaration of 'android.support.test.espresso.IdlingResource$ResourceCallback' appears in /data/app/com.bellman.inecparrot.mock-2/base.apk)

下面是我正在运行的测试：

听起来ProGuard正在删除所需的一个接口。我认为您需要在Proguard配置中添加一行，如下所示：

-保留公共接口android.support.test.espresso.IdlingResource$ResourceCallback{*；}

我目前没有办法测试它，因此如果这不太正确，您需要调整它，这里有一个链接指向Proguard手册中的“保留”选项：
