Kotlin的视图绑定扩展在65k方法限制之后停止工作
达到65k方法限制后，Kotlin的视图绑定扩展停止工作，并在引用视图时抛出NullPointerException。
我试图安装MultiDex，但没有解决问题。
我正在使用Android API 25，不使用ProGuard并编译调试风格。 我能做什么？
这是一个错误的例子

这是我的应用程序实现
class App : Application() { override fun onCreate() { super.onCreate() MultiDex.install(this) // Other configs like LeakCanary, Firestore and RxJavaErrorHandler } }
清理项目解决了这个问题。
