Bootstrap 方法返回 null - Android 在启动时立即崩溃

React Native 和 React-native-navigation 的新手。应用程序在 iOS 上运行正常，但在启动时很快抛出以下异常：

react-native-navigation/lib/android/app/source/etc 确实在第 29 行返回 null -private ReloadListener reloadListener = () -> {};

我猜我的依赖关系是错误的，但不知道如何修复。

在 ./android/build.gradle 中设置 Java 8 添加这些行

compileOptions {
    sourceCompatibility = 1.8
    targetCompatibility = 1.8
}
