react原生apk不适用于android设备

Question

这是我的第一个react原生项目，它非常简单，只有两个屏幕。这两个模块在生产中都运行良好。我使用expo的工作流程很简单。

adb-logcat是这样的：-

我不知道是什么原因导致了这个错误。请帮助

我的包.json看起来像这样：

我们也遇到过这个问题，请检查您是否在MainActivity.java:中更改了android项目名称

@Override protected String getMainComponentName() { return "YOUR_PROJECT_NAME" }

在MainActivity.java、settings.gradle、.project、AndroidManifest.xml和注册应用程序的入口文件中检查它是否相同：

AppRegistry.registerComponent('YOUR_PROJECT_NAME', () => App);
