我正在使用新的npx react-native init.
我需要更改它给 android 应用程序的默认应用程序 ID。为此，我做了：
- 更改to
package="com.myapp"中的值manifest.xmlpackage="mycomp.myapp" - 将
applicationId "com.myapp"值更改applicationId "mycomp.myapp"为app/build.graddle - 将 src 包更改
com/myapp/MainApplication为mycomp/myapp/MainApplication 在
_BUCK文件下面更改它（不确定它到底是什么......）：android_build_config( name = "build_config", package = "mycomp.myapp", ) android_resource( name = "res", package = "mycomp.myapp", res = "src/main/res", )
之后，即使在./gradlew clean成功运行npx react-native run-android命令后，应用程序也会安装但崩溃：
2019-10-30 15:43:26.978 30576-30743/mycomp.myapp E/AndroidRuntime: FATAL EXCEPTION: create_react_context

我们还看到 Metro 已启动并正在侦听，但调试应用程序从未访问过它：

知道为什么吗？
在我的npx react-native info输出下面找到：
$ npx react-native info
