React native 0.61.3 android-无法更改应用程序id

我正在使用新的

npx react native init

将一个rn项目从0.59迁移到0.61.3（最新版本）

我需要更改它给android应用程序的defaut应用程序id。为此，我做了：

• 将

  manifest.xml

  中的

  package=“com.myapp”

  值更改为

  package=“mycomp.myapp”

• 将

  app/build.graddle中的
  applicationId“com.myapp”
  值更改为
  applicationId“mycomp.myapp”

• 将src包

  com/myapp/MainApplication

  更改为

  mycomp/myapp/MainApplication

• 在下面的

  \u BUCK

  文件中更改此选项（不确定它到底是什么…）：

此后，即使在成功执行

/gradlew clean

之后，当运行

npx react native run android

命令时，应用程序仍会安装，但会因以下原因崩溃：

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

在下面找到我的

npx react native info

输出：

请跑

adb reverse tcp:8081 tcp:8081

---

然后重新加载应用程序

我遇到的问题不是由于应用程序id更改引起的。这是因为使用了react native navigation+错误的java文件导入：

执行此操作后出现了相同的问题。发生了什么？与之前完全相同，没有任何更改。相同的崩溃，相同的adb日志…您使用的是react native git升级吗？您的包名是什么？

adb reverse tcp:8081 tcp:8081
