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topackage="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
    Process: mycomp.myapp, PID: 30576

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：

Looking for JS files in

/Users/thomasfetiveau/wksp_myapp/myapp-rn61 

Loading dependency graph, done.

知道为什么吗？

在我的npx react-native info输出下面找到：

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 更改造成的。这是由于使用了反应原生导航+错误的java文件导入：https ://github.com/wix/react-native-navigation/issues/5617
