运行后:

react-native-rename "MyApp" -b com.mycompany.myapp

确保也转到构建。Gradle在android/app/… 并重命名应用程序Id如下所示:

defaultConfig {
        applicationId:com.appname.xxx
........
}

重命名所有包名后， 来自android studio。File ->使缓存失效/重新启动可以修复这类错误

这对我很有效

我使用react-native-rename* npm包。通过

npm install react-native-rename -g

然后，从你的React Native项目的根目录，执行以下命令:

react-native-rename "MyApp" -b com.mycompany.myapp

这些信息对你很有帮助，所以仔细听……

After updating package name and changing files, don't forget to change in 
package.json and app.json file at the root directory of your react native project

否则，您将得到下面的错误

Invariant Violation: "Your new package name" has not been registered

我重命名了项目的子文件夹从:“android/app/src/main/java/MY/ app/ OLD_ID/”到:“android/app/src/main/java/MY/ app/ NEW_ID/”

然后手动切换新旧包id:

: android / app / src / main / java /我的/ app / NEW_ID / MainActivity.java:

package MY.APP.NEW_ID;

在android / app / src / main / java /我的/ app / NEW_ID / MainApplication.java:

package MY.APP.NEW_ID;

在android / app / src / main / AndroidManifest.xml:

package="MY.APP.NEW_ID"

在android/app/build.gradle中:

applicationId "MY.APP.NEW_ID"

在android / app /美元:

android_build_config(
  package="MY.APP.NEW_ID"
)
android_resource(
  package="MY.APP.NEW_ID"
)

Gradle'清理结束(在/android文件夹):

./gradlew clean

运行后:

react-native-rename "MyApp" -b com.mycompany.myapp

确保也转到构建。Gradle在android/app/… 并重命名应用程序Id如下所示:

defaultConfig {
        applicationId:com.appname.xxx
........
}
