create a new package hierarchy com.mycompany.myapp under android/app/src/main/java Copy all classes from com.myapp to com.mycompany.myapp using Android studio GUI Android studio will take care of putting suitable package name for all copied classes. This is useful if you have some custom modules and don't want to manually replace in all the .java files. Update android/app/src/main/AndroidManifest.xml and android/app/build.gradle (replace com.myapp to com.mycompany.myapp Sync the project (gradle build)

对于react应用的iOS应用，在general下使用xcode -。 对于android应用程序，打开构建。在模块级Gradle。android/app文件夹里的那个。你会发现

defaultConfig {
     applicationId com.myapp
     // ...
}
// ...

改变名称。Myapp给你任何你需要的。

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

设原App名称为:com.myApp 让新的应用程序名称:com.newname.myApp

android\app\src\main\AndroidManifest.xml

重命名xml属性:' package="com.newname.myApp"

android主要\ app \ src \ \ java \ com \ [yourAppName] \ MainActivity.java

重命名包com.myApp的第一行;来打包com.newname.myApp;

android主要\ app \ src \ \ java \ com \ [yourAppName] \ MainApplication.java

重命名第一行到包com.newname.myApp;

在类中私有静态void initializeFlipper 复述这句话:

Class<？> aClass = Class.forName（“com.myApp.ReactNativeFlipper”）;

To

Class<？> aClass = Class.forName（“com.newname.myApp.ReactNativeFlipper”）;

Android\app\build.gradle

在defaultConfig上重命名applicationId

“com.newname.myApp”

在命令行上运行: $ NPX react-native start $ NPX react-native run-android
