进入文件android/app/src/main/AndroidManifest.xml -

更新:

attr android:元素应用程序的标签为:

旧值- android:label="@字符串/app_name" android:label="(你想放的字符串)"

and

attr android:标签的元素活动为:

旧值- android:label="@字符串/app_name" android:label="(你想放的字符串)"

为我工作过，希望能有所帮助。

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

如果您正在使用Android Studio-

com的变化。Myapp到com.mycompany.myapp

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)

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

非常简单的方法:

cd /your/project/dir

执行如下命令:

grep -rl "com.your.app" . | xargs sed -i 's/com.your.app/com.yournew.newapp/g'

重命名文件夹

android/app/src/main/java/com/your/app

改变

android/app/src/main/java/com/yournew/newapp
