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

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
........
}

Ivan Chernykh的答案对于react-native 0.67及以下是正确的 对于react-native 0.68及以上版本的新架构，只要你遵循了Ivan Chernykh提到的步骤

对于android，你必须进入app => src => main => jni文件夹

在MainApplicationTurboModuleManagerDelegate.h

以下更改

static constexpr auto kJavaDescriptor =
      "Lcom/yournewpackagename/newarchitecture/modules/MainApplicationTurboModuleManagerDelegate;";

在MainComponentsRegistry.h

 constexpr static auto kJavaDescriptor =
      "Lcom/yournewpackagename/newarchitecture/components/MainComponentsRegistry;"; 

我今天才知道这个答案，但添加这个答案是为了帮助别人。你只需要在app/build中添加一个命名空间。Gradle引用旧的名字，像这样:

defaultConfig {
  applicationId "com.mycompany.myapp"
  namespace "com.myapp"
}

然后你可以有一个bash脚本，用这样的东西改变applicationId:

function sedi {
  if [ "$(uname)" == "Linux" ]; then
    \sed -i "$@"
  else
    \sed -i "" "$@"
  fi
}

bundle_name=com.mycompany.myapp

sedi -E "s/applicationId \"[-0-9a-zA-Z._]*\"/applicationId \"${bundle_name}\"/" android/app/build.gradle

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)
