React Native工程修改Android包名

简介: 默认初始化的React Native工程,生成Android工程的时候,包名默认是React Native工程的名字,跟一般Android工程com.company.xxx不一样。 这时候就需要手动修改Android工程里面的包名信息: 如下: 首先修改React Native目录下的MainActivity.

默认初始化的React Native工程,生成Android工程的时候,包名默认是React Native工程的名字,跟一般Android工程com.company.xxx不一样。

这时候就需要手动修改Android工程里面的包名信息:

如下:

首先修改React Native目录下的MainActivity.java的包名,具体路径是(android/app/src/main/java/com/PROJECT_NAME/MainActivity.java

修改 package MY.COMPANY.APPID;

然后修改MainApplication.java的包名:具体路径是(android/app/src/main/java/com/PROJECT_NAME/MainApplication.java)\

修改  package MY.COMPANY.APPID;

然后修改AndroidManifest.xml里面的包名,具体路径是( android/app/src/main/AndroidManifest.xml)

修改  package = ”MY.COMPANY.APPID“

然后再修改build.gradle文件,文件路径是(android/app/build.gradle)

applicationId "MY.COMPANY.APPID"

 

然后再clean整个工程即可,在路径android文件下执行如下命令:

./gradlew clean

 

然后执行 react-native run-android 即可。

 

如果遇见如下错误信息:

Make sure you have an Android emulator running or a device connected and have
set up your Android development environment:
