1、进入android/app目录下运行；
keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
2、修改文件：android/app/gradle.properties，增加如下代码：
MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=xxxxxx
MYAPP_RELEASE_KEY_PASSWORD=xxxxxx
3、添加签名到项目里面：android/app/build.gradle
...
android {
...
defaultConfig { ... }
signingConfigs {
release {
storeFile file(MYAPP_RELEASE_STORE_FILE)
storePassword MYAPP_RELEASE_STORE_PASSWORD
keyAlias MYAPP_RELEASE_KEY_ALIAS
keyPassword MYAPP_RELEASE_KEY_PASSWORD
}
}
buildTypes {
release {
...
signingConfig signingConfigs.release
}
}
}
...4、运行打包命令：
cd android && ./gradlew assembleRelease
