React Native Build Apk

1 React Native安卓项目打包APK

1.1 产生签名的key

先通过keytool生成key

1	keytool -genkey -v -keystore demo-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 20000

将生成的key启动到项目android/app目录下面

1	mv demo-release-key.keystore android/app/

1.2 修改android/gradle.properties文件，增加如下

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
MYAPP_RELEASE_KEY_ALIAS=my-key-alias
MYAPP_RELEASE_STORE_PASSWORD=******
MYAPP_RELEASE_KEY_PASSWORD=******

其中**为Key设置的密钥和存储密码

1.3 修改android/app/build.gradle文件中的签名配置

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
    }
  }
}

1.4 然后进入android目录执行如下

1	./gradlew assembleRelease

结束后会生成apk文件在项目相关路径下面

1	android/app/build/outputs/apk/app-release.apk

每次执行前，注意将该apk文件删除

提示：如果你需要对apk进行混淆打包编辑android/app/build.gradle：
