    1. 申请keyStore，执行keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000，并降生成的keystore文件放到android\app目录下

    2. 设置gradle变量，编辑\android \gradle.properties

    1. MYAPP_RELEASE_STORE_FILE=my-release-key.keystore
    2. MYAPP_RELEASE_KEY_ALIAS=my-key-alias
    3. MYAPP_RELEASE_STORE_PASSWORD=*****
    4. MYAPP_RELEASE_KEY_PASSWORD=*****
    1. 添加签名到应用的gradle配置文件
      编辑你工程目录下的android/app/build.gradle
    1. defaultConfig { ... }
    2. signingConfigs {
    3.     release {
    4.         storeFile file(MYAPP_RELEASE_STORE_FILE)
    5.         storePassword MYAPP_RELEASE_STORE_PASSWORD
    6.         keyAlias MYAPP_RELEASE_KEY_ALIAS
    7.         keyPassword MYAPP_RELEASE_KEY_PASSWORD
    8.     }
    9. }
    10. buildTypes {
    11.     release {
    12.         signingConfig signingConfigs.release
    13.     }
    14. }

    1. 生成assets目录几js打包文件，参照上节

    2. 进入android目录，执行gradlew assembleRelease，打包成功后会在 android\app\build\outputs\apk内找到app-release.apk

    3. 安装命令gradlew installRelease
