React Native Android打包apk

按照官方的5步曲:

1.在终端里面,cd 到项目的根目录后.执行下面这行命令:

keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize  -validity 

然后终端就会让你输入口令等信息.如

2.执行第一步会在根目录下会生成一个XXXXXX.keystore的文件,直接拿到android/app下.

3.在android/gradle.properties中加入:

MYAPP_RELEASE_STORE_FILE=my-release-key.keystore

MYAPP_RELEASE_KEY_ALIAS=my-key-alias

MYAPP_RELEASE_STORE_PASSWORD=******

MYAPP_RELEASE_KEY_PASSWORD=******

******换为你刚才输入的口令.

4.在android/app/build.gradle添加下面的红色字.

def enableProguardInReleaseBuilds = true

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
    }}
    splits {
....
    }
    buildTypes {
        release {
            signingConfig signingConfigs.release
           ...
        }
    }
  .....
            }
        }
    }
}

5.终端cd 到android目录下.执行命令

./gradlew assembleRelease

等一下终端执行后显示BUILD SUCCESSFUL.

成功打好了.在项目的android/app/outputs/apk下可见刚才打好的apk包
