React Native Android打包apk

按照官方的5步曲:

1.在終端里面,cd 到項目的根目錄后.執行下面這行命令:

keytool -genkey -v -keystore my-release-key.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000

然后終端就會讓你輸入口令等信息.如

2.執行第一步會在根目錄下會生成一個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=******

******換為你剛才輸入的口令.

4.在android/app/build.gradle添加下面的紅色字.

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.終端cd 到android目錄下.執行命令

./gradlew assembleRelease

等一下終端執行后顯示BUILD SUCCESSFUL.

  成功打好了.在項目的android/app/outputs/apk下可見剛才打好的apk包
