4. 点击ok，此时签名文件已生成，点击next>Finish（这里选的是release即正式包，如果打测试包，Build Type选择releaseStaging，同时下边的配置也要放在对应的releaseStaging中）

用签名文件打包apk

1. gradle配置

• 将生成的文件复制到android/app下

• 修改项目中的gradle.properties文件，添加如下代码

MYAPP_RELEASE_STORE_FILE=appRN.jks
MYAPP_RELEASE_KEY_ALIAS=appRN_alias
MYAPP_RELEASE_STORE_PASSWORD=xizhu211
MYAPP_RELEASE_KEY_PASSWORD=xizhu211

• 修改android/app/build.gradle文件，添加如下代码

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添加

signingConfig signingConfigs.release

新版要添加matchingFallbacks

buildTypes {
        debug {
            //这行没有的话本地运行会报错，提示[CODEPUSH_KEY]不存在，因为默认[react-native run-android]运行的是debug版本
            buildConfigField "String", "CODEPUSH_KEY", '""'
            matchingFallbacks = ['release', 'releaseStaging', 'debug']
        }
        releaseStaging {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            buildConfigField "String", "CODEPUSH_KEY", '"6hiQqZTB8NoJpvxxmVJE-oXOa6jJSJt39eDX4"'
            matchingFallbacks = ['release', 'releaseStaging', 'debug']
        }
        release {
            minifyEnabled enableProguardInReleaseBuilds
            proguardFiles getDefaultProguardFile("proguard-android.txt"), "proguard-rules.pro"
            buildConfigField "String", "CODEPUSH_KEY", '"HS9QpxZ2okNt28Eqa-g_EyAj8Cl9HkKh5gDQ4"'
            matchingFallbacks = ['release', 'releaseStaging', 'debug']
        }
    }

2. 建立.sh文件，添加如下代码，执行即可。

cd android/
./gradlew assembleRelease
open app/build/outputs/apk
