react-native 打包Android Debug/Release APK

本文详细介绍了一种手动打包Android APK的方法,包括生成签名证书、设置Gradle变量、添加签名配置及生成APK等步骤。

除了官网上介绍的生成Apk方法外,自行打包生成也可以。步骤如下:

1.生成Android签名证书

方法一:使用Android Studio生成,不建议用,打包出的App会出现闪退。

方法二:Dos下进入JDK的bin目录,运行如下命令:

keytool -genkey -alias android.keystore -keyalg RSA -validity 36500 -keystore android.keystore
(-validity 36500代表有效期天数),命令完成后,bin目录中会生成android.keystore

示例如下

C:\Program Files (x86)\Java\jdk1.8.0_121\bin>

keytool -genkey -alias android.keystore -keyalg RSA -validity 36500 -keystore d:\android.keystore

(-alias test 生成的keystore别名,-keyalg RSA 加密和数字签名的算法,-validity 36500 有效天数)

输入密钥库口令:123456
再次输入新口令:123456
您的名字与姓氏是什么?
[Unknown]:Jory
您的组织单位名称是什么?
[Unknown]:department
您的组织名称是什么?
[Unknown]: organization
您所在的城市或区域名称是什么?
[Unknown]:ChungKing
您所在的省/市/自治区名称是什么?
[Unknown]: ChungKing
该单位的双字母国家/地区代码是什么?
[Unknown]: 86
CN=Jory, OU=department, O=organization, L=ChungKing, ST=ChungKing, C=86是否正确?
[否]: y

输入 <test> 的密钥口令
(如果和密钥库口令相同, 按回车):

如果没有错误则回去查看D盘根目录下,多了android.keystore,这便是签名证书

将android.keystore拷贝到RN项目的android/app目录中

2.设置gradle变量

编辑~/.gradle/gradle.properties../android/gradle.properties(一个是全局gradle.properties,一个是项目中的gradle.properties,大家可以根据需要进行修改) ,加入如下代码:

MYAPP_RELEASE_STORE_FILE=your keystore filename 
MYAPP_RELEASE_KEY_ALIAS=your keystore alias 
MYAPP_RELEASE_STORE_PASSWORD=*****、
MYAPP_RELEASE_KEY_PASSWORD=*****


这里的应填为:

MYAPP_RELEASE_STORE_FILE=android.keyhstore
MYAPP_RELEASE_KEY_ALIAS=android.keystore
MYAPP_RELEASE_STORE_PASSWORD=123456
MYAPP_RELEASE_KEY_PASSWORD=123456

3.在gradle配置文件中添加签名配置

编辑 android/app/build.gradle文件添加如下代码:

... 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 
} 
} } ...

4.签名打包APK

DOS进入项目android目录,若生成Debug版本,则运行

./gradlew assembleDebug

若生成Release版本,则运行

./gradlew assembleRelease
提示build Successful,打包便生成。

安装包在android/app/build/outputs/apk/目录下
