# 初始化项目
|
||
|
||
创建项目命令:
|
||
|
||
```bash
|
||
pnpm create expo-app@latest --template blank-typescript
|
||
```
|
||
|
||
[官网模板](https://docs.expo.dev/more/create-expo/)如下:
|
||
|
||
| 模板名称 | 描述 |
|
||
| ------------------------------------------------------------ | ------------------------------------------------------------ |
|
||
| [`default`](https://github.com/expo/expo/tree/main/templates/expo-template-default) | 默认模板,用于构建多页面应用。包含推荐工具,如 **Expo CLI**、**Expo Router** 路由库,并启用 **TypeScript** 配置。适合大多数应用。 |
|
||
| [`blank`](https://github.com/expo/expo/tree/main/templates/expo-template-blank) | 最简模板,仅安装最基本依赖,不包含导航配置。 |
|
||
| [`blank-typescript`](https://github.com/expo/expo/tree/main/templates/expo-template-blank-typescript) | 空白模板,但启用了 **TypeScript** 支持。 |
|
||
| [`tabs`](https://github.com/expo/expo/tree/main/templates/expo-template-tabs) | 启用基于文件的路由系统(Expo Router),并默认使用 **TypeScript**,适合多标签页结构的应用。 |
|
||
| [`bare-minimum`](https://github.com/expo/expo/tree/main/templates/expo-template-bare-minimum) | 带有原生目录(`android` 与 `ios`)的空白模板,创建时会自动运行 [`npx expo prebuild`](https://docs.expo.dev/workflow/prebuild)。适合需要直接修改原生代码的项目。 |
|
||
|
||
**启动项目:**
|
||
|
||
```bash
|
||
npx expo start
|
||
```
|
||
|
||
|
||
|
||
# 基础配置
|
||
|
||
## 生成基础文件
|
||
|
||
```bash
|
||
npx expo customize babel.config.js
|
||
npx expo customize metro.config.js
|
||
```
|
||
|
||
|
||
|
||
## 集成 [antfu-eslint](https://github.com/antfu/eslint-config)
|
||
|
||
可以使用快捷命令(推荐):
|
||
|
||
```bash
|
||
pnpm dlx @antfu/eslint-config@latest
|
||
```
|
||
|
||
安装:
|
||
|
||
```bash
|
||
pnpm i -D eslint @antfu/eslint-config
|
||
```
|
||
|
||
新建 `eslint.config.mjs` 文件:
|
||
|
||
```js
|
||
import antfu from '@antfu/eslint-config'
|
||
|
||
export default antfu({
|
||
stylistic: {
|
||
indent: 2, // 缩进为 2 个空格(可选 4 或 'tab')
|
||
quotes: 'single', // 使用单引号(可选 'double')
|
||
},
|
||
rules: {
|
||
'unused-imports/no-unused-imports': 'warn',
|
||
'unused-imports/no-unused-vars': 'warn',
|
||
'@typescript-eslint/no-use-before-define': 'off', // 关闭 TS 的“定义前使用”警告
|
||
'no-console': 'off', // 关闭 console 报错
|
||
},
|
||
})
|
||
```
|
||
|
||
配置 vscode 模板,修改 `.vscode/settings.json` :
|
||
|
||
> 注意安装 eslint 插件
|
||
|
||
```json
|
||
{
|
||
// Disable the default formatter, use eslint instead
|
||
"prettier.enable": false,
|
||
"editor.formatOnSave": false,
|
||
|
||
// Auto fix
|
||
"editor.codeActionsOnSave": {
|
||
"source.fixAll.eslint": "explicit",
|
||
"source.organizeImports": "never"
|
||
},
|
||
|
||
// Silent the stylistic rules in you IDE, but still auto fix them
|
||
"eslint.rules.customizations": [
|
||
{ "rule": "style/*", "severity": "off", "fixable": true },
|
||
{ "rule": "format/*", "severity": "off", "fixable": true },
|
||
{ "rule": "*-indent", "severity": "off", "fixable": true },
|
||
{ "rule": "*-spacing", "severity": "off", "fixable": true },
|
||
{ "rule": "*-spaces", "severity": "off", "fixable": true },
|
||
{ "rule": "*-order", "severity": "off", "fixable": true },
|
||
{ "rule": "*-dangle", "severity": "off", "fixable": true },
|
||
{ "rule": "*-newline", "severity": "off", "fixable": true },
|
||
{ "rule": "*quotes", "severity": "off", "fixable": true },
|
||
{ "rule": "*semi", "severity": "off", "fixable": true }
|
||
],
|
||
|
||
// Enable eslint for all supported languages
|
||
"eslint.validate": [
|
||
"javascript",
|
||
"javascriptreact",
|
||
"typescript",
|
||
"typescriptreact",
|
||
"vue",
|
||
"html",
|
||
"markdown",
|
||
"json",
|
||
"jsonc",
|
||
"yaml",
|
||
"toml",
|
||
"xml",
|
||
"gql",
|
||
"graphql",
|
||
"astro",
|
||
"svelte",
|
||
"css",
|
||
"less",
|
||
"scss",
|
||
"pcss",
|
||
"postcss"
|
||
]
|
||
}
|
||
```
|
||
|
||
## 集成 [nativewind](https://www.nativewind.dev/v5/getting-started/installation)
|
||
|
||
直接参考官网:https://www.nativewind.dev/docs/getting-started/installation
|
||
|
||
1. 安装依赖
|
||
|
||
```bash
|
||
npx expo add nativewind react-native-reanimated react-native-safe-area-context
|
||
npx expo add tailwindcss@^3.4.17 -- --save-dev
|
||
```
|
||
|
||
2. 运行 `npx tailwindcss init` 生成 `tailwind.config.js` 文件,添加配置:
|
||
|
||
```js
|
||
/** @type {import('tailwindcss').Config} */
|
||
module.exports = {
|
||
// NOTE: Update this to include the paths to all files that contain Nativewind classes.
|
||
content: ["./App.tsx", "./components/**/*.{js,jsx,ts,tsx}"],
|
||
presets: [require("nativewind/preset")],
|
||
theme: {
|
||
extend: {},
|
||
},
|
||
plugins: [],
|
||
}
|
||
```
|
||
|
||
3. 创建 `global.css` 文件:
|
||
|
||
```css
|
||
@tailwind base;
|
||
@tailwind components;
|
||
@tailwind utilities;
|
||
```
|
||
|
||
注意在全局引入
|
||
|
||
4. 修改 `babel.config.js` 文件:
|
||
|
||
> 如果没有该文件,执行 `npx expo customize babel.config.js` 命令创建。
|
||
|
||
```js
|
||
module.exports = function (api) {
|
||
api.cache(true);
|
||
return {
|
||
presets: [
|
||
["babel-preset-expo", { jsxImportSource: "nativewind" }],
|
||
"nativewind/babel",
|
||
],
|
||
};
|
||
};
|
||
```
|
||
|
||
5. 修改 `metro.config.js` 文件:
|
||
|
||
> 如果没有该文件,执行 `npx expo customize metro.config.js` 命令创建。
|
||
|
||
```js
|
||
const { getDefaultConfig } = require("expo/metro-config");
|
||
const { withNativeWind } = require('nativewind/metro');
|
||
|
||
const config = getDefaultConfig(__dirname)
|
||
|
||
module.exports = withNativeWind(config, { input: './global.css' })
|
||
```
|
||
|
||
6. 新建 `src/types/nativewind-env.d.ts` 文件:
|
||
|
||
```ts
|
||
/// <reference types="nativewind/types" />
|
||
```
|
||
|
||
7. 安装 ` react-native-css-interop` :
|
||
|
||
```bash
|
||
npx expo install react-native-css-interop
|
||
```
|
||
|
||
8. 检验是否生效
|
||
|
||
```tsx
|
||
import "./global.css"
|
||
import { Text, View } from "react-native";
|
||
|
||
export default function App() {
|
||
return (
|
||
<View className="flex-1 items-center justify-center bg-white">
|
||
<Text className="text-xl font-bold text-blue-500">
|
||
Welcome to Nativewind!
|
||
</Text>
|
||
</View>
|
||
);
|
||
}
|
||
```
|
||
|
||
如果不生效,记得修改 `tailwind.config.js` 的目标路径:
|
||
|
||
```js
|
||
/** @type {import('tailwindcss').Config} */
|
||
module.exports = {
|
||
// NOTE: Update this to include the paths to all files that contain Nativewind classes.
|
||
content: ["./src/app/_layout.tsx", "./src/components/**/*.{js,jsx,ts,tsx}"],
|
||
presets: [require("nativewind/preset")],
|
||
theme: {
|
||
extend: {},
|
||
},
|
||
plugins: [],
|
||
}
|
||
```
|
||
|
||
|
||
|
||
## 集成 [gluestack-ui](https://gluestack.io/ui/docs/home/getting-started/installation)
|
||
|
||
### 方式一:CLI
|
||
|
||
```bash
|
||
npx gluestack-ui init
|
||
```
|
||
|
||
|
||
|
||
### 方式二:Manual
|
||
|
||
**前置条件:**需要安装 `nativewind`
|
||
|
||

|
||
```
|
||
|
||
2. 从 [github](https://github.com/gluestack/gluestack-ui/tree/main/src/components/ui/gluestack-ui-provider) 复制必须的组件到 `@/components/ui/gluestack-ui-provider`。
|
||
|
||
3. 修改 `tailwind.config.js` 文件:
|
||
|
||
```bash
|
||
/** @type {import('tailwindcss').Config} */
|
||
module.exports = {
|
||
darkMode: process.env.DARK_MODE ? process.env.DARK_MODE : 'class',

||
},
|
||
},
|
||
},
|
||
}
|
||
|
||
```
|
||
|
||
4. 使用 `GluestackUIProvider` 包括着整个组件:
|
||
|
||
```tsx
|
||
// App.tsx
|
||
import { GluestackUIProvider } from '@/components/ui/gluestack-ui-provider';
|
||
import '@/global.css'; // Make sure this path is correct
|
||
|
||
export default function App() {
|
||
return (
|
||
<GluestackUIProvider>{/* Add your app code here */}</GluestackUIProvider>
|
||
);
|
||
}
|
||
```
|
||
|
||
|
||
|
||
### 安装组件测试
|
||
|
||
下载对应组件:
|
||
|
||
```bash
|
||
npx gluestack-ui add button
|
||
```
|
||
|
||
引入使用:
|
||
|
||
```tsx
|
||
import { StyleSheet, Text, View } from 'react-native'
|
||
import { SafeAreaView } from 'react-native-safe-area-context'
|
||
import { Button, ButtonText } from '@/components/ui/button'
|
||
import { GluestackUIProvider } from '@/components/ui/gluestack-ui-provider'
|
||
import '@/styles/global.css'
|
||
|
||
export default function Layout() {
|
||
return (
|
||
<GluestackUIProvider>
|
||
<SafeAreaView style={styles.container}>
|
||
<View className="flex-1 items-center justify-center bg-white">
|
||
<Text className="text-xl font-bold text-blue-500">
|
||
Welcome to Nativewind!
|
||
</Text>
|
||
<Button>
|
||
<ButtonText>你好</ButtonText>
|
||
</Button>
|
||
</View>
|
||
</SafeAreaView>
|
||
</GluestackUIProvider>
|
||
|
||
)
|
||
}
|
||
|
||
const styles = StyleSheet.create({
|
||
container: {
|
||
flex: 1,
|
||
backgroundColor: '#f5f5f5',
|
||
paddingHorizontal: 16,
|
||
}
|
||
})
|
||
|
||
```
|
||
|
||
|
||
|
||
## 集成[@expo/vector-icons](https://docs.expo.dev/guides/icons/#expovector-icons)
|
||
|
||
图标网站地址:https://icons.expo.fyi/Index
|
||
|
||
该插件默认跟着expo安装了。可以直接使用,如果没有的话,则执行命令安装:
|
||
|
||
```
|
||
npx expo install @expo/vector-icons
|
||
```
|
||
|
||
测试:
|
||
|
||
```tsx
|
||
import { View, StyleSheet } from 'react-native';
|
||
import Ionicons from '@expo/vector-icons/Ionicons';
|
||
|
||
export default function App() {
|
||
return (
|
||
<View style={styles.container}>
|
||
<Ionicons name="checkmark-circle" size={32} color="green" />
|
||
</View>
|
||
);
|
||
}
|
||
|
||
const styles = StyleSheet.create({
|
||
container: {
|
||
flex: 1,
|
||
justifyContent: 'center',
|
||
alignItems: 'center',
|
||
},
|
||
});
|
||
```
|
||
|
||
|
||
|
||
如果需要没有想要的图标,可以用下面的方式:
|
||
|
||
安装 `svg` 依赖
|
||
|
||
```bash
|
||
npx expo install react-native-svg
|
||
```
|
||
|
||
|
||
|
||
然后在components下面创建一个 `Icons.tsx` 文件,用来管理所有的图标
|
||
|
||
```tsx
|
||
import Svg, { Circle, Rect, Path } from 'react-native-svg';
|
||
|
||
interface IconProps {
|
||
size?: string | number;
|
||
color?: string;
|
||
}
|
||
|
||
// 测试图标
|
||
export const DemoIcon: React.FC<IconProps> = ({ size = 30, color = '#fff', ...rest }) => {
|
||
return (
|
||
<Svg height="50%" width="50%" viewBox="0 0 100 100" {...rest}>
|
||
<Circle cx="50" cy="50" r="45" stroke="blue" strokeWidth="2.5" fill="green" />
|
||
<Rect x="15" y="15" width={size} height={size} stroke="red" strokeWidth="2" fill="yellow" />
|
||
</Svg>
|
||
);
|
||
}
|
||
|
||
// 招聘
|
||
export const ZhaoPinIcon: React.FC<IconProps> = ({ size = 30, color = '#fff', ...rest }) => {
|
||
return (
|
||
<Svg viewBox="0 0 1024 1024" p-id="5316" width={size} height={size} {...rest}>
|
||

||
return (
|
||
<SafeAreaView style={styles.container}>
|
||
<Text style={styles.header}>Header</Text>
|
||
|
||
<Slot />
|
||
|
||
<Text style={styles.footer}>Footer</Text>
|

borderRadius: 8,
|
||
marginVertical: 8,
|
||
},
|
||
footer: {
|
||
fontSize: 16,
|
||
paddingVertical: 10,
|
||
textAlign: 'center',
|
||
backgroundColor: '#e5e7eb',
|

|
||
|
||
解决fang'an修改模板 `node_modules/react-native-iconfont-cli/templates/SingleIcon.tsx.template`:
|
||
|
||
```tsx
|
||
/* eslint-disable */
|
||
/* tslint:disable */
|
||
|
||
import React from 'react';
|
||
import type { FunctionComponent } from 'react';
|
||
import type { ViewProps } from 'react-native';
|
||
#svgComponents#
|
||
#helper#
|
||
|
||
interface Props extends Omit<GProps, 'color'>, ViewProps {
|
||
size?: number;
|
||
color?: string | string[];
|
||
}
|
||
|
||
const #componentName#: FunctionComponent<Props> = ({
|
||
size = #size#,

|
||
|
||
在 `app.json` 文件下进行配置:
|
||
|
||
```json
|
||
{
|
||
"expo": {
|
||
"scheme":"oneao",
|
||
}
|
||
}
|
||
```
|
||
|
||
然后就可以通过这个配置 从别的应用或者浏览器跳转到你的app:
|
||
|
||
```
|
||
oneao://courses/react-native
|
||
```
|
||
|
||
|
||
|
||
## [定义 src 路径别名 @](https://docs.expo.dev/guides/typescript/)

安装 `module-resolver` :
|
||
|
||
```
|
||
pnpm add -D babel-plugin-module-resolver
|
||
```
|
||
|
||
修改 `babel.config.js` :
|
||
|
||
```js
|
||
module.exports = function (api) {
|
||
api.cache(true)
|
||
return {
|
||
presets: [
|
||
['babel-preset-expo', { jsxImportSource: 'nativewind' }],
|
||
'nativewind/babel',
|
||
],
|
||
plugins: [
|
||
[
|
||
'module-resolver',
|
||
{
|
||
root: ['./src'],
|
||
alias: {
|
||
'@': './src',
|
||
},
|
||
},
|

|
||
```bash
|
||
npm install -g eas-cli
|
||
```
|
||
|
||
2. 注册并登录 Expo 账户
|
||
|
||
- 访问 https://expo.dev/ 注册账户,然后命令行登录:
|
||
|
||
```bash
|
||
expo login
|
||
```
|
||
|
||
3. 配置项目构建
|
||
|
||
- 输入以下命令,选择 Android 平台即可。
|
||
|
||
```bash
|
||
eas build:configure
|
||
```
|
||
|
||
4. 构建 Android 包
|
||
|
||
- 默认构建 AAB 包(上传 Google Play):
|
||
|
||
```bash
|
||
eas build --platform android
|
||
```
|
||
|
||
- 构建 APK(可直接安装):
|
||
|
||
```bash
|
||
eas build -p android --profile preview
|
||
```
|
||
|
||
|
||

||
## 本地打包(原生方式)
|
||
|
||
### 1. 安装 [Android Studio]( https://developer.android.com/?hl=zh-cn)
|
||
|
||
1. 下载安装
|
||
|
||
- 按照官网提示依次安装 SDK 工具和必要组件。
|
||
|
||
- 安装完成后,记住 SDK 的安装路径(例如:`D:\data\sdk`,默认位置是:`C:\Users\<你的用户名>\AppData\Local\Android\Sdk`),后续需要用到。
|
||
|
||
2. 配置环境变量
|
||
|
||
- 打开 **系统属性 → 高级 → 环境变量**。
|
||
|
||
- 在 **系统变量** 中新增:
|
||
|
||
```
|
||
变量名:ANDROID_HOME
|
||
变量值:D:\data\sdk
|
||
```
|
||
|
||
- 在 **Path** 中新增:
|
||
|
||
```bash
|
||
%ANDROID_HOME%\platform-tools
|
||
%ANDROID_HOME%\tools
|
||
%ANDROID_HOME%\tools\bin
|
||
```
|
||
|
||
- 保存设置。
|
||
|
||
3. 验证安装
|
||
|
||
- 打开命令行,执行:
|
||
|
||
```
|
||
echo %ANDROID_HOME%
|
||
```
|
||
|
||
- 如果输出 SDK 路径,则说明配置成功。
|
||
|
||
|
||
|
||
### 2. 安装 [jdk17](https://adoptium.net/zh-CN/temurin/releases?version=8&os=any&arch=any)
|
||
|
||
1. 下载安装
|
||
|
||
- 下载对应版本解压即可。
|
||
- 安装成功后,记住 jdk 的安装路径,后续需要用到。
|
||
|
||
2. 配置环境变量
|
||
|
||
- 打开 **系统属性 → 高级 → 环境变量**。
|
||
|
||
- 在 **系统变量** 中新增:
|
||
|
||
```bash
|
||
变量名:JAVA_HOME
|
||
变量值:D:\devtool\jdk\jdk-17.0.16+8
|
||
```
|
||
|
||
- 在 **Path** 中新增:
|
||
|
||
```bash
|
||
%JAVA_HOME%\bin
|
||
```
|
||
|
||
- 保存设置。
|
||
|
||
3. 验证安装
|
||
|
||
- 打开命令行,执行:
|
||
|
||
```bash
|
||
java --version
|
||
```
|
||
|
||
- 如果输出 jdk 的信息,则说明配置成功。
|
||
|
||
|
||
|
||
### 3. Expo 项目启用 [Prebuild](https://docs.expo.dev/workflow/prebuild/)
|
||
|
||
1. 生成原生项目
|
||
|
||
```bash
|
||
npx expo prebuild
|
||
```
|
||
|
||
然后执行完毕后,会生成 `android` 目录。
|
||
|
||
2. 清除并重新生成原生项目
|
||
|
||
```bash
|
||
npx expo prebuild --clean
|
||
```
|
||
|
||
会删除已有的 `android` 和 `ios` 目录,然后重新生成。
|
||
|
||
|
||
|
||
### 4. 配置 Keystore
|
||
|
||
#### 4.1 生成密钥
|
||
|
||
```bash
|
||
keytool -genkey -v -keystore android-release.keystore -alias my-key-alias -keyalg RSA -keysize 2048 -validity 10000
|
||
```
|
||
|
||
说明:
|
||
|
||
- `my-release-key.keystore`:生成的密钥文件名,可自定义路径
|
||
- `my-key-alias`:密钥别名
|
||
- `RSA`:加密算法
|
||
- `2048`:密钥长度
|
||
- `10000`:有效期(天)
|
||
|
||
#### 4.2 手动配置
|
||
|
||
修改 `android/app/build.gradle` 文件
|
||
|
||
1. 修改 `signingConfigs`
|
||
|
||
```bash
|
||
signingConfigs {
|
||
release {
|
||
storeFile file('android-release.keystore') // keystore 文件路径
|
||
storePassword '你的Keystore密码' // keystore 密码
|
||
keyAlias '你的KeyAlias' // 密钥别名
|
||
keyPassword '你的Key密码' // key 密码
|
||
}
|
||
|
||
debug {
|
||
storeFile file('debug.keystore')
|
||
storePassword 'android'
|
||
keyAlias 'androiddebugkey'
|
||
keyPassword 'android'
|
||
}
|
||
}
|
||
```
|
||
|
||
2. 在 `buildTypes` 中设置 release 使用 release 签名
|
||
|
||
```bash
|
||
buildTypes {
|
||
release {
|
||
signingConfig signingConfigs.release
|
||
}
|
||
|
||
debug {
|
||
signingConfig signingConfigs.debug
|
||
}
|
||
}
|
||
```
|
||
|
||
|
||
|
||
#### 4.3 脚本配置(推荐)
|
||
|
||
1. 在 expo 项目根目录下新增 `plugins\withAndroidSignature.js` 文件,内容如下:
|
||
|
||
```js
|
||
// plugins/withAndroidSignature.js
|
||
|
||
const { withAppBuildGradle } = require("@expo/config-plugins");
|
||
const fs = require("fs");
|
||
const path = require("path");
|
||
|
||
module.exports = function withAndroidSignature(config) {
|
||
return withAppBuildGradle(config, config => {
|
||
if (config.modResults.language === "groovy") {
|
||
config.modResults.contents = setAndroidSignature(config.modResults.contents);
|
||
} else {
|
||
throw new Error("如果不是 groovy,则无法在 app/build.gradle 中设置 signingConfigs");
|
||
}
|
||
return config;
|
||
});
|
||
};
|
||
|
||
function setAndroidSignature(appBuildGradle) {
|
||
if (!fs.existsSync(path.resolve(__dirname, "../credentials.json"))) {
|
||
console.warn("警告:没有设置正式版本的 Android Keystore 文件,因为 credentials.json 不存在。");
|
||
return appBuildGradle;
|
||
}
|
||
const info = JSON.parse(fs.readFileSync(path.resolve(__dirname, "../credentials/credentials.json"), { encoding: "utf8" }));
|
||
|
||
// 使用正则表达式插入签名信息
|
||
let output = appBuildGradle.replace(
|
||
/(signingConfigs\s*\{)/,
|
||
`$1
|
||
release {
|
||
storeFile file(${JSON.stringify(path.resolve(__dirname, "../credentials/android-release.keystore"))})
|
||
storePassword ${JSON.stringify(info.android.keystore.keystorePassword)}
|
||
keyAlias ${JSON.stringify(info.android.keystore.keyAlias)}
|
||
keyPassword ${JSON.stringify(info.android.keystore.keyPassword)}
|
||
}`,
|
||
);
|
||
|
||
// 使用正则表达式替换 signingConfig
|
||
output = output.replace(
|
||
/(release\s*\{)[^}]*?signingConfig\s+signingConfigs\.debug/s,
|
||
`$1
|
||
signingConfig signingConfigs.release
|
||
`,
|
||
);
|
||
|
||
return output;
|
||
}
|
||
```
|
||
|
||
2. 在 expo 项目根目录下新增 `/credentials/credentials.json` 文件(该文件主要是 Keystore 的信息):
|
||
|
||
```json
|
||
{
|
||
"android": {
|
||
"keystore": {
|
||
"keystorePath": "credentials/android-release.keystore", // Android keystore 文件路径
|
||
"keystorePassword": "123456", // keystore 密码
|
||
"keyAlias": "my-key-alias", // Key 别名
|
||
"keyPassword": "123456" // Key 密码
|
||
}
|
||
},
|
||
"ios": {
|
||
"provisioningProfilePath": "ios/certs/profile.mobileprovision", // iOS 描述文件路径
|
||
"distributionCertificate": {
|
||
"path": "ios/certs/dist-cert.p12", // iOS 分发证书路径
|
||
"password": "password" // 证书密码
|
||
}
|
||
}
|
||
}
|
||
```
|
||
|
||
3. 在 `app.json` 中指定这个项目级插件:
|
||
|
||
```json
|
||
{
|
||
"expo": {
|
||
"plugins": [
|
||
"./plugins/withAndroidSignature"
|
||
]
|
||
}
|
||
}
|
||
```
|
||
|
||
|
||
|
||
### 5. 打包
|
||
|
||
- 编译成 Google Play 商店用的 .aab 文件
|
||
|
||
```bash
|
||
./gradlew bundleRelease
|
||
```
|
||
|
||
- 直接安装的 .apk 文件
|
||
|
||
```bash
|
||
./gradlew assembleRelease
|
||
```
|
||
|
||
**注意:**这个时候可能会下载 `gradle` 、`apk` 等资源,网络速度可能过慢。
|
||
|
||
**解决方法:**在 `android/gradle.properties` 添加网络代理:
|
||
|
||
```bash
|
||
systemProp.http.proxyHost=127.0.0.1
|
||
systemProp.http.proxyPort=7890
|
||
systemProp.https.proxyHost=127.0.0.1
|
||
systemProp.https.proxyPort=7890
|
||
```
|
||
|
||
打包结果在 `android/app/build/outputs/apt/release` 包下。
|
||
|
||
|
||
|
||
# 打包体积优化
|
||
|
||
默认初始项目打包就有 **80MB** 左右,是因为 expo 默认将 armeabi-v7a、arm64-v8a、x86、x86_64 这些架构的包都打包进来了。
|
||
|
||
| 架构名称 | 位数 | 设备类型 | 应用场景 | 备注 |
|
||
| --------------- | ----- | ------------------------------------------ | -------------- | ------------------------------------ |
|
||
| **armeabi-v7a** | 32 位 | 老旧的 ARM 芯片手机(如部分安卓 5/6 设备) | 兼容旧设备 | 已逐渐被淘汰,但仍有少数旧机型使用 |
|
||
| **arm64-v8a** | 64 位 | 主流安卓手机(大多数真机) | ✅ 主力目标平台 | 目前最主流、性能最佳的架构 |
|
||
| **x86** | 32 位 | 早期安卓模拟器(Intel 架构) | 开发调试 | 真机几乎不会用 |
|
||
| **x86_64** | 64 位 | 现代安卓模拟器 | 开发调试 | 用于 Android Studio 模拟器或测试环境 |
|
||
|
||
## 方法1(简单)
|
||
|
||
找到 `android/gradle.properties` 文件,找到 `reactNativeArchitectures` ,根据需要删除即可
|
||
|
||
```properties
|
||
reactNativeArchitectures=armeabi-v7a,arm64-v8a,x86,x86_64
|
||
```
|
||
|
||
## 方法2(原生方法 选择更多)
|
||
|
||
在 `android/app/build.gradle` 文件中添加或修改以下配置:
|
||
|
||
```
|
||
android {
|
||
// 其他配置...
|
||
|
||
splits {
|
||
abi {
|
||
enable true // 启用按 CPU 架构拆分
|
||
reset() // 重置默认架构列表
|
||
include 'arm64-v8a', 'armeabi-v7a'
|
||
universalApk false // 是否生成包含所有架构的通用 APK(false 表示只生成分架构的独立包)
|
||
// 还有一个 exclude 配置是排除指定架构的
|
||
}
|
||
}
|
||
|
||
// 其他配置...
|
||
}
|
||
```
|
||
|
||
**说明:**
|
||
|
||
- `enable true`:启用架构拆分功能。
|
||
- `reset()`:清空默认的架构配置,避免重复。
|
||
- `include`:指定要生成的架构包,比如只打 `arm64-v8a` 和 `armeabi-v7a`。
|
||
- `universalApk false`:不生成通用包(即包含所有架构的 APK)。
|
||
|
||
**举例:**
|
||
|
||
执行打包命令后,将生成多个包,例如:
|
||
|
||
```
|
||
app-arm64-v8a-release.apk
|
||
app-armeabi-v7a-release.apk
|
||
```
|
||
|
||
每个 APK 只包含对应架构的二进制文件,体积更小。
|
||
|
||
如果把 `universalApk` 设置为 `true`,则只会生成一个:
|
||
|
||
```
|
||
app-universal-release.apk
|
||
```
|
||
|
||
这个包能在 `arm64-v8a` 和 `armeabi-v7a` 架构的设备上运行,但体积最大。
|
||
|
||
|
||
|
||
# 报错
|
||
|
||
## 检查依赖是否有误
|
||
|
||
```bash
|
||
npx expo-doctor
|
||
```
|
||
|
||
## Cannot find module 'react-native-worklets/plugin'
|
||
|
||
```bash
|
||
npx expo add react-native-worklets
|
||
```
|
||
|
||
## Filename longer than 260 characters
|
||
|
||
解决方法:
|
||
|
||
1️⃣ 启用 Windows 长路径支持
|
||
|
||
通过 **注册表**开启 Windows 对长路径(超过 260 字符)的支持:
|
||
|
||
- 路径:
|
||
|
||
```
|
||
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem
|
||
```
|
||
|
||
- 键值:`LongPathsEnabled`
|
||
|
||
- 设置为 `1` 表示开启长路径支持。
|
||
|
||
✅ 作用:允许系统和应用使用超过 260 个字符的文件路径。
|
||
|
||
2️⃣ 替换 Ninja 版本
|
||
|
||
- 旧版本 Ninja(v1.10)在 Windows 下仍然可能受路径长度限制,导致构建 `.o` 文件失败。
|
||
- 下载新版 Ninja(v1.12+)并替换 Android SDK 自带的 Ninja:
|
||
|
||
旧路径(Android SDK 自带):
|
||
|
||
```
|
||
C:\Users\<your-username>\AppData\Local\Android\Sdk\cmake\3.22.1\bin\ninja.exe
|
||
```
|
||
|
||
> 该路径可能不在这里,C盘这里是默认安装的,如果安装到其他位置的话,那么就换成具体的位置。
|
||
|
||
新 Ninja 下载地址:
|
||
👉 https://github.com/ninja-build/ninja/releases
|
||
|
||
替换后,Ninja 就可以处理更长的路径,不再报 “Filename longer than 260 characters” 错误。
