uniapp 如何引入 Native.js

在 uni-app 中引入 Native.js 可以通过如下步骤来实现:
1. 首先在项目根目录下创建一个 `native.js` 文件,用于定义 Native.js 的相关方法和属性。
2. 在 `main.js` 文件中引入 `native.js` 文件,并且将其挂载到 Vue 实例的原型上,以便在组件中使用。
```javascript
import Vue from 'vue'
import App from './App'
import Native from './native.js'
Vue.prototype.$native = Native
Vue.config.productionTip = false
App.mpType = 'app'
const app = new Vue({
...App
})
app.$mount()
```
3. 在组件中使用 Native.js 方法或属性,需要通过 `$native` 进行调用。
```javascript
export default {
mounted() {
// 调用 Native.js 中的方法
this.$native.showToast('Hello World')
}
}
```
以上是在 uni-app 中引入 Native.js 的基础步骤,具体使用还需要根据 Native.js 的具体实现方式进行调整。

uniapp如何用native.js调用startForeground开启前台服务
在 uni-app 中,可以通过 uni.requireNativePlugin 方法调用 native.js 中的方法。具体步骤如下:
1. 在 uni-app 项目中创建 Native 模块,用于调用 native.js 中的方法:
```javascript
const nativeModule = uni.requireNativePlugin("NativeModule");
```
2. 在 Native 模块中定义调用 startForeground 方法的函数:
```javascript
function startForeground() {
nativeModule.startForeground();
}
```
3. 在 native.js 中实现 startForeground 方法,同样需要导入相关的 Android 类:
```javascript
const Context = require("@android/context");
const Notification = require("@android/app/Notification");
const NotificationManagerCompat = require("@android/app/NotificationManagerCompat");
const NotificationChannel = require("@android/app/NotificationChannel");
function startForeground() {
const service = getContext().getService();
const channel = new NotificationChannel("channel_id", "channel_name", NotificationManagerCompat.IMPORTANCE_HIGH);
const notificationManager = NotificationManagerCompat.from(Context);
const notification = new Notification.Builder(Context, "channel_id")
.setSmallIcon(android.R.drawable.ic_dialog_info)
.setContentTitle("Foreground Service")
.setContentText("Service is running in foreground")
.build();
service.startForeground(1, notification);
}
```
4. 在 Native 模块中调用 startForeground 方法:
```javascript
function startForeground() {
nativeModule.startForeground();
}
```
这样就可以通过 uni-app 调用 native.js 中的 startForeground 方法开启前台服务了。
