    } else {
        notification = new android.app.Notification.Builder(context)
            .setContentTitle("通知栏标题")
            .setContentText("这是消息的内容")
            .setWhen(new Date().getTime())
            .setSmallIcon(org.autojs.autojs.R.drawable.autojs_material)

            .build();
    }
    manager.notify(1, notification);
});
ui.cancel.on("click", () => {
    var manager = context.getSystemService(android.app.Service.NOTIFICATION_SERVICE);
    manager.cancelAll();
    // manager.cancel(1);
});

存在问题

setWhen 无效
不会显示时间，因为默认是关闭的，需要设置 .setShowWhen(true)

For apps targeting Build.VERSION_CODES.N and above, this defaults to false. For earlier apps, the default is true
翻译：
对于定位Build.VERSION_CODES.N及以上的应用程序，这默认为false。对于较早的应用程序，默认值为true.

这里的Build.VERSION_CODES.N是安卓7，也就是安卓7以上默认不显示，需要设置为true

通知不能点击，无法回到应用界面
因为没有设置ContentIntent，所以只是一个显示栏。
图标是默认的，嗯。。。。

我的代码

发送通知

notification.js

importClass("android.app.NotificationManager");
importClass("android.app.Notification");
importClass("android.app.PendingIntent");
importClass("android.content.res.Resources");
importClass("android.app.PendingIntent");


module.exports = {
    send(title,content,ticker){

        let channel_id = 'channel_id';
        var manager = context.getSystemService(android.app.Service.NOTIFICATION_SERVICE);
        var notification;
	//设置图标
        var icon = context.getResources().getIdentifier("ic_3d_rotation_black_48dp", "drawable", context.getPackageName());
	//构造Intent 用于点击跳转
        let contentIntent = PendingIntent.getActivity(context, 0,  app.intent({
            packageName: currentPackage(),
            className: currentActivity()
        }), 0);
        
        if (device.sdkInt >= 26) {
            var channel = new android.app.NotificationChannel(channel_id, title?title:"通知测试", android.app.NotificationManager.IMPORTANCE_DEFAULT);
            channel.enableLights(true);
            channel.setLightColor(0xff0000);
            channel.setShowBadge(false);
            manager.createNotificationChannel(channel);
            notification = new android.app.Notification.Builder(context, channel_id)
                .setContentTitle(title || '')
                .setContentText(content || '')
                .setWhen((new Date()).getTime())
                .setSmallIcon(icon)
                .setTicker(ticker || '')
                .setOngoing(true) // 不可被取消
                .setShowWhen(true) // 显示时间
                .setContentIntent(contentIntent); // 设置刚刚构造的Intent
        } else {
            notification = new android.app.Notification.Builder(context)
                .setContentTitle(title || '')
                .setContentText(content || '')
                .setWhen((new Date()).getTime())
                .setSmallIcon(icon)
                .setTicker(ticker || '');
        }
        manager.notify(1, notification.build());
        return {
            'manager':manager,
            'notification_builder':notification
        };
    },
    cancel(){
        var manager = context.getSystemService(android.app.Service.NOTIFICATION_SERVICE);
        manager.cancelAll();
    },
    
}

发送通知

let nn = require('./notification')
nn.send('通知','通知内容','')

更新通知

let nn = require('./notification')
var notification_retrun_obj= {}  
//发送通知
notification_retrun_obj= nn.send('正在运行中','此为前台保活，请勿手动移除该通知','')
// 更新通知
let n = notification_retrun_obj.notification_builder.setWhen((new Date()).getTime()).setContentText('此为前台保活，请勿手动移除该通知 '+(new Date()).getTime()).build()
notification_retrun_obj.manager.notify(1,n)

是如何更新通知的？

使用原来的Notification.Builder

let manager = context.getSystemService(android.app.Service.NOTIFICATION_SERVICE);
let builder = new android.app.Notification.Builder(context, channel_id)
//即 notification_retrun_obj.notification_builder

更新内容

builder.setContentText('新内容')
//即 notification_retrun_obj.notification_builder.setContentText('新内容')

再次build

let n = builder.build()
//即 notification_retrun_obj.notification_builder.build()

使用原来的id发送

manager.notify(1,n)
//即 notification_retrun_obj.manager.notify(1,n)

android-更新通知文本，而不是整个通知
