随着Android版本的更新, 又是基于安全!安全! 非系统层APP想要正大光明的或搞点小手段在后台长时间或者"永久"保活是愈发不可实现了(当然排除一些"黑技术"),大陆定制化的OS又为了更好的保证UI的流畅性也更是把此拿捏的死死的(除了QQ,微信,支付宝等这类占据市场主导地位的APP手机厂商加入了白名单).这对于一个闻不见经传的中小企业为了能让自家的智能外设能与APP之间的连接建立的长久一些, 数据通信能尽可能不出现中断, 引导用户自行设置APP后台运行和避免APP被清除已成单选项.

直接上代码

1. 首先创建一个service

package com.example.testone.service;

import android.annotation.SuppressLint;
import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.app.Service;
import android.content.Intent;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.PixelFormat;
import android.graphics.drawable.Drawable;
import android.os.Build;
import android.os.IBinder;
import androidx.core.app.NotificationCompat;

import com.example.testone.R;

import static androidx.core.app.NotificationCompat.PRIORITY_HIGH;
import static androidx.core.app.NotificationCompat.VISIBILITY_PUBLIC;

public class TestService extends Service {

    private final String CHANNEL_ONE_ID = "100";

    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public boolean onUnbind(Intent intent) {
        return super.onUnbind(intent);
    }

    @Override
    public void onCreate() {
        super.onCreate();
        /****************第一点*******************/
        //创建通知栏常驻通知
        initNotif("title", "text");
    }

    @Override
    public void onDestroy() {
        stopForeground(true);
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
//        return super.onStartCommand(intent, flags, startId);
        /****************第二点*******************/
        //返回START_STICKY,被系统或手动清理后可重启
        return START_STICKY;
    }

    public void initNotif(String title, String context) {
        NotificationManager manager = (NotificationManager) getSystemService(NOTIFICATION_SERVICE);
        //RemoteViews remoteView = new RemoteViews(getPackageName(), R.layout.RemoteView); 
        Intent nfIntent = new Intent(this, MainActivity.class);
        PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, nfIntent, PendingIntent.FLAG_IMMUTABLE);
        @SuppressLint("WrongConstant") NotificationCompat.Builder builder = new NotificationCompat.Builder(getApplicationContext(), CHANNEL_ONE_ID)
                .setContentIntent(pendingIntent) // 设置PendingIntent
                .setSmallIcon(R.mipmap.ic_launcher) // 设置状态栏内的小图标
                //.setLargeIcon(bitmapIcon)// 设置大图标
                .setContentTitle(title)
                .setContentText(context) // 设置内容
                //.setWhen(System.currentTimeMillis())// 设置该通知发生的时间
                .setVisibility(VISIBILITY_PUBLIC)// 锁屏显示全部通知
                //.setDefaults(Notification.DEFAULT_ALL)// //使用默认的声音、振动、闪光
                .setCategory(Notification.CATEGORY_SERVICE)//设置类别
                .setPriority(PRIORITY_MAX);// 优先级为：重要通知

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            //安卓8.0以上系统要求通知设置Channel,否则会报错
            NotificationChannel notificationChannel = new NotificationChannel(CHANNEL_ONE_ID, "服务常驻通知", NotificationManager.IMPORTANCE_HIGH);
            notificationChannel.setLockscreenVisibility(VISIBILITY_PUBLIC);//锁屏显示全部通知
            manager.createNotificationChannel(notificationChannel);
            builder.setChannelId(CHANNEL_ONE_ID);
        }
        Notification notification = builder.build(); // 获取构建好的Notification
        //notification.defaults = Notification.DEFAULT_SOUND; //设置为默认的声音
        notification.flags = Notification.FLAG_NO_CLEAR;//不消失的常驻通知
        startForeground(1, notification);//设置常驻通知
    }

}

2. 再创建个Service继承NotificationListenerService, 先在AndroidManifest.xml中声明，方可在MainActivity中调用方法isNotificationListenerEnabled跳转到系统设置-->获取通知使用权的应用列表里出现当前APP。

package com.example.testone.service;

import android.app.Notification;
import android.content.Intent;
import android.service.notification.NotificationListenerService;
import android.service.notification.StatusBarNotification;
import android.util.Log;

public class TestNotificationListenerService extends NotificationListenerService {

    @Override
    public void onCreate() {
        super.onCreate();
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        return super.onStartCommand(intent, flags, startId);
    }

    @Override
    public void onNotificationPosted(StatusBarNotification sbn) {
        super.onNotificationPosted(sbn);
        //Notification notification = sbn.getNotification();
        Log.d(LiveTaskApplication.TAG, "sbn.getPackageName: " + sbn.getPackageName());
    }
}

3. 创建Application

package com.example.testone.service;

import android.app.Application;
import android.content.Intent;
import android.os.Build;

public class TestApplication extends Application {

    @Override
    public void onCreate() {
        super.onCreate();
        startService();
    }

    /**
     * 启动服务
     */
    private void startService() {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            /****************第三点*******************/
            //安卓8.0以上开启为前台服务
            startForegroundService(new Intent(this, TestService.class));
        } else {
            startService(new Intent(this, TestService.class));
        }
        startService(new Intent(this, TestNotificationListenerService.class));
    }

}

4. AndroidManifest.xml中

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.testone">
    <uses-permission android:name="android.permission.INTERNET" />

    <application
        android:name=".service.TestApplication"
        android:allowBackup="true"
        android:icon="@mipmap/ic_launcher"
        android:label="@string/app_name"
        android:roundIcon="@mipmap/ic_launcher_round"
        android:supportsRtl="true"
        android:theme="@style/AppTheme">

                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <service
            android:name=".service.TestNotificationListenerService"
            android:enabled="true"
            android:exported="true"
            android:label="@string/app_name"
            android:permission="android.permission.BIND_NOTIFICATION_LISTENER_SERVICE"><!--必要的绑定权限-->
            <intent-filter>
                <action android:name="android.service.notification.NotificationListenerService" /><!--必要的action-->
            </intent-filter>
        </service>
        <service
            android:name=".service.TestService"
            android:directBootAware="true"
            android:enabled="true"
            android:exported="true"
            android:label="@string/app_name"
            android:foregroundServiceType="phoneCall|mediaPlayback|dataSync|mediaProjection|connectedDevice|location" />
    </application>

</manifest>
