本文介绍了一个具体的Android前台服务实现案例，通过创建自定义的通知渠道并设置通知样式，展示了如何在Android O及以上版本中启动并运行前台服务。代码示例详细说明了如何使用Notification API来配置和显示前台服务的通知。

记录下写的一个前台服务demo code

import android.app.Notification;
import android.app.NotificationChannel;
import android.app.NotificationManager;
import android.app.Service;
import android.content.Context;
import android.content.Intent;
import android.graphics.BitmapFactory;
import android.graphics.Color;
import android.os.Build;
import android.os.IBinder;

import com.demo.example.R;


public class TestServices extends Service {
    private final String CHANNEL_ID = "TEST_SERVICE_ID";
    private final String CHANNEL_NAME = "渠道一";

    private final String contentSub = "小标题";
    private final String contentTitle = "标题";
    private final String contentText = "测试前台服务";
    Notification notification;
    Notification.Builder builder;

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

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {

        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            NotificationChannel chan = new NotificationChannel(CHANNEL_ID, CHANNEL_NAME, NotificationManager.IMPORTANCE_HIGH);
            chan.enableLights(true);
            chan.setLightColor(Color.RED);
            chan.setLockscreenVisibility(Notification.VISIBILITY_PUBLIC);
            NotificationManager manager = (NotificationManager) getSystemService(Context.NOTIFICATION_SERVICE);
            assert manager != null;
            manager.createNotificationChannel(chan);

            builder = new Notification.Builder(this, CHANNEL_ID);
            notification = builder
                    .setSmallIcon(R.mipmap.ic_launcher)
                    .setContentText(contentText)
                    .setSubText(contentSub)
                    .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
                    .setContentTitle(contentTitle)
                    .build();
        }
        startForeground(1, notification);
        return START_STICKY;
    }
}
