新建一个类集成IntentServic

package com.example.hzx.myservice;

import android.app.IntentService;
import android.content.Intent;
import android.support.annotation.Nullable;
import android.util.Log;

/**
 * Created by hzx on 2018/11/5.
 */

public class MyIntentService extends IntentService {

    private static final String TAG = "123";

    public MyIntentService(){
        super("MyIntentService");
        Log.d(TAG,"==>MyIntentService");
    }
    @Override
    protected void onHandleIntent(@Nullable Intent intent) {
        Log.d(TAG,"==>Thread id is "+Thread.currentThread().getId());

    }
    public void onDestroy(){
        super.onDestroy();
        Log.d(TAG,"==>onDestroy");
    }

}

Activity

package com.example.hzx.myservice;

import android.app.Notification;
import android.app.PendingIntent;
import android.content.ComponentName;
import android.content.Intent;
import android.content.ServiceConnection;
import android.graphics.BitmapFactory;
import android.os.IBinder;
import android.support.v4.app.NotificationCompat;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;

public class MainActivity extends AppCompatActivity implements View.OnClickListener{

    private final String TAG = "123";
    private MyService.DownloadBinder downloadBinder;

    private ServiceConnection connetction = new ServiceConnection() {
        @Override
        public void onServiceConnected(ComponentName componentName, IBinder iBinder) {
            downloadBinder = (MyService.DownloadBinder)iBinder;
            downloadBinder.startDownload();
            downloadBinder.getProgress();
        }

        @Override
        public void onServiceDisconnected(ComponentName componentName) {

        }
    };
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        Button startService = (Button)findViewById(R.id.start_service);
        Button stopService = (Button)findViewById(R.id.stop_service);

        startService.setOnClickListener(MainActivity.this);
        stopService.setOnClickListener(MainActivity.this);

        Button bingService = (Button)findViewById(R.id.bind_service);
        Button unbindService = (Button)findViewById(R.id.unbind_service);

        bingService.setOnClickListener(MainActivity.this);
        unbindService.setOnClickListener(MainActivity.this);


        Button startIntentService = (Button)findViewById(R.id.start_intent_service);
        startIntentService.setOnClickListener(MainActivity.this);

    }

    public void onClick(View v){
        switch (v.getId()){
            case R.id.start_service:
                Log.d(TAG,"activity start_service");
                Intent startIntent = new Intent(this,MyService.class);
                startService(startIntent);
                break;
            case R.id.stop_service:
                Log.d(TAG,"activity stop_sercie");
                Intent stopIntent = new Intent(this,MyService.class);
                stopService(stopIntent);
                break;
            case R.id.bind_service:
                Log.d(TAG,"activity bind_service");
                Intent bindIntent = new Intent(this,MyService.class);
                bindService(bindIntent,connetction,BIND_AUTO_CREATE);
                break;
            case R.id.unbind_service:
                Log.d(TAG,"activity unbind_service");
                unbindService(connetction);
                break;
            case R.id.start_intent_service:
                Log.d(TAG,"activity Thread id is "+Thread.currentThread().getId());
                Intent intentService = new Intent(this,MyIntentService.class);
                startService(intentService);
                break;
                default:
                    break;
        }
    }
}

注意：
1、 需要在AndroidManifest.xml文件注册
