浅谈AndroidService服务的高级技巧

public class FirstService extends Service {

  private static final String TAG = "FirstService";

  @Override
  public void onCreate() {
    super.onCreate();
    Log.d(TAG, "onCreate");

    //设置为前台服务
    Intent intent = new Intent(this, MainActivity.class);
    PendingIntent pendingIntent = PendingIntent.getActivity(this, 0, intent, 0);
    Notification notification = new NotificationCompat.Builder(this)
        .setContentTitle("梅西生涯最大尴尬 战法国能否破荒？")
        .setContentText("世界杯1/8决赛，法国对阵阿根廷，法国队主帅德尚将迎来80战里程碑，成为队史执教场次最多的主教练，高卢雄鸡能否保持过去40年世界杯遇南美球队不败的金身，格里兹曼能否找回最佳状态，梅西能否打破此前世界杯淘汰赛666分钟的进球荒，都是此役的关键看点。")
        .setWhen(System.currentTimeMillis())
        .setSmallIcon(R.mipmap.ic_launcher)
        .setLargeIcon(BitmapFactory.decodeResource(getResources(), R.mipmap.ic_launcher))
        .setContentIntent(pendingIntent)
        .build();
    startForeground(1,notification);
  }
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
  Log.d(TAG, "onStartCommand");

  //在子线程中来执行耗时操作
  new Thread(new Runnable() {
    @Override
    public void run() {
      //耗时操作
