服务和AlarmManager

Question

这是我想要完成的事情并且严重失败。

我需要：

- 启动服务

- 做一些任务

- 设置AlarmManager以在一段时间后再次启动服务

- 停止服务

我遇到的问题是服务正在重新启动，几乎立即被停止。我想要的是服务应该在闹钟响起后启动..

以下是代码： -

 Intent intent = new Intent(ThisService.this,
                            ThisService.class);
    PendingIntent pendingIntent = PendingIntent.getService(ThisService.this, 0,
                                    intent, PendingIntent.FLAG_CANCEL_CURRENT);
    alarmManager.cancel(pendingIntent);
    alarmManager.setRepeating(AlarmManager.RTC_WAKEUP,
                            getUpdateTime(), getUpdateTime(), pendingIntent);
     stopSelf();

Answer 1

您缺少的是广播接收器

流程应为

1. 开始服务。
2. 创建BroadCast接收器
3. 执行服务中的任务
4. 设置闹钟以触发BroadCast Recievr（再次接收bradcast接收器启动服务。）
5. 调用StopSelf会停止您的服务，可以从广播recievr
重新启动

//-----Set the alarm to trigger the broadcast reciver-----------------------------
 Intent intent = new Intent(this, MyBroadcastReceiver.class);
      PendingIntent pendingIntent = PendingIntent.getBroadcast(
        this.getApplicationContext(), 234324243, intent, 0);
      AlarmManager alarmManager = (AlarmManager) getSystemService(ALARM_SERVICE);
      alarmManager.set(AlarmManager.RTC_WAKEUP, System.currentTimeMillis()
        + (i * 1000), pendingIntent);
      Toast.makeText(this, "Alarm set in " + i + " seconds",
        Toast.LENGTH_LONG).show();

//---------------Call StopSelf here--------------------

//----------------------------------------------------------------------------------




public class MyBroadcastReceiver  extends BroadcastReceiver {
     @Override
     public void onReceive(Context context, Intent intent) {

//-----------write code to start the service--------------------------
     }

    }
