Android实现开机自启动可能是移动中最简单的了,我们只需要监听一个开机启动的Broadcast(广播)即可。首先写一个Receiver(即广播监听器),继承BroadcastReceiver,如下所示:
public class BootReceiver extends BroadcastReceiver {
02
private PendingIntent mAlarmSender;
03 @Override
04
public void onReceive(Context context, Intent intent) {
05
// 在这里干你想干的事(启动一个Service,Activity等),本例是启动一个定时调度程序,每30分钟启动一个Service去更新数据
06 mAlarmSender = PendingIntent.getService(context, 0, new Intent(context,
07 RefreshDataService.class), 0);
08
long firstTime = SystemClock.elapsedRealtime();
09 AlarmManager am = (AlarmManager) context
10 .getSystemService(Activity.ALARM_SERVICE);
11 am.cancel(mAlarmSender);
12 am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime,
13
30
*
60
*
1000, mAlarmSender);
14 }
15 }
接下来,我们只需要在应用程序配置文件AndroidManifest.xml中注册这个Receiver来监听系统启动事件即可,如下所示:
<receiver android:name=".service.BootReceiver">
2
<intent-filter>
3
<!-- 系统启动完成后会调用-->
4
<action android:name="android.intent.action.BOOT_COMPLETED">
5
action>
6
intent-filter>
7
receiver>
