android实现开机自启动服务

分享到:

        android实现开机自启动可能是移动操作系统中最简单的了,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 {
	private PendingIntent mAlarmSender;
	@Override
	public void onReceive(Context context, Intent intent) {
		// 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
		mAlarmSender = PendingIntent.getService(context, 0, new Intent(context,
				RefreshDataService.class), 0);
		long firstTime = SystemClock.elapsedRealtime();
		AlarmManager am = (AlarmManager) context
				.getSystemService(Activity.ALARM_SERVICE);
		am.cancel(mAlarmSender);
		am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstTime,
				30 * 60 * 1000, mAlarmSender);
	}
}

 

        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">
    <intent-filter>
	<!-- 系统启动完成后会调用-->
	<action android:name="android.intent.action.BOOT_COMPLETED">
	</action>
    </intent-filter>
</receiver>
