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:
view source
print?
复制代码 代码如下:
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:
view source
print?
复制代码 代码如下:
< 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>
