Implementation of Android auto-Start Service

Android auto-start is probably the simplest in the mobile operating system. We only need to listen to a Broadcast (Broadcast) started at the startup. First, write a Receiver (that is, a broadcast listener) that inherits BroadcastReceiver, as shown below:

Copy codeThe Code is as follows: public class BootReceiver extends BroadcastReceiver {

Private PendingIntent mAlarmSender;

@ Override

Public void onReceive (Context context, Intent intent ){

// Do what you want here (start a Service, Activity, etc.). In this example, start a scheduled scheduling program and start a Service every 30 minutes to update data.

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,

30x60*1000, mAlarmSender );

}

}

Next, we only need to register this handler in the application configuration file AndroidManifest. xml to listen to system startup events, as shown below:

Copy codeThe Code is as follows: <javaser Android: name = ". service. BootReceiver">

<Intent-filter>

<! -- Called after the system is started -->

<Action android: name = "Android. intent. action. BOOT_COMPLETED">

</Action>

</Intent-filter>
