实现 Android 应用在开机时自启动

[代码] BootReceiver.java

01
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
}

[代码] 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

1
<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>
