实现 Android 应用在开机时自启动

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);
    }
}

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

<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>
