AlarmManager不拨打服务

Question

我已将AlarmManager设置为重复调用服务以更新数据库。但是似乎此AlarmManager从未调用我的服务。 我将system.out投入使用，但从未在输出中打印出来。

我的MainActivity中有这段代码：

Intent intent = new Intent(getApplicationContext(), ServiceAreaAlarmReceiver.class);

final PendingIntent pIntent = PendingIntent.getBroadcast(this, ServiceAreaAlarmReceiver.REQUEST_CODE, intent, PendingIntent.FLAG_UPDATE_CURRENT);

long firstMillis = System.currentTimeMillis();

AlarmManager alarm = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE);

alarm.setInexactRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, firstMillis + 60000, 60000, pIntent);

这是我的清单：

<receiver
    android:name=".service.ServiceAreaAlarmReceiver" />

<service
    android:name=".service.UpdateDatabaseService"
    android:exported="false" />

这是我的服务：

public class ServiceAreaAlarmReceiver extends BroadcastReceiver {

    public static final int REQUEST_CODE = 12345;

    @Override
    public void onReceive(Context context, Intent intent) {

        System.out.println("got here");
        context.startService(new Intent(context, UpdateDatabaseService.class));
    }
}
