Android，我的服务无法启动

Question

我一直在尝试建立一个每天从服务器获取数据的轮询系统。因此，我的计划是设置 AlarmManager，使其每天 12:00 启动我的服务，该服务会在我的服务器上查找一些信息，并根据来自服务器的数据在状态栏中显示通知。

问题是我什至无法以任何方式启动我的服务。我首先尝试在 AlarmManager 中注册一个 PendingIntent，但我的服务从未启动过。现在我只是想用 startService 启动它。

那我做错了什么？

<application android:icon="@drawable/icon" android:label="@string/app_name">
        <activity android:name=".skosexActivity"
                  android:label="@string/app_name"
                  android:theme="@android:style/Theme.NoTitleBar"
                  android:screenOrientation="portrait">
            <service android:name=".notificationService"/>
            <receiver android:name="onBootReceiver" android:enabled="true">
                <intent-filter>
                    <action android:name="android.intent.action.BOOT_COMPLETED" />
                </intent-filter>
            </receiver>
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter> 
</application>

Activity :

public class homeActivity extends Activity {

    static final boolean DEBUG = true;

    static final String TAG = "HomeActivity: ";


    @Override
    protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);

        mContext = getApplicationContext();

        //my try on AlarmManager

        AlarmManager mgr = (AlarmManager)mContext.getSystemService(Context.ALARM_SERVICE);
        Intent i = new Intent(this, notificationService.class);
        PendingIntent pi = PendingIntent.getBroadcast(mContext, 0, i, 0);

        Calendar currentTime = Calendar.getInstance();
        currentTime.set(currentTime.get(Calendar.YEAR), 
                        currentTime.get(Calendar.MONTH),
                        currentTime.get(Calendar.DAY_OF_MONTH), 14, 44);

        /*mgr.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP,
                         SystemClock.elapsedRealtime() + 10000,
                         AlarmManager.INTERVAL_DAY, pi);*/

            //my try to just start it some how...
        Intent intent = new Intent(mContext, notificationService.class);

        Log.i("HomeActivity", "Trying to service");

        startService(new Intent(notificationService.class.getName()));
    }
...

服务代码:

package se.skosex.pr.skosexp1;

import android.app.IntentService;
import android.app.Notification;
import android.app.NotificationManager;
import android.app.PendingIntent;
import android.content.Context;
import android.content.Intent;
import android.util.Log;
import android.widget.Toast;

public class notificationService extends IntentService {

    private static final int ID = 1;

    public notificationService()
    {
        super("NotificationService");
    }

    @Override
    protected void onHandleIntent(Intent intent)
    {
        Log.i("NotificationService", "It started!");

        String ns = Context.NOTIFICATION_SERVICE;
        NotificationManager mNotificationManager = (NotificationManager) getSystemService(ns);

        int icon = R.drawable.hagbard;
        CharSequence tickerText = "Kom och phesta med oss på Skövde sexmästeri kväll!";
        long when = System.currentTimeMillis();

        Notification notification = new Notification(icon, tickerText, when);

        Context context = getApplicationContext();
        CharSequence contentTitle = "Skövde Sexmästeri, test 2";
        CharSequence contentText = "Ikväll är det introdhisko och det betyder at du som nolla inte har några ursäkter att stanna hemma!";
        Intent notificationIntent = new Intent(this, eventActivity.class);
        PendingIntent contentIntent = PendingIntent.getActivity(this, 0, notificationIntent, 0);

        notification.setLatestEventInfo(this, contentTitle, contentText, contentIntent);

        mNotificationManager.notify(ID, notification);
    }

}

那么，我哪里错了？
