java - OnBootReceiver 可以工作，但找不到 AlarmReceiver

Question

我正在尝试在启动后立即设置警报接收器。因此，我有一个应该注册警报的 OnBootReceiver。 onBootReceiver 工作并且被调用，但不知何故它找不到我的 AlarmReceiver 类。

开机后成功启动的OnBootReceiver:

public class OnBootReceiver extends BroadcastReceiver {

    private static final String TAG = "OnBootReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(TAG, "called");

        Intent i = new Intent(context, com.packagenames.AlarmReceiver.class);
        PendingIntent pi = PendingIntent.getService(context, 0, i, 0);
        AlarmManager am = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE);

        Calendar time = Calendar.getInstance();
        time.setTimeInMillis(System.currentTimeMillis());
        time.add(Calendar.SECOND, 30);

        am.setRepeating(AlarmManager.ELAPSED_REALTIME_WAKEUP, SystemClock.elapsedRealtime(), time.getTimeInMillis(), pi);

    }

}

如您所见，它配置警报尝试调用 com.packagenames.AlarmReceiver.class。这个类存在并且位于同一个包中:

public class AlarmReceiver extends BroadcastReceiver {

    private static final String TAG = "AlarmReceiver";

    @Override
    public void onReceive(Context context, Intent intent) {
        Log.i(TAG, "alarm received");
        Intent i = new Intent(context, com.packagename.DataService.class);
        i.putExtra("action", "process");
        context.startService(i);
    }

}

不幸的是，我收到以下错误:

02-03 09:22:25.344: W/ActivityManager(103): Unable to start service Intent { flg=0x4 cmp=com.phonegap.packagename/.AlarmReceiver (has extras) }: not found

Android list 如下所示

<application>

// activities etc

        <receiver
            android:name="com.phonegap.packagename.OnBootReceiver"
            android:enabled="true"
            android:exported="false"
            android:label="OnBootReceiver" >
            <intent-filter>
                <action android:name="android.intent.action.BOOT_COMPLETED" />
            </intent-filter>
        </receiver>

        <receiver
            android:name="com.phonegap.packagename.AlarmReceiver"
            android:enabled="true"
            android:label="AlarmReceiver">
            <intent-filter>
            </intent-filter>
        </receiver>

    </application>

你发现错误了吗？也许我忘记了什么？

谢谢

编辑:在 list 中，我添加了

<uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

为了使 OnBootReceiver 工作。我需要类似的闹钟吗？

在创建待处理 Intent 时，您不应该使用 getBroadcast 而不是 getService 吗？
