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可以正常工作并被调用,但是以某种方式找不到我的AlarmReceiver类。

引导后成功启动的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。此类存在且位于同一包中:

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,我得到以下错误:


02-03 09:22:25.344:W / ActivityManager(103):无法启动服务
意图{flg = 0x4 cmp = com.phonegap.packagename / .AlarmReceiver(有其他功能)
}: 未找到


Android清单看起来像这样

<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>


你看到一个错误?也许我忘记了什么?

谢谢

编辑:在清单中,我添加了

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


为了使OnBootReceiver正常工作。我需要类似的闹钟吗?

最佳答案

创建挂起的Intent时,不应该使用getBroadcast而不是getService吗?
