爲什麼這與待處理的意圖崩潰的Android報警？

我有一個非常簡單的代碼，用於安排我的下一個同步操作。它在SyncAdapter中運行，擴展了AbstractThreadedSyncAdapter - 從而使用它的上下文。 PendingIntent是爲僅用於管理SyncAdapter的BroadcastReceiver「MyService」啓動的。爲什麼這與待處理的意圖崩潰的Android報警？

我只是試圖安排其在24小時內復發。

private void scheduleNextSync(Long timeFromNow) { 
    Intent intentSync = new Intent(getContext(), MyService.class); 
    intentSync.setAction(Intent.ACTION_SYNC); 
    intentSync.addCategory("android.provider.CONTACTS_STRUCTURE"); 
    intentSync.putExtra(MySyncAdapter.EXTRA_SYNC_TYPE, ""); 
    intentSync.putExtra(MySyncAdapter.EXTRA_RESOLVE_METAID, false); 

    int flags = 0; 
    int request = REQUEST_SYNC_ALL; 
    PendingIntent piSync = PendingIntent.getBroadcast(getContext(), request, intentSync, flags); 
    // 
    Log.i(TAG, "schedulePendingSync: " + piSync.toString()); 
    AlarmManager alarm = (AlarmManager) getContext().getSystemService(Activity.ALARM_SERVICE); 
    alarm.set(request, SystemClock.elapsedRealtime() + timeFromNow, piSync); 
}

日誌輸出：

你PendingIntent.getBroadcast和alarm.set使用請求REQUEST_SYNC_ALL 我無法找到固定在Alarm doc，也不是PendingIntent doc。

也許我與最新的SDK不同步:)

這是我自己的定義...是保留值嗎？我有兩個要求：100和101「REQUEST_SYNC_FIRST_TIME」或「REQUEST_SYNC_ALL。」 – mobibob 2011-01-21 09:44:11
