AlarmManager永遠不會爲BroadcastReceiver返回事件，如何調試？

下面的代碼不會引發任何錯誤，也不會起作用。當我調試addInvoiceReminder（）方法時，它顯示時間正在正確設置，並且AlarmManager被設置爲在先前設置的時間關閉。有人能看到我的缺陷嗎？我不確定爲什麼BroadcastReceiver的onRecieve事件從未觸發。AlarmManager永遠不會爲BroadcastReceiver返回事件，如何調試？

//---adds an invoice reminder when the user successfully adds a sales or expense invoice--- 
public void addInvoiceReminder() { 
    //---gets a Calendar object with current time--- 
    Calendar cal = Calendar.getInstance(); 
    //---sets the calendar object to the reminder dialog date--- 
    //cal.set(reminder_year, reminder_month, reminder_day); 
    cal.add(Calendar.SECOND, 30); 

    Intent intent = new Intent(this, DueInvoiceAlarmReceiver.class); 
    intent.putExtra("reminder", "Invoice Number: 999999 is due!");   
    PendingIntent sender = PendingIntent.getBroadcast(this, 0, intent, 0); 

    //---gets the alarm manager service set for the calendar time which is the reminder time--- 
    AlarmManager alarm_manager = (AlarmManager) getSystemService(ALARM_SERVICE); 
    alarm_manager.set(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), sender); 
} 

//---Receives the event fired when the reminder date for an invoice is passed--- 
public class DueInvoiceAlarmReceiver extends BroadcastReceiver {   
    @Override 
    public void onReceive(Context context, Intent intent) { 
     try { 
     Bundle bundle = intent.getExtras(); 
     String message = bundle.getString("reminder"); 
     Toast.makeText(context, message, Toast.LENGTH_SHORT).show(); 
     } catch (Exception e) { 
     Toast.makeText(context, "There was an error somewhere, but we still received an alarm", Toast.LENGTH_SHORT).show(); 
     e.printStackTrace();   
     } 
    }  
}

什麼不起作用？ –

BroadcastReceiver的onReceive從不觸發，我在DueInvoiceAlarmReceiver中設置了一個調試點，它從不觸發。 – AutoM8R

確保您在清單中聲明瞭廣播接收器。

謝謝，但它被宣佈。對不起，原來忘了提這個。 – AutoM8R

嘗試Calendar cal = cal .getInstance(); cal.setTimeInMillis(System.currentTimeMillis());

因爲你想接受磨的時間，但從來沒有太了。

嗯，不，因爲當我調試我看到時間設置在毫秒，這是通過「cal.getTimeInMillis（）」實現的，你可以在addInvoiceReminder（）的最後一行看到它。 – AutoM8R

但是，無論如何，仍然難住這個.. – AutoM8R

是啊我也很難過。祝你好運 – domshyra
