這不是下單模式，U不能使用它

Question

在我的提醒應用程序，如果我選擇哪一個剛剛去世的時間，然後點擊App不工作，得到以下錯誤：

這裏是我使用AlarmReceiver.java

public void setRepeatAlarm(Context context, Calendar calendar, int ID, long RepeatTime) { 
     mAlarmManager = (AlarmManager) context.getSystemService(Context.ALARM_SERVICE); 

     // Put Reminder ID in Intent Extra 
     Intent intent = new Intent(context, AlarmReceiver.class); 
     intent.putExtra(ReminderEditActivity.EXTRA_REMINDER_ID, Integer.toString(ID)); 
     mPendingIntent = PendingIntent.getBroadcast(context, ID, intent, PendingIntent.FLAG_CANCEL_CURRENT); 

     // Calculate notification timein 
     Calendar c = Calendar.getInstance(); 
     long currentTime = c.getTimeInMillis(); 
     long diffTime = calendar.getTimeInMillis() - currentTime; 

     while(diffTime < 0) { 
      diffTime += RepeatTime; // at this line getting error 
     } 

     // Start alarm using initial notification time and repeat interval time 
     mAlarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME, 
       SystemClock.elapsedRealtime() + diffTime, 
       RepeatTime , mPendingIntent); 

     // Restart alarm if device is rebooted 
     ComponentName receiver = new ComponentName(context, BootReceiver.class); 
     PackageManager pm = context.getPackageManager(); 
     pm.setComponentEnabledSetting(receiver, 
       PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 
       PackageManager.DONT_KILL_APP); 
    } 

我該如何解決這個問題，它的代碼？

Answer 1

我認爲反應信號3是一個ANR的症狀。崩潰之前應用程序是否掛起？如果是這樣，那可能是因爲循環永遠不會結束。

你確定RepeatTime總是> 0（特別是不是= 0）嗎？

喜歡的東西：

while(diffTime < 0) { 
     Log.d("SOME_TAG", "set diffTime to " + diffTime); 
     diffTime += RepeatTime; // at this line getting error 
    } 

不應超過幾行顯示更多。

更新：

您應該確保無論是報警在未來或重複時間大於0

if (diffTime > 0 || RepeatTime > 0) { 

     // set the alarm only if the parameters are consistents 

     while(diffTime < 0) { 
      diffTime += RepeatTime; // at this line getting error 
     } 

     // Start alarm using initial notification time and repeat interval time 
     mAlarmManager.setRepeating(AlarmManager.ELAPSED_REALTIME, 
       SystemClock.elapsedRealtime() + diffTime, 
       RepeatTime , mPendingIntent); 

     // Restart alarm if device is rebooted 
     ComponentName receiver = new ComponentName(context, BootReceiver.class); 
     PackageManager pm = context.getPackageManager(); 
     pm.setComponentEnabledSetting(receiver, 
       PackageManager.COMPONENT_ENABLED_STATE_ENABLED, 
       PackageManager.DONT_KILL_APP); 

    }
