本地通知每個月的Android

Question

我使用下面的代碼

AlarmManager service = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE); 
Intent i = new Intent(this, AlarmReceiver.class); 
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
PendingIntent pending = PendingIntent.getBroadcast(this, 0, i,PendingIntent.FLAG_CANCEL_CURRENT); 
Calendar cal = Calendar.getInstance(); 
// Start 30 seconds after boot completed 
cal.add(Calendar.SECOND, 30); 
// 
// Fetch every 30 seconds 
// InexactRepeating allows Android to optimize the energy consumption 
service.setInexactRepeating(AlarmManager.RTC_WAKEUP ,cal.getTimeInMillis(),AlarmManager.INTERVAL_DAY , pending); 

// service.setRepeating(AlarmManager.RTC_WAKEUP, cal.getTimeInMillis(), 
// REPEAT_TIME, pending); 

在我的代碼我希望它工作一天的時間間隔後，並不會爲AlarmReceiver服務的廣播。

但是我想在一個月後發生這種情況。 E，g如果一個人在1月3日安裝應用程序，則下一次警報將在2月3日發生，依此類推。我怎麼能把一個月的時間間隔。

請使用下面的代碼。它與你當前的代碼沒有太大的區別。開機後

AlarmManager service = (AlarmManager) this.getSystemService(Context.ALARM_SERVICE); 
    Intent i = new Intent(this, AlarmReceiver.class); 
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK); 
    PendingIntent pending = PendingIntent.getBroadcast(this, 0, i,PendingIntent.FLAG_CANCEL_CURRENT); 
    Calendar cal = Calendar.getInstance(); 
    // Start 1 month after boot completed 
    cal.add(Calendar.MONTH, 1); 
    // 
    // Fetch every 1 month 
    // InexactRepeating allows Android to optimize the energy consumption 
    service.setInexactRepeating(AlarmManager.RTC_WAKEUP ,cal.getTimeInMillis(),AlarmManager.INTERVAL_DAY , pending);
