Setting alarms daily android

Question

I want to make my application set alarms every day at lets say 7 am a list of pills for the user. So far I have been doing it when a user adds a new pill, I will set the alarm directly, but I want to make it set alarms for today only. I am able to get a list of pills for some day using xpath, and getting the pills in a list. Now I was thinking if this is feasible to have some kind of hidden activity that keeps running or something that will set the daily pills. If someone could give me directions as to what I should be looking for to solve this problem, any kind of help would be appreciated.

Answer 1

You should use: Alarm Manager. And place it in Service. Read also about BroadcastReceiver

Answer 2

I will give an idea for this.

1. Schedule the first Alarm at 7 am using the set method of AlarmManager and register a BroadcastReceiver to be executed at 7 am using the same AlarmManager.

2. At 7 am your Alarm and BroadcastReceiver will execute. In the onReceive method of your BroadcastReceiver again set the Alarm and BroadcastReceiver so that it becomes a self loop.

pseudo code to set broadcastReceiver class:

Intent intent = new Intent(this, broadcastReceiver.class);
                intent.putExtra("subject", subject);
PendingIntent pendingIntent = PendingIntent.getBroadcast(this,
                        0, intent, PendingIntent.FLAG_ONE_SHOT);
AlarmManager am= (AlarmManager) getSystemService(Context.ALARM_SERVICE);
am.set(AlarmManager.RTC_WAKEUP, "Your specific time", pendingIntent);

broadcastReceiver.class:

public class TimeAlarm extends BroadcastReceiver {

    @Override
    public void onReceive(Context context, Intent intent) { 
//set the alarm and broadcast receiver again
}
