Android set multiple alarms using Alarm Manager

Problem: I am scheduling multiple alarms using Alarm Manager, but only one gets triggered.

#Android

Other day, I was scheduling two alarms simultaneously, at some point in future, but only one was being triggerd.

When to use Alarm manger :

The Alarm Manager should be used for cases where you want to run your application code at a specific time in future, even if your application is not currently running.

In my case, I had to trigger push notification in 3 and 6 hours,after user has performed an action in the app.

When creating a pendingIntent that will perform a broadcast, we need to provide a unique request code parameter for the sender.

The problem was I was passing 0 as requestCode when creating pending intents for both alarms.

PendingIntent.getBroadcast(appContext, 0, intent, 0)

Intent(appContext, AlarmReceiver::class.java).let { intent ->
            intent.putExtra(ARG_RECIPE_ID_KEY, recipeId)
            intent.putExtra(ARG_ALARM_TYPE, alarmType.name)
            PendingIntent.getBroadcast(appContext, unique_id, intent, 0)
        }

Solution:

I created a wrapper to be injected in a class from where I needed to set an alarm.

Implementation :

Next up, perform long running IO tasks in BroadcastReceiver.onReceive
