I wanted to create a few number of alarms which has different times and canceled them one by one when I select each. I could create few alarms. But I have no idea how to cancel them when I select.
Currently, alarm canceling process is working for the last alarm which I put.
This is my work,

Have any about my problem ?
Too much of a code,your code seems to work fine
To cancel all alarams use must cancel them one by one and would need all request codes
private void cancelAlarm(int RSQ) {
textAlarmPrompt.setText(
"\n\n***\n"
+ "Alarm Cancelled! \n"
+ "***\n");
Intent intent = new Intent(getBaseContext(), AlarmReceiver.class);
PendingIntent pendingIntent = PendingIntent.getBroadcast(getBaseContext(), RSQ, intent, 0);
AlarmManager alarmManager = (AlarmManager) getSystemService(Context.ALARM_SERVICE);
alarmManager.cancel(pendingIntent);
}
And then use to cancel each one individually
cancelAlarm(1);
cancelAlarm(2);
cancelAlarm(3);
cancelAlarm(4);
To cancel all
for(int i=1;i<5;i++)
{
cancelAlarm(i);
}
