Proof of concept Xamarin Android Alarm Manager

my project is really simple I just need it to proof a theory, I need an android application to schedule 3 alarms 2 minutes apart from each other so for example if the alarm is set at 10:5, then the second should be at 10:7 and the third at 10:9. The alarm should trigger a broadcast receiver and the broadcast receiver should show a toast with the time of the alarm. Currently I already have code that do the same as the above but every time any of the alarms trigger the broadcast receiver get call as many times as alarms have so in the case I explained above the broadcast receiver will be called 9 times in total 3 times each of the alarm is trigger. what I expect is that the code trigger the broadcast receiver just 1 time per alarm. if you are going to write a proposal for this please write the word BroadCast so I know you have read all the description
