Clock Alarm & background running

Hi everyone,

I am making a clock alarm app for android platform. My question is how to open my app even when the phone is lock down (with screen off) at a specific time pre-programmed by the user.

As you know for example when a call comes in, the screen turns on and the "phone" application is displayed. This is the same effect I want to create. So maybe I have two questions:

1.- Should I run my app at background?, so even when it is closed, it will bring me up the alarm. So how to do it?
2.- When the time arrives, how should I turn on screen to display my app.

Thanks in advanced.

 

Don't use unity for such a simple thing..

an alarm clock doesn't need a physics engine and AI build in to it.

it's gonna drain the battery super fast compared to other "regular" apps

learn how to make a custom app, it's not hard at all, an alarm clock is pretty trivial

 

Exactly as SparrowsNest said:
Use e.g. AndroidStudio together with Java (the differences between Java and C# and really small) and research "scheduled jobs in android" as that's probably the best way to achieve what you want to.

 

Yeah well actually my app is a little bigger than that. Open my application in a programmed way is just a future.

 

If you want to use C# i think you can use xamarin form(or something like that) works with c# and a bit of xaml i think

 

Create a background service and send notification to the user when the time comes. But do not open your application directly, and probably you can't regardless. (I'm not sure, I'm not a mobile developer per say)
To create background service you will need native tools.

 

And perhaps no one wants additional background processes. Specially on mobile.
