I'm creating an Android app where in the user can set the daily reminder, and at the designated time, the phone's alarm goes off and an activity is launched.
App uses the latest version of the SDK and the emulator. How do I get started with this?
Thanks,
Sri
You're looking for AlarmManager.

I am new to coding. I am using Android Studio with Java. I spent the last 3 hours looking for how to set up a notification display at the top when the user leaves the app so they can always click on the notification when they want to return to the app but I couldn't find anything with that action I need.
The app tracks the users GPS and I want them to be able to always be aware that when the app is running it will continue to track their GPS. So my idea is to have a notification window pop up whenever they leave the app so they can be aware the app is running in the background.
Any help will be much appreciated! I am building this app on my own as a passion project and I am taking the Udacity Google Android course. I finished the course early and working on this app for fun. We didn't learn about Notifications or GPS tracking but I am doing my best to learn new things. Thank you for your patience and help!

Use a foreground Service. For any background logic, you should be using a Service anyway, and in Android Oreo and above, you're required to have it be a foreground Service, meaning it posts a Notification.
You can then add a PendingIntent to that notification set to reopen your app. See Android's Notification documentation on how to set a PendingIntent. You'll want to use PendingIntent.getActivity(), where the Intent you pass is new Intent(someContext, YourActivity.class).
Not too experienced with mobile development, but I wanted to know if this was possible.
After the user installs the app (android or ios), the app should at least once a day "wake-up" and show a push notification to the user.
Is this possible?
If I understood you correctly, I believe that you need setup a recurring alarm using AlarmManager. You also need to setup starting alarm service on device reboot. You can write a method that does what you want so it get executed when the alarm runs e.g. show notification. The following links should help you:
Repeat Alarm Example In Android Using AlarmManager
How does an Android alarm app or any other time based notifications app like Calendar, Clock, etc work? More specifically, how does it show up the notifications at exactly the time specified by the user? Does it constantly run in the background and as soon as the required time comes up, does it show the notification? Or does it schedule the notification in Android's kernel before exiting? I am working on an app that needs to give the user notifications at times specifies by him. I am not able to figure out how to do that.
Maybe what you mean is to create an alarm, you can see this example.
In android device if any user set alarm in default app then how can I detect or receive that alarm when its execute in my application. I don't know its possible or not if anybody knows please suggest me how can I do that.
Im creating an alarm-based app right now, this is what i found earlier :
Android get list of active alarms
Get all alarms saved in the alarm application
Its a bad news.
I want to develop an alarm clock like services in android that is the app should run on the some user entered time and even if the mobile is switched of that app should work as alarm clock works .
Use an AlarmManager. See this SO question. You'll also probably want to recreate your alarms on reboot (they're normally cleared then); see this android developers thread.
