I want to create an reminder app on android. How it works after closing the app? Thank you.
Its called services. You can run process in background once you get permission from user.
please learn more about services from here:

I want to open activity via fcm notification when app is closed and kill from background,ideal state. this time i need to open app. have any solution plz give m suggestion.
thanks in advance
I don't think that is possible with the lates Android versions. Maybe you should check this docu on when an Activity from an App can be started when it's not in the foregrounf.
i am building an android app which retrieves location data from the device when its running as background service and when its connected to the server it would send the gps data to the server. The functionality of the app must not stop when the app is closed. Can you guys guide me through the process, or provide me some reference or sample code to do this. I am really struggling to make the app run in the background when its closed.
-Thanks
There is a sample app on the Xamarin documentation site that appears to match [1]
However, I would ask to clarify if, when you say "when the app is closed" are you referring to it being backgrounded, or the application being completely closed from the application manager? Either way, background services may be helpful as well [2]
Thanks!

Hi I am very new to android development and so require your help. I am using google places api to get a list of places around a user. Based on this list, I want to send push notifications to users. I have written the code for this function and it is working properly. However, how can I make this function run continuously even when the app is closed ? For example, lets say this function is called collect_send_notification(). I want this particular function to run every 15 minutes in the background even if the user had closed the app. I am sure this is possible but need some guidance. Thank you.
You need to learn about android Services.
You can use the AlarmManager to run your code after a certain time. Here is a link to the android reference.
http://developer.android.com/reference/android/app/AlarmManager.html
I think this is what you're looking for:
[http://developer.android.com/reference/android/app/Service.html][1]
and read more about local/global services.
I am makin an android application on Emergency communication.I want my application should run all the time and whenever it needs it should be able to run.I want that user should not be able to close it by any means.Like Google Maps application which is restarted again on killing its all activities and even we force close it,it will be restarted.
Seems you are learning app development ... but this is not the way you should pose question here... you should post what you have done and code issues and not ask for an entire class...
But i will try to answer your question are you trying to create an app which when started wont be able to be closed and come back to home screen ???!!!!!
See you are creating an app which will run on android operating system which is similar to linux so you must follow the Activity
LifeCycle
I remember i created an app where there were shortcuts on screen so using that i was directing the user to specific links but you can use for calling etc.. i donno if that is what you are searching for...
You might create a notification bar if you want which cannot be cancelled and you can place the code in the intent which will be called from this...
Also services are there which u can utilized what other users have suggested...
thx
You could use an extra service running in the foreground, but there will be always a notification of this service in the notification bar.
See here: http://developer.android.com/guide/components/services.html#Foreground
Do you know if it is possible to launch a service directly after the installation of my application on the phone ?
Thanks
No, this is not possible or supported in Android. You can do it the first time the App is opened.
No this is not possible. But you can check if your application is first started.
