I am developing an app that uses location infos. I can get user location while the app is working on foreground and background. But this does not work when app is killed. Is there any way to process geofire when app is killed?
Thanks.

How can I use background-fetch in Expo for sending phone location to server for every minute. I want task to perform when app is not running in background for both iOS and Android. Is this possible with normal Expo or do I have to eject, what path should I follow? Or at least how can I keep app open in status bar constantly like sports apps with small area or Spotify's music player part?
Fire base push notification is not working when app Killed or force stop in Mi, Vivo, OPPO.In my code, android firebase push notification is working fine in Moto g4 and Samsung, but it's not working in Mi, Vivo, OPPO when app is killed. But it's working when autoStart on. That means the background service killed if the app is autostart off. How can I solve this issue?
I already tried like following link oppo, vivo app kill notification not coming in android fcm. But it opens the settings and user needs to switch on option. However, I need automatically on that.
I am working in an application that detects any Beacons nearby and gives and alert in the form of local notifications for iOS. I used TiBeacons library for titanium which did the work but I am right now stuck with an issue where I need to keep the Application running even when the user swipes off the application from background.
I was able to make it work in background which is the paused state,but is it possible to make it restart itself in the background when the user swipes the app from the background processes running,maybe with a delay if not promptly?? Thanks
There is no way to restart application after user removed it from a memory. This would be huge security bridge allowing developers to do lots of evil things to customers' devices.
You can run your code only when app is in foreground and background but never when it's killed.
You can try activate your app by receiving notification from Apple Notification Center Service:
The purpose of the Apple Notification Center Service (ANCS) is to give Bluetooth accessories (that connect to iOS devices through a Bluetooth low-energy link) a simple and convenient way to access many kinds of notifications that are generated on iOS devices.
The ability to detect iBeacons after the app was killed in the task switcher was only added in iOS 7.1. Also, I believe this functionality requires that beacon monitoring be set up with the app's main AppDelegate object as the CoreLocation delegate. I do not know much about Titanium, but glancing at the source, it appears it does not do this, and instead uses a different class as the CoreLocation delegate. This may explain why this does not work for you.
If my suspicion is true, you would not be able to detect after the app is killed using an unmodified version of that library.
Since I am not a Titanium expert, it would be best if someone who knows more about it could confirm or refute my suspicion.
I am running my application on iOS 7.0.1 & iPod Touch 5th generation device. When I follow below steps my app quits with below error on Xcode 5 without any error in console
App quit Unexpectedly Terminated due to Memory Pressure
Steps:
1) Run my application using Xcode 5. Login & then go to Home
2) Click on Home button so that my app enters in background (I can see my app is in background)
3) Start inbuilt Photos app from iOS. Click 1 or 2 pictures
4) After taking 1-2 pictures , App quit Unexpectedly Terminated due to Memory Pressure
I am not doing anything in my app. When I checked the CPU usage its 0% & Memeory used = 15.2 MB
Also there is no other app running in the background except my app.
Can anybody help with this ? Thanks
I am not getting why this is happening. If I don't use Photos.app then app works smoothly.
There's nothing you can, or should, do about this. You application is no longer in the foreground, and the foreground app (photos) is asking for more memory. To supply this, iOS will terminate any apps running in the background. It doesn't matter how much memory your app is using, iOS will terminate background apps as long as the foreground app requires more memory.
Once your app enters the background you can expect it to be terminated at any time. To improve the user experience, you can look at Enabling State Preservation and Restoration in Your App. This in theory allows your app to start where it left off when the user comes back to it.
I'm building an app that uses the camera. As many know, the camera uses a lot of memory and often throws a memory warning.
The app works well and as expected. However, when streaming Spotify in the background, my app crashes.
Is there any way to stop/pause a background app?
in iOS, every app runs in its own sandbox environment that cannot interact with other apps which are running so there is no way your app can pass on any kind of instruction (pause/stop) to other app running in background.
