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?

We're trying to build an app that can track the location of the device on-demand. So admins could send a ping signal and get back the current location of the device. Sort of like (find my phone). The functionality should work even if the app is in the background, when the device is locked, and even be available after a device restart without having to open the app first.
We're building the app using React Native and we were looking at some options for background services and push notifications but none seem to satisfy our needs. Any ideas?

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.
I wrote react native application. The application is simple, more informational, it is used by Redux, Saga, several linked npm packages. The app runs in normal mode, not full-screen. The structure of the application was built on the basis of Ignite.
The problem is that on the phone (Samsung Note8) the application is recognized as a game. E.g. while app is running there is a message "The game is running" on the lock screen. Also there are additional buttons for the gamepad or something like that. In additional, app has a paddings on the top and on the bottom when it's working on real device (Samsung Note8). This effect real exists when some games running. When app is running on another device (e.g. ZTE Blade 610) it's running as usual and without any side effects.
The main version is the cause of all is Game Tools that's existed on Samsung Note8 but others apps have no similar effects and running as expected.
Is there a possibility to make a react native app as a real app but not a game? Why Game Tools recognizes my app as a game? Or what is the reason and how can it be affected?
Thanks.
I think there are few possibilities.
you (or one of your dependencies) have included the google play service API which inside of play service API has a module named games that samsung will automatically treat it as game.
You could find which of your dependency is loading google play service API and create a exclude like:
compile (project ('your.dependency')){
exclude group: 'com.google.android.gms', module:'play-services-game'
}
Your application id (can see on build.gradle) is registered on samsung game database. You could check by going into playstore and search for your application id
this is something that can happen on samsung phones due to the package name of your app.
we cant change this after the initial release, you must contact samsung developer support and they can fix it on the fly.
i wrote a gist on github about it:

I'm new to iBeacon's and am trying to understand one simple thing.
Can I use iBeacon to display a notification on a user's iphone without a custom app being installed?
For example, I'd like to build an app that sends out iBeacon messages to people that have an iPhone. When they get near an iPad running my app, it notifies them that they're near my "event", which of course is taking place at the location of my iPad.
Is this possible without the user having already installed another app that I've made to receive notifications of my event?
Note that I'm open to any other tech or ideas that would make this work. I know that Apple does this with their Apple Stores, but I'm guessing they can do this because they already have an app installed on the users device - probably the "AppStore" app.
You typically need an app for any iOS notifications on seeing an iBeacon. That is what Apple does for their stores.
The only exception is if you use Passbook to set up a notification trigger. But you still need the user to install your Passbook entry.
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.
