I want to make an api call to backend when the app is in background (closed) mode in react native.
Basically, the function should check for internet connection and then get some data from async storage , then make an api call to sync the data with the db.
I'm not familiar with native code.
Can anyone help me with how this can be achieved ? Any suggestions is appreciated.
There is no way to make API calls in the background for iOS devices as Apple Policy restrict developer to run tasks in background iOS.
So, If you are looking to make API calls in the background for Android devices.
Then you can use the below dependency to run API calls in the background.

I am building a React Native app and would like to add weekly local notifications. The notifications should include dynamic data, such as a screen time increase, which will be calculated right before the notification is sent.
When the user enables the notifications by clicking "Enable Weekly Reports", the scheduleNotificationAsync method is called, taking the title parameter as input. However, the title will change over time.
What is the best way to periodically schedule notifications with dynamic content in React Native using the expo-notifications API?
Note: The BackgroundFetch method only works when the app is in the background, not if the app has been terminated or after a device reboot.

I'm trying to figure out how the apps like facebook messenger shows a circle of user image on screen when a new message comes, and Uber driver app shows the uber icon on screen when the user minimizes it. Is there anyway that I can show a customized component on phone screen even when the app is not open?
This Stackoverflow thread explains how to replicate in react native by changing the java code as its not supported by react native yet.
this feature is not support directly from react native and also this is not supported in ios therefore only you could implement it with java native code in android. to do that you should write a service in android which handle this element life cycle.

There was a task to make push notifications when the application is completely off.
Need to implement some Background Task Manager that will be at intervals such as a minute to check for new notifications for a specific user. In simple words, make a background fetch.
Previously, I implemented push notifications in the application.But they work only when the application is enabled or simply minimized. When the app is completely off Push does not work.
Has anyone done this before ?
I use Expo for this project.
Part of our React Native App lets users use it in the background while they use other apps.
If the user then force quits the app while our app is in the background we want to do some cleanup and send some analytics. Since we can't get the applicationWillTerminate event in React Native we need to do this cleanup in the native side.
So we were wondering if there is a way to access the Redux store in this event. Or what is the suggested way to handle this?
Do compiled Expo.io React Native applications support "Always On" background location tracking, even when the app is not in use?
Expo just implemented Background Location
Instead of using the watchPositionAsync method, you will have to utilize TaskManager.defineTask method to register the background task out outside of the React event loop. Then, start the task with Location.startLocationUpdatesAsync.
Short answer is no. Quoting the "Why not expo" page:
Expo apps don’t support background code execution (running code when
the app is not foregrounded or the device is sleeping). This means you
cannot use background geolocation, play audio in the background,
handle push notifications in the background, and more. This is a work
in progress.
You will need to detach your app and add this behavior yourself, still doing so you lose some of the expo capabilities.
