I am working on an app right now, which should track your GPS location to track your movements. Which mean your phone should track your position even when the app is not active.
How can I achieve this in react native? I've been struggling already a long time now.
If you develop on Android you can use Headless JS with this tutorial.
If you are on IOS you can use this library.

I want to display a video player and contols it in react native but that video player is in kotlin language, So how can control and display android native activity and controls it in react native ?
Yes you can make a Video Player from native side, and expose via NativeModules and pass some props.
Ive done it a long time back and its possible, you can pass URL, height width etc . but im not sure about how well can you fetch the controls etc.

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.

I have been searching through the Expo documentation and haven't been able to find anything.
Is it possible to bring an app to the foreground using expo?
e.g. if I made a simple alarm clock - would it be possible to bring the app to the foreground and show an alarm screen without actively clicking on a notification?
I'm interested in both iOS and Android - any information is very much appreciated.
I want to learn and know how to use the camera roll API on Android.
I stayed up all night and didn't sleep. I can use expo to get the camera, and I have seen the cameraroll working fine on iOS. Some people I have seen on Stack Overflow using the cameraroll API from react-native on Android without any third party, but never seen a full code example it's going to be between 30 to 50 lines. I've checked the documentation, and it mentioned Android, but the steps where used for iOS.
Everyone seems to be running away from it, and some people are unclear about it.
I want to build an app that mute the device in certain time of the day with React Native, that says, it should start running in the background once the phone is started. Is that possible? Or its something had to be done in the actual native code? I did research online but can't find a solution at all.
