Description

AppState.addEventListener('change', this._handleAppStateChange)

I called this in a js file on global scope. It works fine initially but if the app stays in the background for too long, it will stop working even after the app resumes (not restarts, app was still in the background).

Tested on Samsung Android 8.0.

It looks like you are using an older version of React Native. Please update to the latest release, v0.57 and verify if the issue still exists.

The "⏪Old Version" label will be removed automatically once you edit your original post with the results of running react-native info on a project using the latest release.

Hey @James2516, sorry for the delay here

This API is not supported globally, it needs to be inside a react component to make sure the app lifecycle is managed correctly, see the docs here: https://facebook.github.io/react-native/docs/appstate

Hi @rickhanlonii, thanks for the clarification.
It is not stated on the docs that the API call should be inside a React component. You might want to add that to the docs?
