How to build keepAwake into your React Native app

Mobile devices typically enter sleep mode or lock the screen after a short period of inactivity to conserve power, which can be inconvenient for apps requiring continuous screen display, such as video players or GPS navigation. To mitigate this, developers can implement a wake lock, or "keep awake" function, which prevents the device from sleeping while the application is in use. This article guides users on using the expo-keep-awake package in React Native applications to maintain screen activity during video playback. It includes instructions for setting up a basic video player, caching video content using the expo-file-system module, and employing the useKeepAwake and activateKeepAwakeAsync functions to control the wake lock status based on playback conditions. The tutorial emphasizes the importance of using the keep awake feature judiciously to avoid unnecessary battery drain or adverse user experiences.
