react-native-foreground-event-service

This library enables you to run a foreground service and schedule a job in given interval. In the library AlarmManager is used to schedule the jobs. So you may want to have a look at the Android AlarmManager documentation at this url; https://developer.android.com/reference/android/app/AlarmManager

Note: As you might know IOS does not have such property as Foreground service, so this library for only Android development.
