Headless not working Android when app Inactive

Your Environment

• Plugin version: 2.4.4
• Platform: Android
• OS version: 8
• Device manufacturer / model: One Plus 5
• React Native version (react-native -v): 57
• Plugin config

{
            minimumFetchInterval: 15, // <-- minutes (15 is minimum allowed)
            stopOnTerminate: false,   // <-- Android-only,
            startOnBoot: true,         // <-- Android-only
            enableHeadless: true    // <-- Android-only
        }

Expected Behavior

When the app goes into inactive mode, none of the headless tasks run. We force bg-tasks by running adb shell cmd jobscheduler run -f <app-id> 999 An app on android becomes inactive after some time. It can also be forced by running: adb shell am set-inactive <app-id> true

Actual Behavior

The background tasks don’t run. When running adb shell am set-inactive <app-id> false the last task fires.

Steps to Reproduce

See above.

Context

I want to keep running bg-tasks even when android throws the app into inactivity.

From the same android documentation of Doze mode:

As soon as the user wakes the device by moving it, turning on the screen, or connecting a charger, the system exits Doze and all apps return to normal activity.

This doesn’t seem to work for Background-Fetch. Once the phone enters doze mode once, the app background fetch never resumes to its intended schedule, even if the phone is plugged in or the screen is turned on. The app needs to be explicitly opened for the background-fetch schedule to resume.

Can we reopen this ticket?

You can think of the orange bars in the image as background-fetch events. The longer the device sits idle and unplugged from power, the less frequent that fetch events will fire. You might only get 1 per hour after long periods sitting idle.
