I'm building an android app using the managed workflow.
The logs come from Pixel emulator running android 9, but I've reproduced the problem on a real Pixel device running android 10.

Steps to Reproduce

In an expo app, create a BackgroundFetch task, and register it with startOnBoot: true
build an android app with the managed workflow, install the app on the phone

Run the app, make sure that the background task works as expected
( in the example below adb logcat | grep ReactNative should show running background task )
For example in the https://github.com/jeromecornet/expo-android-backgroundfetch/raw/master/first_run.log, you will see:
11-15 14:02:57.200 4386 4473 I ReactNativeJS: running background task

Restart the phone

the app registers the task again, and starts the timer
for example in https://github.com/jeromecornet/expo-android-backgroundfetch/raw/master/after_reboot.log you will see

11-15 14:07:39.732  3987  3987 I TaskService: Registered task with name 'background-fetch-restart-test' for app with ID '@jerome.cornet/expo-android-backgroundfetch'.
11-15 14:07:39.732  3987  3987 I TaskService: Handling intent with action 'android.intent.action.BOOT_COMPLETED'.
11-15 14:07:39.736  3987  3987 I BackgroundFetchTaskConsumer: Starting an alarm for task 'background-fetch-restart-test'.

Wait 1 minute or so for the task to be executed

Expected Behavior

The task should run, showing the expected console.log line

Actual Behavior

Instead, the standalone app crashes and the background task gets unregistered, the following message appears in the logs instead

TaskService: Cannot execute background task because application loader can't be found.

From there the task gets unregistered and no longer works until the app is manually started again.

here's a relevant snippet of adb logcat (full log at https://github.com/jeromecornet/expo-android-backgroundfetch/raw/master/after_reboot.log)

Reproducible Demo

I have put a minimal sample app here https://github.com/jeromecornet/expo-android-backgroundfetch. I set the minimumInterval to 1mn for debugging, but I've had the problem with a 15mn interval so I don't believe it's related.

The matching apk (built with expo build:android) is here: https://github.com/jeromecornet/expo-android-backgroundfetch/raw/master/app.apk
the full adb logcat output of the app working when executed is at https://github.com/jeromecornet/expo-android-backgroundfetch/raw/master/first_run.log
the full adb logcat output of of the app crashing upon reboot is at https://github.com/jeromecornet/expo-android-backgroundfetch/raw/master/after_reboot.log

Looks like it's very similar to #6017 . I'm going to close this issue and link back to the original

So what's our option right now? Stop using Location.startLocationUpdatesAsync until it's updated?

I guess so - I just find it weird that this has not been fixed yet. Seems like a big problem, especially for those working on transportation apps.

Yup. That's our exact vertical. We need to track the user's location even when they're not using the app. Funnily enough, I've never personally encountered this issue but there are enough crashes in the Google Console to warrant a fix.

same issue here, google play console actually flagged our app with Bad Behaviour as this bug is causing a 15% crash rate to our production app.
