Describe the error Ever since i installed the example app and tried the work manager plugin, you get this log every few minutes on your device after uninstalling the app. I am not sure why its trying to find the app but one guess would be a task that was scheduled using such app is trying to get called but cant find the app to execute it. 

android.content.pm.PackageManager$NameNotFoundException: dev.fluttercommunity.workmanager.example

Does the job not get cancelled or deleted automatically if the app gets uninstalled?

Update: installed the example app again and cancelled all tasks using the app. After uninstalling the app again, the namenotfoundexception seems to be gone.

So could something be done that if the app gets uninstalled, all the tasks that were scheduled using such app gets cancelled automatically?

Update2: there seem to be a different kind of log now

Quite interesting, but this seems to be an Android quirk. Uninstalling a App must remove all of it's traces, including scheduled background jobs.

The next version will be based on Workmanager 1.8.1 - we can try again then, but this surely looks like a platform issue.
