🐞Workmanager can't execute Post requests on Android 15 #649
Description
- I have read the README
- I have done the setup for Android
- I have done the setup for iOS
- I have ran the sample app and it does not work there
Version
| Technology | Version |
|---|---|
| Workmanager version | 0.9.0+3 |
Describe the error
When the app is running and the callbackDispatcher executes, it does everything Ok, but when the app is closed it triggers as normal but on Android 15 it shows this error when doing a Post request (if the app is still open there is no problem):
The connection errored: Failed host lookup: 'myweb.com' This indicates an error which most likely cannot be solved by the library.
I got two devices, a Samsung Tab A9 which I updated yesterday to Android 15 and now I found this issue where before there wasn't any and it would execute the code correctly, and a Samsung Tab S9 wich is still on Android 14 and the code runs just fine.
