Before start build app bundle in release mode I built apk on debug. Then I installed this apk on my phone for testing all functions but background service didnt work and notification phone was in preparing. I wait two hours and nothing change, service didnt start until I reset phone. Then I tested on many phones versions to make sure issue isnt in phone.

We have to open the application at least once after the installation process is complete. It is necessary because we have to update the callback handle with the latest binary. Note that, if you run the app in debug mode using USB, the binary will not shipped to your phone until you full-restart the app (re-run your app from the IDE).

[MohamadKattan]

Already i did all this Befor send to you .

[ekasetiawans]

@MohamadKattan OK, I'll give it a try when I have the chance.

[MohamadKattan]

Hi. I am having the same issue. I just added your plugin to my Flutter 2.0 app and followed the example, excluding the Flutter 3.0 line. Trying to run on Android through the USB debugger and Android Studio.

For me, the issue seems to be with the AndroidConfiguration not registering the callback for onStart. I am seeing errors in the log stating that after runService is called it is throwing an error that the callback handle is not found. This is leaving the background service in the "Preparing" state.
