Hi
I tried to create an application for my LMS and I use this tutorial:
https://docs.moodle.org/dev/Setting_up_your_development_environment_for_Moodle_Mobile_2
So here is my problem, when I try to prepare the android app with `npx ionic cordova platform add android` it's got error and I used --verbose for see the error detail and realized the error reason is :
ERROR: Missing source for "adaptive-icon" (sources: resources/android/icon-background.png, resources/android/icon-background.jpg, resources/android/icon-background.jpeg)
and I check moodle git repository , but there isn't any icon-background file, How can I solve it?
here is verbose detail:
```
