I've started a Monaca project, imported the official Onesignal plugin and it's working OK.
The problem is that I couldn't find a way to send a custom sound and small icon in Android. I've place a mp3 file under /res/android/raw/ and a small white-only image in /res/android/screen but they aren't used.
I've tried to include and exclude file extensions in the notification to no avail. Also tried to place the files on the root fo the project.
Has anyone been able to do this? Thanks in advance.
