I just implemented oneSignal in my project to send push notifications.
Notifications are sent correctly when the application is launched but when I put in background I got this error :
Im working with Eclipse and I know that is really recommended to migrate to Android Studio since Eclipse is not supported any more. The problem is that my client’s project is too old and I couldn’t perform the migration properly.
I think that the problem is caused by Android Support V4 but I don’t know how to fix. After googling and trying many solutions I still got the same issue.
I am an Android Developer beginner, any help is much appreciated, thanks.
