I am trying to develop in android-studio on MAC and I am coming across a weird problem. Within the activity code I can not refer to an image which lies in the mipmap folder. In particular I am have created a notification as:
...
Notification notify = new NotificationCompat.Builder(this)
.setContentTitle(title)
.setContentText(body)
.setSmallIcon(R.drawable.ic_launcher)
.setContentIntent(startPendingIntent)
.build();
...
and I receive the error "cannot resolve symbol ic_launcher". Strange is also the problem, that I can not copy-paste the icons into the drawable folder which is empty. Where and how should I place the icons in order to visible within the code in android studio?
