I was receiving about 7 notifications badly the user logged in that they were placed by an alarm and sent to an alarm receiver where he creates the notification each with his id.
I ran the app again with the same code (exactly the same) and this error appears every time I try to create bulk notifications on login. In other parts of the code it works normally.
Could not find class 'android.app.Notification$Builder'
Does anyone know how to solve it?
