That is why it is allways some homeFragment or fl what ever that you set in onCreate. Because whenever you rotate, the onCreate will execute and set your fragment object to the first one So … Read more

You should simply implement the Parcelable class for your object and use Bundle#putParcelableArrayList() in onSaveInstanceState() and onRestoreInstanceState(). This method will store an ArrayList of Parcelables by itself. Because the subject of Parcelables (and Serializables and Bundles) sometimes makes … Read more
