Fragment - InstantiationException: no empty Constructor -> Google Maps v2?

Question

I get this error message, when I open a closed App again via App-Change button:

Caused by: java.lang.InstantiationEx         


        

Answer 1

  private Entity mEntity;
  public YourFragment() {}
  public static YourFragment getInstance(Entity mEntity) {
    YourFragment fragment = new YourFragment();
    fragment.mEntity = mEntity;
    return fragment;
  }

when you use this fragment,just call the static method getInstance.
