Gist to send data to a fragment from an activity using the newInstance method

AddActivity .java

public class AddActivity extends AppCompatActivity {
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
      openFragmentA(/*Pass your eight strings*/);
    }
}
public void openFragmentA(/*eight Strings*/){
    FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
    FragmentA myFragment = FragmentA.newInstance(/*eight Strings*/);
    ft.replace(R.id.your_placeholder, myFragment);
    ft.commit();
}

FragmentA.java

public class FragmentA extends Fragment {
  
  public static FragmentA newInstance(String a, String b, ...) 
  {
    FragmentA myFragment = new FragmentA();
    Bundle args = new Bundle();
    //Do the same for all the strings you want to pass
    args.putInt("StringA", a);
    args.putInt("StringB", b);
    
    myFragment.setArguments(args);
    return myFragment;
  }
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {
        // Inflate the layout for this fragment
        return inflater.inflate(R.layout.fragment_a, container, false);
      
      //Get the arguements you passed from the newinstance method
      getArguments().getInt("StringA", "DefaultValue");
    }
}
