Saving a fragment state after screen rotation

Question

I am trying to cope with saving state fragmentin order to avoid problems when rotating the screen. This happens strangely: when I rotate the screen for the first time, everything works, but when I rotate the screen for the second time, the application crashes:

Here is the piece of code for the fragment

    //save information: a string and an image
    @Override
    public void onSaveInstanceState(Bundle bundle) {
        super.onSaveInstanceState(bundle);
        bundle.putString("namesurname", nameSurnameString);
        bundle.putParcelable("imgprofile", bitmap);

    }

    @Override
    public void onActivityCreated(Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        if (savedInstanceState != null) {
            //Restore the fragment state
            this.nameSurname.setText(getArguments().getString("namesurname"));
            this.profileImage.setImageBitmap((Bitmap)getArguments().getParcelable("imgprofile"));
        }
    }

There is part of the action code here

//save the fragment
@Override
protected void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    //THE NEXT ONE IS LINE THAT RAISES THE EXCEPTION  WHEN I ROTATE THE SCREEN 
    //FOR THE SECOND TIME
    getSupportFragmentManager().putFragment(outState, "profileFragment", profileFragment);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    FacebookSdk.sdkInitialize(getApplicationContext());
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_drawner);

    //getting stuff from intent....

    if (savedInstanceState != null) {
        //Restore the fragment instance

        this.profileFragment = (ProfileFragment) getSupportFragmentManager().getFragment(
                savedInstanceState, "profileFragment");
        restoredProfile=true;

    }

mistake is

Answer 1

Look at the error, it says that your fragment is not in your manager, because when you change the state of the screen, your activity will be rebuilt, and the fragment will also be destroyed. Now the fragment is not created, not the instance, so your fragment is not in supportFragmentManager.

, setRetainInstance(true) .
