Fragment : Unknown animation name objectanimator

Question

I'm trying to do a flipping card animation between two fragment like in --> Displaying Card Flip Animations by using:

private void switchFragment(Fragment fragment) {
        FragmentManager fragmentManager = getSupportFragmentManager();
        FragmentTransaction fragmentTransaction = fragmentManager
                .beginTransaction();

        if ((fragment != null) && !(fragment.equals(currentFragment))) {

            if (transactionByMenu) {
                fragmentTransaction.setCustomAnimations(android.R.anim.fade_in,
                        android.R.anim.fade_out);
            } else {
                fragmentTransaction.setCustomAnimations(
                        R.animator.card_flip_right_in,
                        R.animator.card_flip_right_out);
            }

            Fragment nextFragment = fragment;
            fragmentTransaction.hide(currentFragment);
            fragmentTransaction.show(nextFragment);

            currentFragment = nextFragment;
        }
        fragmentTransaction.commit();
    }

The transaction in if(transactionByMenu){...} works but not in else{...}

I'd check my libs and stuff and i'm currently target higher than api 11 but I still have this error message:

It's been two day I'am stuck with this, thank you in advance.

Answer 1

I believe you are trying to use objectAnimator in support fragments library, but it was added in Android Api level 11.

Answer 2

If you declared your object animation in an xml file, be sure to put it into the animator folder and not the anim folder to tell android to use the new animation framework.

Here from the documentation :

To distinguish animation files that use the new property animation APIs from those that use the legacy view animation framework, starting with Android 3.1, you should save the XML files for property animations in the res/animator/ directory (instead of res/anim/). Using the animator directory name is optional, but necessary if you want to use the layout editor tools in the Eclipse ADT plugin (ADT 11.0.0+), because ADT only searches the res/animator/ directory for property animation resources.
