Recently i have got java.lang.IllegalArgumentException: Invalid Transition types.
This exception happens on android api 19 and it appeared after i have updated android build tools and support libraries to version 27.

Does anyone know what has changed with KitKat transitions?

    Fragment fragment = new  Fragment();

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) {

        Transition transition = new AutoTransition();

        fragment.setSharedElementEnterTransition(transition);

    }



    String backStateName = fragment.getClass().getName();

    FragmentManager manager = getFragmentManager();

    FragmentTransaction ft = manager.beginTransaction();

    ft.addSharedElement(view, "TransitionView");

    ft.replace(R.id.mainActivity_container, fragment, backStateName);

    ft.addToBackStack(backStateName);

    ft.commit();

Full exception:

UPDATE

After changing from if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.KITKAT) to if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP) I don't get exception.

check your fragment import like below..

import android.support.v4.app.Fragment;

if you used addSharedElement make change in app level gradle file api level 21.

     minSdkVersion 21

Looking at the change here it looks like it should probably read 'must' use support transitions rather than 'can' use them. Try changing your AutoTransition from android.transition.AutoTransition to android.support.transition.AutoTransition and it should work perfectly without needing any SDK version checks.

You are mixing transitions from the support library and the platform.
For example.:

import android.support.transition.AutoTransition;

import android.transition.Fade;

Change that to only use support library, like this:

import android.support.transition.AutoTransition;

import android.support.transition.Fade;

After switching to androidX, I got this error because some import was from

android.package

and some from

androidx.package
