java.lang.ClassCastException: android.support.transition.Fade cannot be cast to android.transition.Transition?

That exception was thrown when trying to add animations to replacing fragments. According to this answer, stackoverflow, the transition framework cannot be applied to fragments but this post shows you can How to use Material Transitions in Fragment Transactions Code I tried is below

final JobFragment jobFragment = JobFragment.newInstance(job);
    final Fragment previousFragment = fragmentManager.findFragmentById(R.id.content);
    final FragmentTransaction fragmentTransaction = fragmentManager.beginTransaction();
    //exit transition
    Fade exitFade = new Fade();
    exitFade.setDuration(1000);
    previousFragment.setExitTransition(exitFade);
    //enter transition
    Explode enterExplode = new Explode();
    enterExplode.setDuration(1000);
    jobFragment.setEnterTransition(enterExplode);

    fragmentTransaction.replace(R.id.content, jobFragment).addToBackStack("jobDetails")
            .commit();

The answer is in your title - you have the wrong import, one is for support library, the other isn't.. Check you have consistent imports.

Example:

import android.support.transition.Fade;
import android.support.transition.Transition;

or:

import android.transition.Fade;
import android.transition.Transition;

For compatibility use the support (added in 24.2.0) version.
