The best library is : CircularReveal

use :

Use regular RevealFrameLayout & RevealLinearLayout

<io.codetail.widget.RevealFrameLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <!-- Put more views here if you want, it's stock frame layout  -->

    <android.support.v7.widget.CardView
...
        />

</io.codetail.widget.RevealFrameLayout>

and :

  View myView = findView(R.id.awesome_card);

    // get the center for the clipping circle
    int cx = (myView.getLeft() + myView.getRight()) / 2;
    int cy = (myView.getTop() + myView.getBottom()) / 2;

    // get the final radius for the clipping circle
    int finalRadius = Math.max(myView.getWidth(), myView.getHeight());

    SupportAnimator animator =
            ViewAnimationUtils.createCircularReveal(myView, cx, cy, 0, finalRadius);
    animator.setInterpolator(new AccelerateDecelerateInterpolator());
    animator.setDuration(1500);
    animator.start();

This library is simple and works very nice in pre lollipop.
