Circular reveal animation

AnimationUtils.java

public class AnimationUtils {

          int height = revealSettings.getHeight();
          int duration = context.getResources().getInteger(android.R.integer.config_mediumAnimTime);

          //Simply use the diagonal of the view
          float finalRadius = (float) Math.sqrt(width * width + height * height);
          Animator anim = ViewAnimationUtils.createCircularReveal(v, cx, cy, 0, finalRadius).setDuration(duration);
          anim.setInterpolator(new FastOutSlowInInterpolator());
          anim.start();
          startColorAnimation(view, startColor, endColor, duration);

still getting same error.

Whoever is getting error please create your own class like this inner or separate whatever you prefer:
first listen to what Rumaan said, add this to your gradle:
annotationProcessor 'com.google.auto.value:auto-value:1.4'
provided 'com.jakewharton.auto.value:auto-value-annotations:1.4'
annotationProcessor 'com.ryanharter.auto.value:auto-value-parcel:0.2.5'

and then create an abstract class:

private abstract static class AutoValue_RevealAnimationSetting extends RevealAnimationSetting {
AutoValue_RevealAnimationSetting(int centerX, int centerY, int width, int height) {
super();
}
}
and then just implement the methods when returning like this:
public static RevealAnimationSetting with(int centerX, int centerY, int width, int height) {
return new AutoValue_RevealAnimationSetting(centerX, centerY, width, height) {
@OverRide
public int describeContents() {
return 0;
}

        @Override
        public void writeToParcel(Parcel dest, int flags) {

        }

        @Override
        public int getCenterX() {
            return 0;
        }

        @Override
        public int getCenterY() {
            return 0;
        }

        @Override
        public int getWidth() {
            return 0;
        }

        @Override
        public int getHeight() {
            return 0;
        }
    };
}

Now the error should go away. Happy coding :))

I solved this issue by following the above solutions,

Added in my build.gradle

annotationProcessor 'com.google.auto.value:auto-value:1.5.2'

compileOnly 'com.jakewharton.auto.value:auto-value-annotations:1.4'

annotationProcessor 'com.ryanharter.auto.value:auto-value-parcel:0.2.5'

My class RevealAnimationSetting looks like,

`@AutoValue
public abstract class RevealAnimationSetting implements Parcelable {
public abstract int getCenterX();
public abstract int getCenterY();
public abstract int getWidth();
public abstract int getHeight();

public static RevealAnimationSetting with(int centerX, int centerY, int width, int height) {
    return new AutoValue_RevealAnimationSetting(centerX, centerY, width, height) {
        @Override
        public int describeContents() {
            return 0;
        }

        @Override
        public void writeToParcel(Parcel dest, int flags) {

        }

        @Override
        public int getCenterX() {
            return centerX;
        }

        @Override
        public int getCenterY() {
            return centerY;
        }

        @Override
        public int getWidth() {
            return width;
        }

        @Override
        public int getHeight() {
            return height;
        }
    };
}

private abstract static class AutoValue_RevealAnimationSetting extends RevealAnimationSetting {
    AutoValue_RevealAnimationSetting(int centerX, int centerY, int width, int height) {
        super();
    }
}
