Could someone explain about when this exception occurs?

public class IllegalArgumentException extends RuntimeException

Thrown to indicate that a method has been passed an illegal or inappropriate argument.

Somewhere in your code, you are passing an illegal argument to the method startSettlingAnimation() (BottomSheetBehavior class). This method is throwing the exception:

void startSettlingAnimation(View child, int state) {
    int top;
    if (state == STATE_COLLAPSED) {
      top = mCollapsedOffset;
    } else if (state == STATE_HALF_EXPANDED) {
      top = mHalfExpandedOffset;
    } else if (state == STATE_EXPANDED) {
      top = getExpandedOffset();
    } else if (mHideable && state == STATE_HIDDEN) {
      top = mParentHeight;
    } else {
      throw new IllegalArgumentException("Illegal state argument: " + state);
    }
    if (mViewDragHelper.smoothSlideViewTo(child, child.getLeft(), top)) {
      setStateInternal(STATE_SETTLING);
      ViewCompat.postOnAnimation(child, new SettleRunnable(child, state));
    } else {
      setStateInternal(state);
    }
  }

Your error is: Illegal state argument: 5. 5 is the int value of STATE_HIDDEN. So while your state is STATE_HIDDEN (5), your mHideable boolean is false. So, the basic suggestion would be to set the mHideable = true;

Without any code, that's as much as I can tell you.

I think the problem is that the `bottomSheetBehavior.setHideable(true);` part is not being called at some conditions inside your `bind()` method, since it also might not be called for some reason. Try debugging your app with break points. — Sergey Emeliyanov, Dec 18 '17 at 15:57
The test team are running monkey test, it make hard to debug. But i believe that problem is here : `public void onStateChanged(@NonNull View bottomSheet, int newState)` — Anderson K, Dec 18 '17 at 16:47
I think the accepted answer should be @SerjArdovic 's comment the `bottomSheetBehavior.setHideable(true);` needs to be called. — Michael Osofsky, Mar 13 '19 at 18:52

For me problem was resolved by sheetBehavior.setHideable(true); It seems when setHideable is false and then setting state to BottomSheetBehavior.STATE_HIDDEN exception will occurred

As @Serj Ardovic explain it s the Hideable

I wanted to add that you can also put it in the xml :

<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
android:id="@+id/bottom_sheet"
android:layout_width="match_parent"
android:layout_height="wrap_content"
app:behavior_hideable="true"   <- this here
app:layout_behavior="com.google.android.material.bottomsheet.BottomSheetBehavior">
