android.graphics.drawable.BitmapDrawable cannot be cast to android.graphics.drawable.AnimationDrawable

This error occurs when you try to cast a BitmapDrawable object to an AnimationDrawable object. The BitmapDrawable class is used to represent a bitmap image as a drawable object, while the AnimationDrawable class is used to create animations by combining multiple drawable objects.

To fix this error, you need to make sure that you are using the correct type of drawable object in your code. If you are trying to use an AnimationDrawable object, make sure that you are initializing it properly and adding the correct frames to it. If you are trying to use a BitmapDrawable object, make sure that you are not trying to cast it to an AnimationDrawable object.

If you are still having trouble resolving this error, try reviewing your code and checking for any other potential issues that may be causing the error. You may also want to consult the Android documentation or seek help from the Android developer community for further assistance.
