The error message "java.lang.IllegalArgumentException: Target must not be null" typically indicates that you are trying to use a null object reference.
It is possible that the error is occurring because you are passing a null value to the Picasso library when trying to load an image.
Please check the following:
- Verify that the image URLs you are passing to the Picasso library are not null.
- Make sure that the ImageView that you are using to display the image is not null.
- Check the lifecycle of your recycler adapter and make sure that the adapter is being used correctly.
- Check if the onBindViewHolder is being called and the values passed to it are not null.
It is possible that the error is not related to your toggle button implementation, but rather an issue with the Picasso library. It is also possible that the error is occurring in some other part of your codebase. I suggest you to take a look at the full crash log to determine the source of the problem.
