Who can help me on this wired exception? Feel I AM CRASHING. When I just add masters beans or remove it, or drag on it. After that, commit and notifyDataSetChange(), crash happened. It's very wired. Because when I debug on it. I found the if case is false. The program should not enter the throw cause. It 's very terrible for my debugging. I give up and hope to find some help here. Thanks a lot!
Here below is my code: Using
implementation ('com.h6ah4i.android.widget.advrecyclerview:advrecyclerview:0.11.0@aar'){
transitive=true
}
