unresolved reference MergeAdapter

Question

I was using MergeAdapter in my code . Every thing worked fine until I updated my RecyclerView version to 1.2.0-alpha04 . Now my code shows unresolved reference MergeAdapter

implementation "androidx.recyclerview:recyclerview:1.2.0-alpha04"

Answer 1

MergeAdapter has been renamed to ConcatAdapter in 1.2.0-alpha04 release, so refactor your code and change MergeAdapter to ConcatAdapter

You can see the discussion over here https://issuetracker.google.com/issues/158019211

MergeAdapter has been renamed to ConcatAdapter to avoid any confusion with different data merging behaviors
