Research direction

Start at BaseViewAdapter.java:37, where the stack trace shows the DataBindingAdapter failure during RecyclerView binding, and reproduce the NoClassDefFoundError in an Android example using the adapter. Trace how the generated BR class is referenced and verify that binding a RecyclerView item completes without the reported exception.
