BinaryListAdapter<T> class abstract

An abstract adapter for encoding and decoding lists of binary data.

This adapter handles the conversion between a list of type T and a Base64-encoded String for storage in SharedPreferences. It uses a specified byte size to read and write binary data.

Subclasses must implement the read and write methods to define how individual elements of type T are read from and written to binary data.
