FirebaseRecyclerAdapter Give NoSuchMethodException

I know from https://github.com/firebase/FirebaseUI-Android/issues/46, to fix NoSuchMethodException :

make sure that your TaskViewHolder class is public
if your TaskViewHolder is an inner class of e.g. your activity, make sure it's static

The solution is worked only if I build the app using debug keystore. But after I build the app using release keystore, I still get NoSuchMethodException. minifyEnabled=false

Tested on Android One Marshmallow Mito A10, Honor 6 and marsmallow emulator

Stack trace error:

My ViewHolder in seperate CommentHolder.java file with public :

public class CommentHolder extends RecyclerView.ViewHolder
    implements View.OnClickListener {
TextView tvComment = null;
TextView tvUser = null;
TextView tvDate = null;
String emailComment = "";
String commentKey, catalogKey;

FirebaseAuth auth;
FirebaseDatabase database;
CommentHolder(View row) {
    super(row);
    auth=FirebaseAuth.getInstance();
    database=FirebaseDatabase.getInstance();

    tvComment = (TextView) row.findViewById(R.id.comment);
    tvUser = (TextView) row.findViewById(R.id.user);
    tvDate = (TextView) row.findViewById(R.id.datecomment);

    row.setOnClickListener(this);
}

@Override
public void onClick(final View v) {

    if (auth.getCurrentUser() == null || auth.getCurrentUser().getEmail() == null) {

        Toast.makeText(v.getContext(), "Harap login terlebih dahulu", Toast.LENGTH_LONG).show();
        return;
    }
    if (!auth.getCurrentUser().getEmail().equalsIgnoreCase(emailComment)) {
        Toast.makeText(v.getContext(), "Anda hanya dapat mengedit komentar yang Anda buat", Toast.LENGTH_LONG).show();
        return;
    }


    final View form = ((Activity) v.getContext()).getLayoutInflater().inflate(R.layout.dialog_comment, null);
    EditText etComment = (EditText) form.findViewById(R.id.editTextComment);
    etComment.setText(tvComment.getText().toString());

    AlertDialog.Builder builder = new AlertDialog.Builder(v.getContext());

    builder
            .setTitle("Komentar Anda")
            .setView(form)
            .setPositiveButton("Kirim", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    final EditText etComment = (EditText) form.findViewById(R.id.editTextComment);
                    DatabaseReference commentRef = database.getReference(MyConstants.FB_COMMENT)
                            .child(catalogKey).child(commentKey);
                    Comment comment = new Comment(auth.getCurrentUser().getUid()
                            , auth.getCurrentUser().getEmail(), etComment.getText().toString());
                    commentRef.setValue(comment);

                }
            })
            .setNegativeButton("Batal", null)
            .setNeutralButton("Hapus", new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialogInterface, int i) {
                    DatabaseReference commentRef = database.getReference(MyConstants.FB_COMMENT)
                            .child(catalogKey).child(commentKey);
                    commentRef.removeValue();
                }
            })
            .show();


}

void bindModel(String catalogKey, String commentKey, String comment, String emailComment, String dateComment) {
    tvComment.setText(comment);
    String temp = emailComment.replaceAll("(?<=.).(?=[^@]*?.@)", "*");
    tvUser.setText(temp);
    tvDate.setText(dateComment);
    this.emailComment = emailComment;
    this.commentKey = commentKey;
    this.catalogKey = catalogKey;
}

}

FirebaseRecyclerAdapter code:

mAdapter = new FirebaseRecyclerAdapter<Comment, CommentHolder>(Comment.class, R.layout.play_row
            , CommentHolder.class, commentRef) {
        @Override
        public void populateViewHolder(CommentHolder commentHolder, Comment comment, int position) {

            Date date = new Date((long) comment.getLastUpdate().get("date"));
            SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd", Locale.getDefault());
            String strDate = simpleDateFormat.format(date);
            commentHolder.bindModel(catalogKey, getRef(position).getKey(), comment.getComment(), comment.getEmail(), strDate);

        }

    };

My Comment.java :

public class Comment {
String uid;
String email;
String comment;
HashMap<String, Object> lastUpdate;

public Comment() {
}

public Comment(String uid, String email, String comment) {
    this.uid=uid;
    this.email = email;
    this.comment = comment;
    HashMap<String, Object> lastUpdateObj = new HashMap<>();
    lastUpdateObj.put("date", ServerValue.TIMESTAMP);
    this.lastUpdate = lastUpdateObj;


}

public String getUid() {
    return uid;
}

public String getEmail() {
    return email;
}

public String getComment() {
    return comment;
}

public HashMap<String, Object> getLastUpdate() {
    return lastUpdate;
}
}

As @CommonsWare guess. The problem is solved after adding public to CommentHolder constructor.

public CommentHolder(View row) {
super(row);
auth=FirebaseAuth.getInstance();
database=FirebaseDatabase.getInstance();

tvComment = (TextView) row.findViewById(R.id.comment);
tvUser = (TextView) row.findViewById(R.id.user);
tvDate = (TextView) row.findViewById(R.id.datecomment);

row.setOnClickListener(this);
}
