Пишу пробное приложение чат, ни как не могу решить данную ошибку:

(com.google.firebase.database.DatabaseException: Can't convert object of type java.lang.String to type android.example.mychat.AwesomeMessage)

Bесь интернет облазил, все руководства прочитал, помогите пожалуйста.

MainActivity:

public class MainActivity extends AppCompatActivity {

myAdapter:

public class AwesomeMessageAdapter extends ArrayAdapter<AwesomeMessage> {
    public AwesomeMessageAdapter(Context context, int resource,
                                 List<AwesomeMessage> messages) {

    }

    @Override

        if (convertView == null) {
            convertView = ((Activity) getContext()).getLayoutInflater()
                    .inflate(R.layout.message_item, parent, false);
        }

        ImageView photoImageView = convertView
                .findViewById(R.id.photoImageView);
        TextView textTextView = convertView

        TextView nameTextView = convertView
                .findViewById(R.id.nameTextView);

        AwesomeMessage message = getItem(position);

        boolean isText = message.getImageUrl() == null;

        if (isText) {
            textTextView.setVisibility(View.VISIBLE);
            photoImageView.setVisibility(View.GONE);
            textTextView.setText(message.getText());
        } else {
            textTextView.setVisibility(View.GONE);
            photoImageView.setVisibility(View.VISIBLE);
            Glide.with(photoImageView.getContext())
                    .load(message.getImageUrl())
                    .into(photoImageView);
        }

        nameTextView.setText(message.getName());

        return convertView;
    }
}

Class:

public class AwesomeMessage {

    String text;
    String name;
    String imageUrl;

    public AwesomeMessage() {
    }

    public AwesomeMessage(String text, String name, String imageUrl) {
        this.text = text;
        this.name = name;
        this.imageUrl = imageUrl;
    }

    public String getText() {
        return text;

    public void setText(String text) {

    }

    public String getName() {

    }

    public void setName(String name) {
        this.name = name;
    }

    public String getImageUrl() {
        return imageUrl;
    }

    public void setImageUrl(String imageUrl) {
        this.imageUrl = imageUrl;
    }
}

Ошибка в MainActivity :: ChildEventListener :: onChildAdded на строке dataSnapshot.getValue(AwesomeMessage.class);

(на всякий случай мой message_item.xml):

<?xml version="1.0" encoding="utf-8"?>

    android:layout_width="match_parent"
