如何在android中解码json emoji

import org.json.JSONException;
import org.json.JSONObject;
import org.apache.commons.lang3.StringEscapeUtils;

public class MainActivity extends AppCompatActivity {
    private TextView textView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        textView = findViewById(R.id.textView);

        // 示例JSON字符串
        String jsonString = "{\"message\": \"Hello \\ud83d\\ude0a\"}";

        try {
            // 解析JSON对象
            JSONObject jsonObject = new JSONObject(jsonString);

            // 获取包含emoji的字段
            String message = jsonObject.getString("message");

            // 解码emoji
            String decodedMessage = StringEscapeUtils.unescapeJava(message);

            // 在TextView中显示解码后的字符串
            textView.setText(decodedMessage);
        } catch (JSONException e) {
            e.printStackTrace();
        }
    }
}
