这是用于更新键“amithabh”的值的代码,但是 put 方法出错。这个 add 以及 remove 方法工作正常。服务器连接良好

package com.example.androidparse;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;
import android.util.Log;

import com.parse.GetCallback;
import com.parse.ParseException;
import com.parse.ParseInstallation;
import com.parse.ParseObject;
import com.parse.ParseQuery;
import com.parse.SaveCallback;

public class MainActivity extends AppCompatActivity {

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

        ParseQuery<ParseObject> query = ParseQuery.getQuery("Tweet");
        query.getInBackground("qDGilscXDH", new GetCallback<ParseObject>() {
            @Override
            public void done(ParseObject object, ParseException e) {
                if(e == null){
//                    object.add("Amitabh","KBC");
                    object.put("Amitabh","kbc");
                    object.saveInBackground(new SaveCallback() {
                        @Override
                        public void done(ParseException e) {
                            e.printStackTrace();
                        }
                    });

                    Log.i("string",object.get("Amitabh").toString());
                    Log.i("success","saved succesfull");
                }else{
                    Log.i("not saved",e.getStackTrace().toString());
                }
            }
        });

        ParseInstallation.getCurrentInstallation().saveInBackground();
    }
}

在解析服务器上更新值的代码
输出错误
