edit parse user information when logged in as other user in android

I am using parse.com in my android application.when i visit other user's profile , i am able to follow that user but when i follow him value in following column of current logged in user's object is updated, but at the same time the user's value whom i followed is not updated It Gives:

06-27 05:11:44.521: E/AndroidRuntime(2459): java.lang.IllegalArgumentException: Cannot save a ParseUser that is not authenticated.

Here is my android code package com.example.wavie.parseQueryRunner;

import android.content.Context;

import com.parse.GetCallback;
import com.parse.ParseException;
import com.parse.ParseObject;
import com.parse.ParseQuery;
import com.parse.ParseUser;

public class FollowUserClass {
    private String id;
    private Context context;

    public FollowUserClass(String id, Context context) {
        this.id = id;
        this.context = context;

    }

    public void follow() {
        ParseUser currentUser=ParseUser.getCurrentUser();
        currentUser.addUnique("following", id);
        try {
            currentUser.save();
            ParseQuery<ParseObject> query=new ParseQuery<ParseObject>("_User");
            query.getInBackground(id, new GetCallback<ParseObject>() {

                @Override
                public void done(ParseObject object, ParseException e) {
                    // TODO Auto-generated method stub
                    if(e==null && object!=null){
                        object.addUnique("followers", ParseUser.getCurrentUser().getObjectId());
                        try {
                            object.save();
                        } catch (ParseException e1) {
                            // TODO Auto-generated catch block
                            e1.printStackTrace();
                        }
                    }

                }
            });
        } catch (ParseException e) {
            // TODO Auto-generated catch block
            e.printStackTrace();
        }



    }
}

in the code section constructor takes the object id of the user whom i want to follow.first it updates current logged in user adds taken id in following field(array).

then i tried to make update in other user's object by adding line

    object.addUnique("followers", 
ParseUser.getCurrentUser().getObjectId());

but when i save it gives parse user should be authenticated before ssaving

i found the answer the next day i asked this question.that time the single way to do this is by deploying cloud code. actually the user i wanted to update was other user so it is not possible to update someone's else information in the database.parse provides a solution to do this in android(possible in js) by deploying a cloud code on the server. parse gives a command line tool to do this for linux run following command to install curl -s https://www.parse.com/downloads/cloud_code/installer.sh | sudo /bin/bash

after successfull installation a folder named parse will be created in home/etc/. now type command parse $configure accountkey -d on terminal ,it will ask for your parse credentials. now type parse command on terminal to select one of your existing application. now you open main.js file in home/etc/parse edit. switch to terminal deploy code by using $parse deploy command. now you are good to go cloud code has been deployed

The error mentions the issue here. The user is not authenticated to perform the operation. This happens when a user updating a a row in parse is not the one who has created the respective row.

So probably you should give write access to the user who is updating the entries.
