Q:

Can't update rows of google spreadsheet API using Android Studio.

I am writing a code for an app using the android studio and so far I am able to retrieve data from a google spreadsheet. 
I used the following code: 
package com.example.tolotrasamuel.aluoneapp;

}

This works perfectly but when I am trying to edit the rows of the spreadsheet, it gives me an error: 
I used the following code:

I don't know where am I doing wrong. I think this is problem of authentification.
I would be glad if you can help.

A:

I see you are using the google spreadsheet API V3. This version is deprecated. Instead, use the new version: V4. Follow this documentation to know how to update rows
